Effect of low temperature plasma treatment on surface properties of polyphenylene sulfide fiber

The performance of the polyphenylene sulfide fiber (PPS) was investigated by low temperature glow discharge plasma. The experimental results show that under the treatment of different plasma conditions, the PPS fiber surfaces appear the varying degree physics and chemical etching. It's found that the friction coefficient and hydrophilicity of PPS fiber treated by low temperature plasma improve. X-ray photoelectron spectroscopy (XPS) analysis shows that the surface of PPS fiber produced etching, cross-linking, oxidation. Variations of tensile breaking strength of PPS with different parameters are analyzed.
