摘要
以接枝N 乙烯基吡咯烷酮 (NVP)的透明双向拉伸聚丙烯 (BOPP)膜为模型 ,用紫外可见分光光度计研究了表面接枝NVP与碘的络合反应 ,考察了聚乙烯吡咯烷酮 (PVP) 碘的配比、络合温度、络合时间对络合反应的影响。结果表明 ,增大络合配比、升高络合温度及延长反应时间 ,均有利于提高与碘的络合程度。在此基础上 ,利用聚丙烯接枝NVP无纺布与碘络合制成了“消毒布” ,并对其杀菌性能进行了初步评价。
With the transparent biaxial orientation polyproplene graft N vinyl 2 pyrrolidone(BOPP g NVP) as samples, the complexation of the surface grafted NVP functional groups with iodine was investigated, and the effects of proportion, temperature and time on complex reaction were studied. The results show that increasing the complex proportion and rasing complex temperature and extending reaction time are favourable to raise the complex reaction degree. Then, the disinfection of PP g NVP I was evaluated using 'disinfectant cloth' prepared by polypropylene non woven g NVP with iodine complexation. It is found that the 'disinfectant cloth' has disinfectant and inhibition action to the bacillus and candia albicans evidently.
