Tuning the electrical properties of polyaniline by copolymerization with o-bromoaniline

摘要: Polyaniline, poly(o-bromoaniline) and poly(aniline-co-o-bromoaniline)s have been prepared by chemical oxidative polymerization methods. A series of poly(aniline-co-o-bromoaniline) derivatives has the copolymerization aniline with different mole ratio o-bromoaniline varying feed ratios monomers introduction units along polymer backbone. The morphology each derivative is observed as a porous network aggregated nanoparticles nanoparticle having smaller nanoflake structures. Room temperature electrical conductivity studies reveal that polyaniline value order 10−3S/cm. However, corresponding poly(aniline-co-o-bromoaniline), 10% content, shows fivefold increase relative to homopolymer. were characterized 1H NMR spectrometry, Scanning electron...
