Abstract: Chitin/starch/rubber composites were prepared by emulsion blending of natural rubber and the bifunctional filler of regenerated chitin/oxidized starch as filler.The structure of bifunctional filler and composites were studied.The mechanical and antibacterial properties of composites were also investigated.The results showed that after modifying by regenerated chitin,interaction between oxidized starch and natural rubber was increased.The mechanical strength of natural rubber was also improved and natural rubber was endowed antibacterial properties.When the charging amount of bifunctional filler was 10wt%,the composite had the best mechanical properties.The 300% fixed tensile force was 2.3MPa,the tensile strength was 7.0MPa and fracture elongation was 1600%.The composites also showed a certain antibacterial properties to E.coli and S.aureus.
