Reflectance of the irradiated films decreased in the low wavelength regions of visible light, indicating destructive interference
of visible light due to roughened surface. The UV treatment developed the nano-scale roughness on the UHMWPE films
surface, which increased by two-fold from 82.6 to 156.6nm in terms of peak-valley roughness. The UV irradiation caused the
oxygen content of the UHMWPE film surface to increase. Water contact angle decreased from 83.2o to 72.9o and surface
energy increased from 37.8 to 42.6mJ/m2 with increasing UV energy. The surface energy change was attributed to significant
contribution of polar component rather than nonpolar component indicating surface photooxidation of UHMWPE films. The
increased dyeability to cationic dyes may be due to the photochemically introduced anionic and dipolar dyeing sites on the
film surfaces. |
