Özet

A conductive polyaniline (PAn)-polythiophene (PTh)/poly(ethylene terephthalate) (PET) composite fiber was prepared by polymerization of aniline and thiophene in the presence of PET fibers in an organic medium with FeCl3. The effects of polymerization conditions, such as polymerization medium, mol ratios of aniline/thiophene and FeCl3/aniline-thiophene as well as polymerization temperature and time, were investigated on PAn-PTh content (%) and surface resistivity of the composite. The composite with the lowest surface resistivity (1.30 M/cm(2)) was obtained by polymerization of aniline and thiophene (1/3 mol ratio) in acetonitrile/chloroform (1/5 volume ratio) at 20 degrees C. The surface resistivity of the PAn-PTh/PET composite containing 4.8% PAn-PTh was increased from 1.9 M/cm(2) to 270 M/cm(2) at pH 11. The washing durability of the composites was determined with domestic and commercial laundering processes by monitoring the surface resistivity and morphology. The composite was also characterized with FTIR, TGA, elemental analysis, optic microscope and SEM techniques. (c) 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 41979.
