설명

일반 설명

Poly(pyromellitic dianhydride-co-4,4′-oxydianiline), amic acid solution (PAA) converts to polyimide at 300^oC. The FTIR spectra indicates a carbonyl stretch of carboxylic acids in PAA at 1650 cm^-1. Following the imidization process, the peak at 1720cm^-1 grows, indicating the formation of imide group.[1][2]

애플리케이션

It is used as a precursor for polyimide coatings.[3]
It may also be used as a precursor for the preparation of carbon hollow fiber membranes.[4]
