摘　　要：为赋予超高分子量聚乙烯织物舒适和抑菌功能,采用多巴胺/聚乙烯亚胺交联共聚涂覆和铜离子配位制备具有亲水及抑菌功能的超高分子量聚乙烯织物(UHMWPE-PDA/PEI-Cu),使用扫描电子显微镜、X射线衍射、傅立叶红外光谱和X射线光电子能谱等对UHMWPE-PDA/PEI-Cu织物的微观形貌结构和化学成分进行表征,并评价了UHMWPE-PDA/PEI-Cu织物对细菌的抗菌活性。结果表明,培养18 h后,UHMWPE-PDA/PEI-Cu织物对大肠杆菌和金黄葡萄球菌的抑菌率均大于99%,且与未改性的样品(UHMWPE)相比,UHMWPE-PDA/PEI-Cu织物的水接触角显著减小,其舒适性得到大幅改善。In order to develop an ultra-high molecular weight polyethylene(UHMWPE)fabric with comfort and antibacterial properties,an UHMWPE fabric with hydrophilic and antibacterial functions was prepared by means of cross-linked copolymer coating of dopamine/polyethyleneimine and copper ion coordination.The microscopic morphology and chemical composition of UHMWPE-PDA/PEI-Cu fabric were characterized by SEM,XRD,ATR-FTIR and XPS.The antibacterial activity of the UHMWPE-PDA/PEI-Cu fabric against bacteria was tested.The results showed that after 18h of co-culture,the antibacterial rates of the UHMWPE-PDA/PEI-Cu fabric against E.coli and S.aureus were greater than 99%.Compared with the unmodified samples(UHMWPE),the water contact angle of the UHMWPE-PDA/PEI-Cu fabric was significantly decreased,while its comfort was greatly improved.
