| 摘 要： | 以纳米二氧化钛为抑菌剂,使用表面改性剂改善纳米二氧化钛与SEBS的相容性,制备出具有特殊用途的SEBS/TiO2纳米复合材料,并考察了TiO2添加量对复合材料力学性能的影响.采用SEM表征纳米二氧化钛在SEBS中的分散性能;采用黄色指数间接评价材料的抑菌性能.研究表明:随TiO2表面改性剂用量的增加,SEBS/TiO2纳米复合材料的拉伸强度、伸长率、抑菌性能呈先增加后减少趋势;随TiO2含量的增加,SEBS/TiO2纳米复合材料的拉伸强度、伸长率、黄色指数均不同程度增加.表面改性剂和纳米TiO2用量均为4%时,SEBS/TiO2纳米复合材料的黄色指数最高能达到27,即材料的抑菌性能最佳,此时也可以达到很好的力学性能.

| Abstract: | With the use of nano-titanium dioxide as bacteriostat and surface modifier improving the compatible capability between nano-TiO2 and SEBS,the SEBS/TiO2 nano-composites with special use were prepared and the influence of TiO2 dosage on composite properties was also researched.The dispersed performance of nano-TiO2 in SEBS was characterized with SEM and its bacteriostasis performance was measured with yellow index.The result showed that the tensile-strength,elongation and bacteriostasis performance of SEBS/Ti... |
