Polystyrene, A Green Solution

By | Uncategorized | 10,784 Comments

Polystyrene foam has been utilized in a number of fields for over 40 years because of its superior characteristics.
Although its usefulness is widely recognized, there had been a period in which a movement against polystyrene foam was launched due to incorrect information. According to the wrong information, toxic gas was produced from incineration of polystyrene foam, compounded by alleged damages to incinerators and alleged use of harmful chlorofluorocarbon gas in its production, among others. Contrary to these claims, only water and carbon gas, and not toxic gas, are produced from incineration of polystyrene foam. There are no negative effects on incinerators, either, and no harmful CFC gas is used in the production of polystyrene foam.

Polystyrene foam is the lightest in weight and energy-saving when used as various packing materials, and the emission of CO2 in the final incineration is small, thus contributing to the control of global warming.

In addition, we are making industry-wide efforts to recycle polystyrene foam, which we believe will help protect the environment of the earth.

We sincerely hope that in using polystyrene foam, customers correctly understand it.

1)polystyrene foam products

Of polystyrene foam, Expanded Polystyrene or EPS is thermoformed in steam by placing polystyrene beads containing foaming agent in a mold. This is usually called molded product. It is light, and has excellent shock absorbing and thermal insulation performance, and for that reason used as impact absorbing material and containers.Another is polystyrene paper or PSP, which is made by softening polystyrene resin blended with foaming agent, and extruded in a sheet form. This sheet is again softened and formed by thermoforming into trays and others for use as fish, meat and other food containers.

2)Helping people with the following features

  1. Polystyrene foam has superior thermal insulation performance. For that reason, it is an essential material in cold storage and heat retention of food and others.
  2. It is light weight, excels in shock absorption performance, and therefore is suitable as a damage-prevention material.
  3. It is sanitary, water-resistant, and thus useful in protecting items that are susceptible to deterioration by moisture.
  4. It is a light and sturdy packing material. Because it is foamed, materials can be saved.
  5. Complex and highly precise processing is possible. Various forming, depending on purposes, can be easily and promptly made.
  6. It can be also used as thermal insulation material for buildings as a useful energy saving material for comfortable lifestyle.

3)For correct understanding of polystyrene foam packing materials

  1. The percentage of polystyrene foam in waste is not large.
  2. The percentage of polystyrene foam in waste is 0.7%.
  3. CFC is not used in the production of polystyrene foam.
  4. Chlorofluorocarbon, which induces global warming with the greenhouse effect it causes and the destruction of the ozone layer, is not used in the manufacturing process.
  5. Toxic gas, such as dioxin, is not produced when polystyrene foam is incinerated.
  6. Polystyrene foam is a substance that does not contain chlorine, and for that reason does not produce dioxin when incinerated alone. In addition, black smoke is produced when air supply is insufficient in incineration, but this is non-toxic soot (carbon).
  7. It helps protection of forests.
  8. By substituting paper trays and impact-absorbing materials with polystyrene foam, the use of pulp can be reduced. This in turn protects forests which absorb and fixate carbon gas, a major cause of global warming.
  9. It is an easily-recyclable material.
  10. Polystyrene foam is easy to visually detect, and therefore a material that can be easily separated and collected. It can be recycled into a raw material for plastics.
  11. It is polystyrene foam that produces little CO2 gas.
  12. When polystyrene foam is incinerated due to significant stains which makes it unsuitable for recycling, it produces only a small amount of CO2 gas which in turn negatively influences global warming. In comparison with cardboard, the amount of CO2 gas produced in incineration is smaller for polystyrene foam.

Breakthrough in 2D polymer for energy storage

By | Science | 7,420 Comments

Polymers, such as plastic and synthetic textiles, are very useful technological commodities that have revolutionised daily life and industries. A research team from the National University of Singapore (NUS) has successfully pushed the frontier of polymer technology further by creating novel two-dimensional (2D) graphene-like polymer sheets.

“In the last century, scientists have successfully developed molecules which can be crosslinked to form one-dimensional and three-dimensional polymers. These are used to produce a wide range of technological products. However, making 2D polymers has met with little success, as most molecules are not flat and they tend to rotate in solution, making it difficult to control their linking to a 2D plane,” said Professor Loh Kian Ping, Head of 2D Materials Research in the Centre for Advanced 2D Materials at NUS. He also holds an appointment with the Department of Chemistry at the NUS Faculty of Science.

