抄録

The processes of deposition of precursor LB films and imidization to polyimide LB films were monitored by weight change using a piezoelectric quartz plate as a microbalance. N-Octadecylpyrrolidine was better than N, N-dimethyloctadecylamine as a long alkyl amine to obtain the Y-type multilayer. Although imidizaion using the solution of acetic anhydride and pyridine was performed within several hyndred seconds in benzene, it did not complete in hexane, whereas initial imidization speed was faster in hexane. Swelling would be important factor for imidization process, because benzene make the LB film swell more than other solvents.
