Demands for the strong and multifunctional fiber has substantially increased in textile industry, biomedical, and biotechnological applications. This study explores to fabricate nanocomposite functional fibers by embedding highly oriented graphene oxide (GO) into the poly (vinyl alcohol) (PVA) matrix. The GO/PVA nanocomposite fibers were prepared via gel spinning and subsequent hot drawing process. The tensile strength of the produced GO/PVA nanocomposite fibers was significantly enhanced owing to the uniformly dispersed and oriented GO nanosheets. Additionally, the ultraviolet protection factor of the highly aligned GO/PVA nanocomposite fibers is about 16 times than that of the neat PVA fiber. The as-prepared GO/PVA nanocomposite fibers also exhibit significant activity against both Gram-negative and Gram-positive bacteria. This highly aligned and integrated approach suggests an effective method to prepare graphene-based nanocomposites fibers with high performances and novel functional characteristics.

在纺织工业，生物医学和生物技术应用中，对坚固多功能纤维的需求已大大增加。这项研究探索通过将高度取向的氧化石墨烯（GO）嵌入聚乙烯醇（PVA）基质中来制造纳米复合功能纤维。GO / PVA纳米复合纤维是通过凝胶纺丝和随后的热拉伸工艺制备的。由于均匀分散和定向的GO纳米片，所生产的GO / PVA纳米复合纤维的拉伸强度显着提高。此外，高度排列的GO / PVA纳米复合纤维的紫外线防护系数约为纯PVA纤维的紫外线防护系数的16倍。所制备的GO / PVA纳米复合纤维还对革兰氏阴性细菌和革兰氏阳性细菌均表现出显着的活性。