Mr Liu Wei, who is the first author of the paper, added, “Our team developed a strategy to make 2D polymer sheets by prepacking flat molecules in a crystalline state and carrying out solid state polymerisation. This approach restricts the rotation of the molecules and allow the 2D polymerisation to take place to form carbon-carbon bonds.” Mr Liu is a PhD student at the NUS Department of Chemistry as well as NUS Graduate School for Integrative Sciences and Engineering.

The novel polymer sheets synthesised by the NUS team are unique because of their good electrical conductivities and highly regular, sub-nanometer sized pores, which can be used to store sodium ions efficiently and safely in sodium ion batteries. Sodium ion batteries are a type of rechargeable metal-ion battery that uses sodium ions as charge carriers. As there is an abundance of sodium, sodium ion batteries are cheaper to produce than lithium ion batteries. However, the disadvantage is that they do not last long. The 2D polymer developed by Prof Loh and his team can be mass produced at low cost for use as the electrode for sodium ion batteries, enabling such batteries to perform at high capacity for thousands of charge cycles.

The design and validation of the novel 2D polymer was published in the journal Nature Chemistry in January 2017. It has also been highlighted in Nature’s News & Views on 23 February 2017.

A two-dimensional challenge

When graphene was first extracted from graphite more than a decade ago, it was touted to be a “wonder material”, and researchers quickly jumped on the bandwagon. This prompted the emergence of 2D materials as a new field of research, and stimulated interest in the organic synthesis of 2D polymers. However, constructing stable 2D conjugated polymers with strong linkages presents complex challenges in synthetic chemistry.

Prof Loh explained, “It is particularly hard to make 2D polymers based on carbon-carbon linkages due to the irreversibility of the reaction. Once an error in bond formation is made, it is locked in and cannot be repaired.” Intrigued by this property, Prof Loh and his team embarked on making 2D polymers with carbon-carbon linkages as they are the most stable type of bonds and can be used in harsh environments – for instance, the polymer can remain stable in water, and is able to withstand acids and heat.

Effectiveness by design

The basic building block used by Prof Loh and his PhD student Mr Liu is a planar molecule that contains several aromatic rings which consist a series of connected carbon double bonds, through which electrons can move about. The ability of the electrons to move increases the electrical conductivity of the polymer, which is important when the material is used in batteries. The researchers designed this aromatic monomer such that an ordered arrangement is formed. Flat molecules are chosen to maximise the chances of cross-linking in 2D.

During their experiments, the NUS researchers discovered that by applying heat to the set of carefully designed, flat monomers which are pre-packed in a specific way, a 2D crystalline polymer is formed. The 2D polymer consists well-defined pores and channels, through which sodium ions can diffuse in and out for energy storage. An individual sheet of this material can be readily peeled using adhesive tape, yielding ultra-thin sheets which are of less than a nanometre.

Most organic materials showed poor performance when used as an electrode in sodium ion batteries due to their poor electrical conductivity and inhomogeneous pores. However, this novel organic 2D polymer material exhibited superior stability. When it was used as the anode material in sodium ion batteries, it can be charged and discharged quickly at room temperature, and retained 70 per cent of its capacity after 7,700 charge cycles, which is unprecedented. The new material also worked well when it was tested as an electrode in lithium ion battery.

Prof Loh said, “Unlike contemporary methods, our approach involved only thermal annealing, without the use of solvents, initiators or catalysts. This straightforward method enables us to fabricate this 2D polymer on a large scale, and at a low cost that is comparable to the cost of mass producing plastic. The use of an organic-based material also provides a safer storage medium for sodium ions due to the more inert nature of carbon materials.”

Future plans

The NUS team’s successful creation of a novel, porous 2D material with enhanced ion storage properties opens up new horizons in the field, and may form the basis of a new branch of crystal engineering. To further their work, Prof Loh and his team are using advanced computational techniques to design other classes of molecular building blocks which can undergo polymerisation in the solid state for the development of other novel 2D polymers.
