Abstract Graphene-based film is a promising candidate for many applications including biomedical and environmental fields. In this work, a novel type of composite film based on graphene oxide (GO) sheets, silver nanoparticles (AgNPs), and carbon fiber (CF) has been prepared by a facile method using cast coating process followed a thermal reduction treatment. GO provided a substrate to spread AgNPs uniformly, which endowed the composite film with well antibacterial abilities against gram-negative and gram-positive bacteria. Meanwhile, failure stress of the films showed an enhancement of over 80% due to the introduction of CF.

具有增强机械性能的石墨烯基抗菌薄膜

摘要 石墨烯基薄膜是包括生物医学和环境领域在内的许多应用的有前途的候选者。在这项工作中，一种基于氧化石墨烯 (GO) 片、银纳米粒子 (AgNPs) 和碳纤维 (CF) 的新型复合膜已通过使用流延涂层工艺和热还原处理的简便方法制备。GO为AgNPs的均匀分布提供了基质，使复合膜对革兰氏阴性菌和革兰氏阳性菌具有良好的抗菌能力。同时，由于CF的引入，薄膜的失效应力提高了80%以上。
