摘要：
Polyaniline films doped with varying HCl concentrations (0.2 M, 0.6 M and 1.0 M) were synthesized on glass substrates via oxidative polymerization of aniline. The films were treated with supercritical carbon dioxide (SC-CO2) at 30 MPa and 40 degrees C for 30 minutes. Their structural, optical and morphological properties were studied and compared to conventionally prepared polyaniline films using FTIR analysis, UVVis spectroscopy and scanning electron microscopy. It was observed that supercritical carbon dioxide (SC-CO2) could interact with PANI films that consequently altered the bandgaps and changed the film thickness. SCCO2-treatment also increased the oxidation level of polyaniline films and modified the morphology of polyaniline film doped with 1M HCl.
