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.aureus were tested primarily.The effects of quaternary degrees on the antimicrobial property of QPEI/SiO2 were examined.The experiment results indicate that QPEI/SiO2 has a very strong antimicrobial ability.The antimicrobial ratio to E.Coli reached to 100% and to S.aureus can be closed to 100% when it is contacting with bacterium suspension of 1×109 CFU/mL under the conditions of a dose of 15 g/L.The higher the cationic degree is,the better the antimicrobial activity is.The measured results of enzyme activitiy show that the antimicrobial mechanism of QPEI/SiO2 is based on a sterilizing bacterium process.
