چکیده انگلیسی
An N-halamine siloxane precursor γ-(β-hydroxyl-γ-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 coli O157:H7 completely with concentrations of 4.57 à 107cfu and 2.70 à 107cfu within 5 and 10â¯min, respectively, and 99.9995% of Escherichia coli O157:H7 could be inactivated within 5â¯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.
