✦ Synopsis

Composite films from polyaniline (PANi) and polyurethane (PLJ), with high flexibility and mechanical strength similar to pure PU and conductivity dose to pure PANi, have been obtained by electropolymerizing aniline on a PU/Pt electrode in water/acetonitrile/ethylene glycol electrolyte solution. In the composite films, PANi is dispersed, in the form of particulate, inside and on the inner surface of the PU substrates. It is found that the electropolymerization reaction of aniline proceeds much faster in basic solution and composite film as prepared shows higher conductivity than that in acidic solution. PANi in PU/PANi composite f i l m is protonic-acid-doped and is conducting even in case it is electropolymerized in a basic electrolyte solution.
