Abstract
AbstractThis study demonstrates that different modification pulse voltages affect the wetting property of the surface of polyamide 6 (PA6) with a certain regularity. Broadly, the hydrophilic property of PA6’s surface increases with increasing pulsed voltage. Based on scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS) analysis, this paper discusses the mechanism by which high current pulsed electron beam (HCPEB) etching modification influences the surface wettability of PA6. Within a certain range below 28 kV, this effect is caused by an increase of in surface roughness due to HCPEB bombardment of the surface. Within a certain range above 28 kV, HCPEB changes the surface morphology, resulting in changes to the wetting property. Furthermore, by using various pulsed voltages to modify the PA6 surface, this study investigated the ability of the Wenzel model to explain changes in the water contact angle and wetting property of PA6’s surface.
