摘要:
利用体内细菌感染部位微环境偏酸的特点，设计具有pH值响应性的聚电解质多层膜，利用层层自组装技术组装得到多层膜，并用光敏交联剂进行共价交联，改变组装层数、聚丙烯酸（PAA）分子量、聚阳离子组装浓度和种类等组装条件，分析多层膜表面Zeta电位随pH值变化的趋势。结果表明：PAA分子量和聚阳离子种类对多层膜的等电点影响最为显著；优化组装条件后所获得的(PAA/PAH)5、(PAA/QCS)5和(PAA/BPEI)5多层膜均在酸性条件下收缩，在pH值74条件下膨胀；(PAA/PAH)5和(PAA/BPEI)5多层膜均在pH值50时高效杀菌，在pH值74时可有效阻粘，保持表面不被细菌污染。研究获得了多层膜结构与pH响应性能的构效关系规律，为安全、高效和智能的抗菌材料的设计提供新的思路。
