Abstract:

In order to expand the application of polypyrrole/silver (PPy/Ag) conductive polyester fabrics, PPy/Ag conductive polyester fabrics were prepared by one-pot method with silver nitrate as oxidant under the condition of plasma pretreatment. The conductive fabrics were characterized by Fourier transform infrared spectroscopy, X-ray diffraction and scanning electron microscopy. The square resistance of conductive fabrics was measured by resistometer and the bacteriostatic effect was tested by agar plate method. The results show that the PPy/Ag conductive polyester fabrics prepared in this study have good conductivity, and have obvious inhibitory effect on Escherichia coli and Staphylococcus aureus. The conductivity of such fabrics is positively correlated with the number of times of plasma pretreatment to polyester fabrics, and the square resistance of conductive fabrics reaches the minimum value of 0.22 kΩ/□ when the number of plasma pretreatment is 4.

Key words: conductive fabric, polypyrrole, silver nanoparticles, plasma pretreatment, polyester, conductivity, antimicrobial property
