Peroxide pre-vulcanized natural rubber/silk fibroin antibacterial composite: its preparation and properties

A novel composite possessing antibacterial property was prepared by peroxide pre-vulcanized natural rubber (PVNR) and ternary-mixture dissolved silk fibroin (SF) through latex compounding technique. The relative property of the latex and the sheets was performed and analyzed. The results showed that SF maintains the stability of latex, which is important to latex system. After drying and forming sheets, the compatibility between PVNR and SF is very excellent, and SF enhances the tensile strength of the matrix at a certain extent. Moreover the thermal stability and viscoelasticity of PVNR matrix are not greatly affected. In addition, it can be predicted from infrared spectra that the antibacterial property of SF may relate with the amied I structure and further research will continue.
