| Abstract: | Polyethyleneimine was grafted on silica gel(PEI/SiO2) by a coupling agent,then PEI on silica gel was converted to tertiary amine with epihydrin and quaterisation followed by reaction with benzyl chloride to obtain water-insoluble antibacterial material(QPEI/SiO2).The chemical structures of the products were characterized with FTIR spectroscopy.The degree of grafting was 15.7%,the most highest quaternary degree was 1.57 mmol/g.The antibacterial characteristics and mechanisms of QPEI/SiO2 to E.Coli and S.aure... |
