ELECTRICALLY CONDUCTIVE POLYANILINE POLY(BUTADIENE-CO-STYRENE-CO-2-VINYLPYRIDINE) LATEX COMPOSITES/

A series of conducting line/poly(butadiene-co-styrene-co-2-vinylpyridi ne) (PBSP) latex composites was prepared by polymerization of aniline in the presence of PBSP latex. The mass loading of polyaniline in the composite latex can be controlled by varying the PBSP latex/aniline ch arging ratio and oxidant/aniline molar ratio. The composites were char acterized by elemental analysis, transmission electron microscopy and thermogravimetric analysis. The effects of the concentration of the re actants on the conductivity at room temperature and the mechanical pro perties of the composite films formed from the latices were studied.
