Opis

Opis ogólny

Poly(1,4-phenylene sulfide)(PPS) is an aromatic polymer that can be used as a polymer backbone or an engineering plastic. It is also called as poly(phenylene sulfide) which can be sulfonated to form ion-exchange membranes for electrochemical applications. It is industrially produced by polycondensation of p-dichlorobenzene and sodium sulfate in N-methylpyrrolidone as a solvent.

Zastosowanie

PPS can be sulfonated to form a proton exchange membrane with zeolite that can be used as an electrolyte with higher thermal stability which facilitates in the fabrication of solar cells. It can also be used in the formation of organic- inorganic nanocomposite membranes using nanozeolites and carbon nanotubes as nanofillers which can be used as high performance gas separation membranes. PPS may be sulfonated and chloromethylated to form novel PPS fiber with higher dyeing ability in dispersive, anionic and cationic dyes.
