摘　　要：由聚乙烯醇(PVA)的醋酸水溶液通过静电纺丝制得了完全水解的PVA纳米纤维。对纺丝得到的纳米纤维进行热处理后PVA纳米纤维显示出耐热水性能,并且纳米纤维非织造布的拉伸机械性能得到了大幅提高。同时纤维表面仍有亲水性,Fe_3O_4磁铁粒子通过水热合成均匀的沉积到PVA纳米纤维的表面上,制备出带有磁性的非织造布。Fully-hydrolyzed poly（vinyl alcohol）（PVA）nanofibers were electrospun from aqueous solutions of PVA in the presence of acetic acid.A continuous spinning of uniform PVA nanofibers proceeded by the addition of acetic acid due to the changes of electronic conductivity and surface tension of aqueous solution of PVA.After the thermal treatment of asspun nanofibers,PVA nanofibers were achieved to resist disintegration in contact with hot water and the tensile mechanical property of nanofiber non-wovens was greatly improved.Magnetite was deposited uniformly onto the hydrophilic surface of PVA nanofibers and resulted in novel magnetic non-wovens.
