摘　　要：以柠檬酸(CA)和乙二胺(EDA)为原料,采用一步微波法制备了强荧光碳点(CD)。首次采用低毒性植酸(PA)催化ε-己内酯(ε-CL)开环聚合成功制备出生物可降解性聚己内酯碳点杂化材料(PCL@CD),并以不同质量比例的PCL@CD和纯PCL通过静电纺丝获得荧光可降解多功能纤维(SF)。通过对SF进行形态和性能表征,结果表明PCL@CD赋予了SF优异的光学性能和良好的亲水性。最后将由还原法制备出的银纳米颗粒浸入SF中获得抗菌纤维(Ag-SF),抗菌测试表明Ag-SF对大肠杆菌和金黄色葡萄球菌具有良好的抗菌性能。Citric acid(CA)and ethanediamine(EDA)were used as raw materials to prepare strong fluorescent carbon dots(CDs)by one-step microwave method.For the first time,low-toxic phytic acid(PA)was used to catalyze the ring-opening polymerization ofε-caprolactone(ε-CL)to successfully prepare biodegradable polycaprolactone carbon dot hybrid materials(PCL@CDs),and PCL@CDs and pure PCL(M w≈80.0 kDa)were used in different mass ratios by electrospinning to obtain fluorescent degradable multifunctional fibers(SFs).Through the morphology and performance characterization of SFs,the results show that the addition of PCL@CDs gives SFs excellent optical properties and good hydrophilicity.Finally,the silver nanoparticles prepared by the reduction method are immersed in SFs to obtain antibacterial fibers(Ag-SFs).The antibacterial test shows that Ag-SFs has good antibacterial properties against E.Coli and S.aureus.
