| Abstract: | A series of chitosan graft poly(acrylic acid ) superabsorbent composites which had antibacterial activity were synthesized by graft polymerization between chitosan and acrylic acid.Influences of polymerization variables,including the content of initiator,crosslinker and chitosan,neutral degree on water absorbency were studied.The antibacterial activity of the superabsorbent composites affected by different chitosan content and neutral degree was also investigated.The result showed that the polymer synthesized in the optimal reaction condition had high water absorbency and high antibacterial activity,which could absorb 684.85 times deionized water,and graft yield was 84.25%.The copolymers obtained were inhibitory to the growth of escherichia coli and staphylococcus aureus,bacteriostasis rate was 65%～75%. |
