摘要：
An N-halamine siloxane precursor gamma-(beta-hydroxyl-gamma-5,5-dimethylhydantoin)aminopropyltrithoxysilane (abbreviated as GHAPA) was synthesized in this study. GHAPA was mixed with PVA solution to prepare PVA/GHAPA cross linked film with an antimicrobial function. The obtained PVA/GHAPA cross linked film was characterized by TGA, DSC and XRD. Upon dilute household bleach treatment, the chlorinated PVA/GHAPA cross linked film could inactivate Staphylococcus aureus and Escherichia coll. O157:H7 completely with concentrations of 4.57 x 10(7) cfu and 2.70 x 10(7) cfu within 5 and 10 min, respectively, and 99.9995% of Escherichia coll. O157:H7 could be inactivated within 5 min. The antimicrobial results showed that the chlorinated films substantially outperformed the unchlorinated control samples. The biocidal films may serve as potential materials for food packaging and biomedical applications.
