Abstract:
In order to improve the conductivity of polyester (PET) fiber, a novel method based on in-situ polymerization of aniline for the continuous preparation of conductive yarn was presented, and conductive polyester/polyaniline (PET/PANI) composite yarns were prepared by this method. The influence of parameters of conductive treatment such as concentration of oxidant, doping acid and aniline and processing speed on the electrical conductivity of composite yarns was discussed, and the morphological structure, chemical structure, thermal-gravimentric performance and mechanical properties were also studied. The results indicate that the substrate yarns are coated and filled with conductive PANI. The concentration of reaction mixtures and processing speed greatly affect the conductivity of conductive PET/PANI composite yarns, and the conductivity can reach above 1.5 S/cm. The thermostability of the treated yarns is decreased due to the existence of PANI. Compared with the substrate yarn, the breaking strength and breaking elongation of the treated yarns are increased slinghtly while the initial modular decreases greatly.
Key words: in-situ polymerization, continuous preparation, polyester/polyaniline, conductive composite yarn
