Özet

One of the most important textile materials, poly(ethylene terephthalate) (PET) fiber, was coated with a semi-conductive polyfuran (PFu) by in situ oxidative polymerization using FeCl3 oxidant in solvent mixture of acetonitrile-chloroform. The effects of polymerization conditions such as volume ratios of acetonitrile/chloroform, monomer concentration, and oxidant/monomer mol ratio were investigated on PFu content (%) of the composites. It was observed that pretreatment of PET in dichloromethane increased PFu content and its coating continuity before polymerization. The highest PFu content (12.0%) was obtained using FeCl3/furan mol ratios of 3.5 in acetonitrile/chloroform mixture (5/1). The density values of the composites with different PFu contents were measured. Composite fibers were also subjected to doping processes with HCl and I-2 vapors, separately, and it was observed that the surface resistivity of PFu/PET (10(12) omega/cm(2)) reached to 53 omega/cm(2) after doping with I-2. The structural, thermal, and morphological characterization was performed with FTIR, XRD, TGA, and SEM, respectively.
