Microstructure and thermal behavior of Poly(o-anisidine)/Poly(ethylene terephthalate) composite

Abstract

Poly(o-anisidine)-Poly(ethylene terephthalate) composite film was prepared by chemical oxidative polymerization method. The composite film shows a conductivity of about 15.6 K Δ-1 cm-1 with 3.5 wt. % of POA. Fourier Transform infra-red (FT-IR) and UV-vis spectral analyses reveal the existence of hydrogen bonding interactions between the groups in PET and POA. X-Ray diffraction analysis informs that the amorphous characteristic of PET is affected by the presence of POA in the composite. UV-vis spectral results demonstrate that there exists cross-linking in the composite film when the POA in the composite undergoes doping and dedoping. AFM micrographs confirm the formation of genuine composite between POA and PET.
