In this study, electrospun nylon-6 spider-net like nanofiber mats containing TiO(2) nanoparticles (TiO(2) NPs) were successfully prepared. The nanofiber mats containing TiO(2) NPs were characterized by SEM, FE-SEM, TEM, XRD, TGA and EDX analyses. The results revealed that fibers in two distinct sizes (nano and subnano scale) were obtained with the addition of a small amount of TiO(2) NPs. In low TiO(2) content nanocomposite mats, these nanofiber weaves were found uniformly loaded with TiO(2) NPs on their wall. The presence of a small amount of TiO(2) NPs in nylon-6 solution was found to improve the hydrophilicity (antifouling effect), mechanical strength, antimicrobial and UV protecting ability of electrospun mats. The resultant nylon-6/TiO(2) antimicrobial spider-net like composite mat with antifouling effect may be a potential candidate for future water filter applications, and its improved mechanical strength and UV blocking ability will also make it a potential candidate for protective clothing.
在这项研究中，成功制备了含有 TiO(2) 纳米粒子（TiO(2) NPs）的尼龙-6 蜘蛛网状纳米纤维垫。通过 SEM、FE-SEM、TEM、XRD、TGA 和 EDX 分析对含有 TiO(2) NPs 的纳米纤维垫进行了表征。结果表明，加入少量 TiO(2) NPs 后，可以得到两种不同尺寸（纳米和亚纳米级）的纤维。在低 TiO(2) 含量纳米复合材料垫中，发现这些纳米纤维编织物均匀地负载在其壁上的 TiO(2) NPs。在尼龙-6 溶液中加入少量 TiO(2) NPs 可提高电纺垫的亲水性（抗污效果）、机械强度、抗菌和抗紫外线能力。具有抗污效果的尼龙-6/TiO(2) 抗菌蜘蛛网状复合垫可能是未来水过滤器应用的潜在候选材料，其机械强度的提高和对紫外线的阻挡能力也使其成为防护服的潜在候选材料。
