准分子紫外光源对于血液过滤用非织造布表面改性的研究

Research on the surface modification of PBT nonwovens used for filtration blood by UV excimer light

用准分子紫外灯辐照(发射光波长222 nm)熔喷PBT非织造布,对辐照前后材料表面结构以及表面润湿性的变化进行了分析。结果表明,该方法可以有效地改善材料的润湿性。

PBT meltblown nonwovens was irradiated by UV excimer light at wavelength of 222 nm. The surface morphology and surface of the materials both treated and untreated by UV excimer light wettability were analyzed. The result shows that this method could improve their wettability effectively.
