摘要

A conductive blend of polyaniline (PANI) with sodium form poly(methyl methacrylate-co-acrylic acid) copolymer (PMMAA) was prepared by in situ dispersion polymerization. The PANI-PMMAA blends were characterized with UV-vis, FTIR, and electron paramagnetic resonance (EPR) spectra. The effects of PANI and temperature on the electronic properties of the PANI-PMMAA blends were studied with EPR technique. The PANI and temperature affect the intermolecular interaction between PANI and PMMAA and then determines the EPR parameters (A/B ratio, g factor, T2, ΔH_(pp), N_s, and lineshape).
