摘要
利用天然小分子薄荷醇(MT)的立体防细菌黏附功能,通过酯化反应将其接枝到丙烯酸酐(AC)上,继而聚合生成新型含MT防细菌黏附侧链的聚丙烯酸酯共聚物[P(MAC-co-AA)].采用浸轧法处理棉织物,赋予棉织物优良的防细菌黏附效果.结果表明,当MT和AC物质的量比为2∶1,反应温度为70℃,反应时间为5h时,P(MAC-co-AA)酯化率高达70.9%,对大肠杆菌和金黄色葡萄球菌的防细菌黏附效果最好.相比MT,P(MAC-co-AA)的最大分解温度由130℃提高到252℃,其热稳定性大幅提升.当P(MAC-co-AA)整理液用量为20 g/L时,P(MAC-co-AA)整理棉织物对大肠杆菌和金黄色葡萄球菌的防细菌黏附率高达99.9%.
Abstract
The natural small molecule menthol(MT)with three-dimensional anti bacterial adhesion function was grafted onto acrylic anhydride(AC)by esterification.A new type of polyacrylate copolymer[P(MAC-co-AA)]containing MT anti-bacterial adhesion side chains was synthesized.Then the cotton fabric was treated by dipping and padding meth-od,which imparted the cotton fabric with excellent anti-bacterial adhesion effect.The results showed that when the molar ratio of MT and AC was 2∶1,the reaction temperature was 70℃,and the reaction time was 5 h,the esterification rate of P(MAC-co-AA)reached up to 70.9%.It had the best anti-bacterial adhesion effect on E.coli and S.aureus.Compared with MT,the maximum decomposition temperature of P(MAC-co-AA)increased from 130℃ to 252℃,and its thermal stability was greatly improved.When the concentration of P(MAC-co-AA)solution was 20 g/L,the anti-bacterial adhesion rate of cotton fabric finished by P(MAC-co-AA)to E.coli and S.aureus arrived at 99.9%.
