Moleculer structure analysis and fabrication of PMDAlMDA Polyimide thin-films

PMDA/MDA Polyimide 박막의 제조와 분자구조 분석

Polyirnide thin films were fabricated an using vapor deposition polymerization apparatus, and their FT-IR and TGA characteristics were investigated. The peaks of $720cm^{-1}$ and $1380cm^{-1}$ show C=O stretch mode and C-N stretch mode, and that of the cured polyimide at $300^{\circ}C$ were saturated. TGI(Thormogravi metric index) was showed at $459^{\circ}C$ from reaserch of thermal resistivity characteristics by TGA.
