Electroconductive poly(aniline) and poly(pyrrole) composites prepared by latex polymerization processes
Polimery 1997, No 4, 229
Aniline and pyrrole were each polymerized in aqueous vinylidene chloride/methylacrylate/butyl acrylate copolymer solutions to prepare electroconductive polymer composites. The products obtained were examined by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), differential thermal analysis (DTA), elemental analysis, and FTIR spectroscopy to follow the chemical, electrical and mechanical properties and morphology of the resulting composites as also the conducting polymer percentage in relation to chemical polymerization conditions, i.e., monomer/polymer matrix weight andoxidant/monomer mole ratios. Appropriate polymerization conditions enabled conducting composites containing from <5 wt.% to >50 wt.% of poly(aniline) (PAni), but only up to 15 wt.% of poly(pyrrole) (PPy), to be obtained. The electrical conductivities of the PAni and the PPy composites were max. 1.5 and 1 S/cm, resp.
