Graphene oxide (GO) nanosheets as great nanofiller have been utilized for the enhancement of a polymer matrix. In this work, polymeric N‐halamine poly[5,5‐dimethyl‐3‐(3′‐triethoxysilylpropyl)hydantoin] (PSPH) was covalently grafted onto GO, which was denoted as GO‐PSPH. The chlorinated GO‐PSPH (GP‐Cl) was then mixed with poly (vinyl alcohol) (PVA) solution to obtain the PVA/GP‐Cl hybrid films. The as‐prepared hybrid films were characterized by scanning electron microscopy (SEM) and Fourier transform infrared (FT‐IR) spectra. Compared with PVA film, the addition of GP‐Cl into PVA matrix endowed the film with enhanced thermal and mechanical properties, and the crystallinity, tensile strength, and Young's modulus increased by 45, 21, and 246%, respectively. It can be deduced that the interfacial interaction between PVA matrix and GP‐Cl nanosheets was the crucial factor for the physical enhancement. Furthermore, the synergistic effect between GO and polymeric N‐halamine greatly improved the antibacterial activities of the hybrid films with 3.95 logs reduction of Staphylococcus aureus and 4.53 logs reduction of Escherichia coli O157:H7 with 30 min of contact time, respectively. © 2019 Wiley Periodicals, Inc.
