This study aims to use natural rubber and silk sericin protein as matrix to construct antibacterial composite materials and analyze their structure and properties. Firstly, methanol and n-hexane were used to activate the surface of natural rubber, making it a better matrix. Then, natural rubber-polybutyl acrylate and natural rubber-grafted polyvinyl alcohol were used as cross-linking agents to incorporate silk sericin protein into the natural rubber matrix to prepare antibacterial composite materials. Next, scanning electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction and other technologies were used to characterize the prepared antibacterial composite materials. The results showed that silk sericin protein was successfully incorporated into the natural rubber matrix, and the composite materials had good antibacterial properties. Finally, the mechanical properties and antibacterial properties of the prepared antibacterial composite materials were tested. The results showed that natural rubber/silk sericin protein antibacterial composite materials had excellent mechanical properties and good antibacterial properties, and had good application prospects. 【Key words】natural rubber; silk sericin protein; antibacterial composite material; preparation; structure; property
