Tissue engineering has become a hot issue for skin wound healing because it can be used as an alternative treatment to traditional grafts. Nanofibrous films have been widely used due to their excellent properties. In this work, an organic/inorganic composite poly(arylene sulfide sulfone)/ZnO/graphene oxide (PASS/ZnO/GO) nanofibrous film was fabricated with the ZnO nanoparticles blending in an electrospun solution and post-treated with the GO deposition. The optimal PASS/ZnO/GO nanofibrous film was prepared by 2% ZnO nanoparticles, 3.0[Formula: see text]g/mL PASS electrospun solution, and 1% GO dispersion solution. The morphology, hydrophilicity, mechanical property, and cytotoxicity of the PASS/ZnO/GO nanofibrous film were characterized by using scanning electron microscopy, transmission electron microscope, water contact angle, tensile testing, and a Live/Dead cell staining kit. It is founded that the PASS/ZnO/GO nanofibrous film has outstanding mechanical properties and no cytotoxicity. Furthermore, the PASS/ZnO/GO nanofibrous film exhibits excellent antibacterial activity to both Escherichia coli and Staphylococcus aureus. Above all, this high mechanical property in the non-toxic and antibacterial nanofibrous film will have excellent application prospects in skin wound dressing.
