Abstract

This paper describes the imidization of PAAS(polyamic acid alkylamine salts) Langmuir-Blodgett (LB) films and the electrical properties of PAAS and polyimide(PI) LB films, The imidization conditons were investigated by TGA(Thermal Gravi-tational Analysis). FT-IR and UV/ visible absorption spectra. A thermal imidiczation was peformed at 300$^{\circ}C$ for 1 hour. The electrical properties of the PAAS and polymide LB films were measured by current-voltate(L-V) characteristics It shows that the electrical condcutivity of PL LB films is about 10 $\^$-15/S/cm which is two orders of magnetiude lower than that of the PAAS LB films A Schottky effect was also observed in both films.
