| 摘 要： | 通过在聚丙烯中加入掺杂1%(质量分数)Cu2+的锐钛矿型纳米TiO2作为光敏剂,采用纺粘法设备制备TiO2光敏剂含量为0.0%~1.2%的聚丙烯纺粘法非织造布。将其置于70℃、340 nm紫外光下进行光降解试验,研究样品的力学性能、结晶度和表面形态的变化。结果表明:在聚丙烯中加入Cu2+掺杂的锐钛矿型纳米TiO2,可以催化聚丙烯纺粘法非织造布的光氧化降解和加快降解速度,且在实验范围内光敏剂的含量越大,其光催化降解作用越强。

| Abstract: | 1% wt.Cu~(2+) doped anatase nanoparticles were added into polypropylene as a photosensitizer.The blend was melt spun and heat bonded to prepare spun-bonded PP nonwovens,which contain 0.0%~1.2% wt.doped nano-TiO_2.Having been irradiated with 340 nm UV light at 70℃ for different(periods),the samples were studied by mechanical property analyses,DSC and SEM.It can be concluded that the Cu~(2+) doped anatase nanoparticles is an effective photosensitizer to the photo degradation of polypropylene spunbonded nonwovens,and the more the content of the photosensitizer,the stronger the photo catalysis effect. |
