Study on property of PANI/PET composite conductive fabric

摘要

Polyester (PET) fabric was treated with alkali and low-temperature plasma. After that, polyaniline (PANI)/PET composite conductive fabric was prepared through in situ polymerization using aniline as monomer. The structural properties, conductivity, mechanical properties, and wash fastness of PANI/PET composite conductive fabric were studied and characterized. The results showed that the optimal polymerization conditions: the molar ratio of ammonium persulfate and aniline is 1:1 and the concentration of sulfuric acid is 1 mol/L. Under optimum conditions, the surface resistivity of PANI/PET composite conductive fabric was about 170 Ω. PANI particles enter into the fiber and the crystallinity of PANI/PET composite conductive fabric declines and amorphous region of PANI/PET composite conductive fabric increases. The breaking strength and breaking elongation of PANI/PET composite conductive fabric decrease compared with PET fabric. After being washed five times, the surface resistivity of PANI/PET composite conductive fabric is stable at 1450 Ω.
