Description
Technical field
The invention belongs to polystyrene preparing technical fields, and in particular to a kind of preparation method of conducting polyaniline particle.
Background technology
With the development of the society, polystyrene industry constantly develops, polystyrene products use more and more,
Range is more and more wider, and since polystyrene products follow used i.e. useless principle mostly, thus using while produce it is big
The waste of amount, forms typical white pollution object, and serious harm is caused to environment.How this endanger, such as is solved
These discarded resource re-usings are become one big hot topic topic of current every country by what.
According to the property of polystyrene it is found that it has very high resistivity, thus it is the non-conductive material that insulate well
Material, this is also a big excellent specific property of polystyrene.But it is also due to this property be it in production and transport and use
Very big unnecessary trouble is brought in the process, because it is non electrically conductive material that polystyrene, which belongs to, to which it is namely easy
The material for generating electrostatic will make polystyrene products be easy to inhale when it produces electrostatic during production, carrying, use
Attached dust does not allow processing easy to manufacture, it is also possible to the accidents such as fire, explosion be caused to occur.Therefore the poly- of conductive energy is studied
Benzene composite material, which just seems, very important realistic meaning and wide application prospect.
