AROMATIC POLYSULFONE RESIN FILM, METHOD FOR PRODUCING THE SAME AND SOLUTION COMPOSITION FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain an aromatic polysulfone resin solution composition good in dispersion of an electroconductive carbon black and an aromatic polysulfone resin film using the composition and to provide a method for producing the film. SOLUTION: [1] This aromatic polysulfone resin solution composition comprises (A) an aromatic polysulfone resin, (B) the electroconductive carbon black, (C) a surfactant and a solvent in a weight ratio (A)/(B) of (A) to (B) of 1<=(A)/(B)<=40 and the maximum particle diameter of (B) is <=3μm. [2] The method for producing the aromatic polysulfone resin film comprises (1) casting the aromatic polysulfone resin solution composition [1] onto a support and forming a cast film containing the solvent and (2) evaporating the solvent from the cast film. [3] The aromatic polysulfone resin film is produced by the method for producing the aromatic polysulfone resin film [2].
