Graphene-Based Antibacterial Films with Enhanced Mechanical Properties

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.
