288-16-4, Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.288-16-4, Name is Isothiazole, molecular formula is C3H3NS, introducing its new discovery.
Biocidal poly (vinyl alcohol) films incorporated with N-halamine siloxane
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 coli O157:H7 completely with concentrations of 4.57 ¡Á 107cfu and 2.70 ¡Á 107cfu within 5 and 10 min, respectively, and 99.9995% of Escherichia coli 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.
