Process for the preparation of flexible and free standing conducting polyaniline film

摘要

This invention relates to the preparation of free standing film of conducting polyaniline of varied thickness. The conducting polyaniline film is obtained by use of a functionalised aromatic sulphonic acid as primary dopant and a halosubstituted phenol as secondary dopant. The emeraldine base, primary dopant and secondary dopant are mixed in an appropriate amount and stirred. The resulted homogeneous thick viscous solution cast yields conducting polyaniline film of conductivity more than 10 S/cm.
