抄録

A novel Zn(II)-Poly(acrylonitrile-co-silk fibroin peptide) complex was synthesized by copolymerization of acrylonitrile and a new complex macromonomer consisting of Zn ion and modified silk fibroin peptide by acryloyl chloride with vinyl groups. we examined effects of using distilled water and diluted hydrochloric acid as precipitant for the obtained resulting complex solution in the termination stage of copolymerization on the content of Zn(II) of copolymers. And the copolymer complexes containing Zn ions of difference content were obtained. By the typical IR peaks of pure poly(acrylonitrile-co-silk fibroin peptide) and its complexes, the ligand coordination occurs mainly through oxygen atom and nitrogen atom from the amide carbonyl group and no complex formation between the CN group and Zn ion were presumed. The other, by absorbing various metal ions on pure copolymers, several copolymer metal complexes could be also obtained. However, the results eluting Zn2+ from powder of copolymer complexes by diluted HCl indicated their difference stabilities, the complex synthesized by vinyl groups had better stability than that obtained by absorbing metal ions. All copolymer complexes exhibited significant odor-removing activity. And the sample of higher content of Zn ion reveals good antibacterial activity.
