PVA-Cu(Ⅱ)、PVA-Hg(Ⅱ)配合物功能纤维的制备及抗菌性能研究

Preparation of PVA-Cu(Ⅱ)and PVA-Hg(Ⅱ)complex fibers and their antibacterial property

将金属离子Cu(Ⅱ)、Hg(Ⅱ)与聚乙烯醇(PVA)纤维进行配位反应,制备PVA-Cu(Ⅱ)、PVA-Hg(Ⅱ)金属配合物纤维,通过改变反应体系的温度、pH值和反应时间,得出了制备配合物纤维的最佳工艺条件为pH=11、温度为40℃反应时间为1h,金属离子的含量最高。将制备的纤维进行了抗菌测试,研究了PVA-Cu(Ⅱ)、PVA-Hg(Ⅱ)金属配合物纤维的抗菌性能。结果表明,根据最佳工艺参数制备的纤维具有一定的抗菌效果。

PVA-Cu（Ⅱ）and PVA-Hg（Ⅱ）complex fibers were prepared by coordination reaction with Cu（Ⅱ）,Hg（Ⅱ）and PVA.The optimal reaction conditions were that pH=11,reaction temperature at 40℃ and 1hour.The antibacterial property of PVA-Cu（Ⅱ）and PVA-Hg（Ⅱ）complex fibers were all be evaluated.Results indicated the prepared fibers had better antibacterial property.
