| Abstract: | Chitosan is a promising candidate as an antimicrobial agent in food packaging materials and biomaterials due to its biocompatibility, biodegradability, non‐toxicity and biocidal activity. In this study, chitosan derivatives, α‐(5,5‐dimethyl hydantoin amino)‐chitosan (CS‐HDH), were synthesized. The CS‐HDH nanospheres were prepared by ionic gelation method and characterized by SEM, FT‐IR, XRD, and TGA‐DTG. The prepared novel chitosan nanospheres in the range of 200–300 nm had good dispersibility. The CS‐HDH nanospheres were used to prepare antibacterial PVA hybrid films by solvent evaporation technique. The surface morphology and thermal property of hybrid films were measured by SEM, AFM, and TGA‐DTG. The results of antibacterial test showed that the hybrid film with 1.24 × 1018 atoms/cm2 of active chlorine exhibited excellent antibacterial properties against Staphylococcus aureus and Escherichia coli O157:H7, and all of bacteria could be inactivated within 5 min. © 2016 Wiley Periodicals, Inc.
