Fluorinated-Triazole-Modified ZnO and Its Application in Marine Antifouling
نویسندگان
چکیده
The accumulation of marine biological growth has irreversible negative effects on shipping and coastal fisheries. In this paper, a new antibacterial nanofiller—triazole fluoroaromatic hydrocarbon?modified nano?zinc oxide (ZnO?APTES?TRF)—was prepared by Cu(I)?catalyzed azide–alkyne click chemical reaction. modification nano?ZnO with triazole ring hydrocarbons were testified FT?IR, XPS, EDS. grafting rate ZnO?APTES?TRF can reach 32.38%, which was verified the TGA test. mixed zinc acrylate resin to produce low surface energy antifouling coating water contact angle 106°. bactericidal against Escherichia coli, Staphylococcus aureus, Pseudoalteromonas sp. more than 98% due synergistic effect fluorine. 120?day experiment shows that ZnO?APTES?TRF/ZA is expected be widely used in field antifouling.

The surface properties of TiO2-PVDF nanocomposite membranes were investigated by incorporating different chemically modified TiO2 nanoparticles into the poly (vinylidene fluoride) (PVDF) matrix. The nanocomposite membranes were prepared via dual coagulation bath diffusion and the induced phase inversion method. The membrane surface morphologies were investigated by using SEM and AFM and related...
