General description
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.
