General description
Application
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.
