The application of LB techniques to conducting polymers is beening reviewed. The main topics are: the preparations of conjugated polymer LB films [including Polypyrrole、 Polythiophene、Poly (p - phenylenevinylene)、Polyaniline and their derivatives ]; characterizations of these LB films ;the relationship between conductivity and molecular structures and fabrication of the polymer molecules. At last
nonconjugated conducting polymer LB films are concerned.
