Abstract

Polyimide is a well-known organic dielectric material, which has not only high chemical and thermal stability but also good electrical insulating and mechanical properties. In this research, we have synthesized a polyamic acid(PAA), which is a precursor of the polyimide. To obtain the optimum conditions of polyamic acid alkylamine salt(PAAS) Langmuir-Blodgett(LB) film deposition, the ${\pi}-A$ isotherms were examined by varying subphase temperature, barrier moving speed and spreading amount of solution. Film formation was verified by measuring transfer ratio, absorption of UV/vis spectra and scanning electron microscope(SEM) images.
