摘　　要：为有效控制人体发生严重创伤时出血,减少伤口感染概率,研制了具有抗菌止血功能的弹性绷带。以聚丙烯(PP)纺粘弹性非织造材料为基材,对其进行聚乙烯醇(PVA)亲水改性和壳聚糖(CH)接枝改性处理,得到具有抗菌和止血双重功能的PP-PVA-CH弹性非织造材料,并对改性前后试样的性能进行了对比分析。结果表明:PVA和CH成功负载在非织造材料表面,且改性对材料主体结晶结构没有影响;PP-PVA-CH的最大拉伸断裂强力和断裂伸长率分别是PP的1.40和1.24倍,PP-PVA-CH的弹性回复率为88%;改性后试样的接触角有效降低,去离子水和人工合成血液的扩散面积分别是PP的13.0和12.9倍;PP-PVA-CH对大肠杆菌和金黄色葡萄球菌的抑菌率均大于99.0%。In emergencies,surgical operations and military conflicts,the human body may suffer from severe trauma resulting in massive bleeding.In order to effectively control bleeding and reduce the chance of wound infection,an elastic bandage with antibacterial hemostatic functions was developed.Polypropylene(PP)spunbonded elastic nonwovens were chosen as the base materials and treated with hydrophilic modification of polyvinyl alcohol(PVA)and grafting modification of chitosan(CH)to obtain PP-PVA-CH elastic nonwovens with both functions of antibacterial and hemostasis.The properties of the samples before and after modification were analyzed.The results show that PVA and CH were successfully loaded on the surface of nonwovens without affecting the main crystal structures.The maximum tensile breaking strength and elongation at break of PP-PVA-CH were 1.40 and 1.24 times higher than that of PP,and elastic recovery rate of PP-PVA-CH was 88%.Contact angle of the modified sample decreased effectively,and the diffusion areas of deionized water and synthetic blood were 13.0 and 12.9 times that of PP elastic nonwovens,respectively.Antibacterial rate of PP-PVA-CH elastic nonwovens against E.coli and S.aureus were found higher than 99.0%.
