Description générale

Polystyrene is a high molecular weight aromatic synthetic polymer madefrom the polymerization of styrene. It is a hydrophobic durable thermoplasticwidely used in food containers, packaging foam, and construction materials dueto its good mechanical properties and low cost.

Application

Polystyrene can be added to nanocatalyst suspension to prepare a polystyrene-photocatalyst thick film. This film can be used as a photoanode in an airlift photocatalytic fuel cell (APFC).

Polystyrene can be used as a precursor to prepare graphene film and 3D graphene sponges by pyrolysis under argon atmosphere. The filmogenic property of polystyrene can be exploited to prepare 3D graphene sponges with uniform pore sizes.

It can also be used to prepare dyed polystyrene (PS) film for routine dosimetry in radiation processing. Dyed PS film has high post-irradiation stability.

The separation efficiencies of three different asymmetrical flow field-flow fractionation (AF4) channel designs were evaluated using polystyrene latex standards. Channel breadth was held constant for one channel (rectangular profile), and was reduced either linearly (trapezoidal profile) or exponentially (exponential profile)
