摘要
以水为溶剂,分别对4种不同浓度的聚乙烯醇(PVA)纺丝液进行静电纺丝,通过扫描电镜分析其成纤状态。选择合适的聚乙烯醇纺丝液浓度,进而配制纳米银/PVA溶液,研究其可纺性,利用EDS、红外光谱、紫外光谱表征元素分布及含量,并进行抑菌性测试。结果表明:聚乙烯醇质量分数为12%时,静电纺丝成纤状态最佳;纳米银/PVA质量比为5.33 mg/g时,纳米银/PVA纺丝液的成纤状态最佳。添加纳米银使得纤维毡的抗菌性能明显提升。
Four different concentrations of polyvinyl alcohol(PVA)spinning solutions are electrospun with water as solvent.The fiber forming state is analyzed by scanning electron microscope(SEM),and the suitable concentration of PVA solution is selected to prepare nano silver/PVA solution.The spinnability of nano silver/PVA solution is studied.The distribution and content of elements are characterized by EDS,IR and UV spectra,and the antibacterial activity is tested.The results show that when PVAis 12%,the electrospinning state is the best;when the nano silver/PVA is 5.33 mg/g.the fiber forming property of nano silver/PVA spinning solution is the best.The antibacterial properties of the fiber felt are significantly improved by adding nano silver.
