摘　　要：用准分子激光照射高分子纤维 ,在纤维表面形成垂直于纤维轴线的周期性柱型结构 ,有利于纤维光学性质和亲和性质的改变。研究了不同激光能量、脉冲次数下的纤维表面形态 ,并初步讨论了高分子纤维的准分子激光表面纹理化形成的机理。A new technique for the surface modification of polymer fibers is introduced by irradiating with UV excimer laser, and this technique can be used to modify the chemical and physical properties of fibers surface. Under certain conditions the irradiation of polymer fibers induced a characteristic morphology on the polymer fiber surface. The original smooth surface of polymer fibers changes its morphology into a rather regular roll-like structure perpendicular to the fiber axis after this treatment. The dependence of characteristic surface data on laser fluency and pulse number is studied. The mechanism for forming periodic surface structure of polymer fibers by excimer laser is also discussed.
