The property of PANI /PET composite conductive fabric is studied and characterized,including scanning electron microscope( SEM), infrared spectroscopy, conductivity, wash fastness and mechanical properties. The results show that the optimal polymerization conditions: the molar ratio of ammonium persulfate and aniline is1∶ 1,the concentration of sulfuric acid is 1 mol /L and reaction time is 90 min. Under optimum conditions,the surface resistivity of PANI /PET composite conductive fabric is about 170 Ω. After washed 5 times, the surface resistivity of PANI /PET composite conductive fabric is stable at 1 450 Ω. The breaking strength and breaking elongation of PANI /PET composite conductive fabric decrease compared with PET fabric.展开更多
