Study on O2 Plasma Surface Modification of Aramid Fiber III

The influence of low temperature plasma treatment on the interfacial performance of aramid fiber was studied. SEM and XPS were used to investigate the surface morphology and the chemical elements of the fiber before and after plasma treatment. The etching degree of the surface of aramid fiber was determined by wettability experiments and tensile/bending measurements before and after low temperature plasma treatment. The result showed that under the condition of 200W/10min/10Pa, the etching effect of the surface of aramid fiber was optimal. The wettability of fiber obviously improved and the bending intensity increased by about 30%.but the tensile performance of aramid fiber did not change much.
