Antimicrobial graphene polymer (PVK-GO) nanocomposite films

摘要

The first report on the fabrication and application of a nanocomposite containing poly-N-vinyl carbazole (PVK) polymer and graphene oxide (GO) as an antimicrobial film was demonstrated. The antimicrobial film was 90% more effective in preventing bacterial colonization relative to the unmodified surface. More importantly, the nanocomposite thin film showed higher bacterial toxicity than pure GO-modifled surface. Biofilm formation on conducting materials (metal, metal alloys, metal oxides, and electrodes) has emerged as a significant problem in the long-term use of bioimplants, biosensors, and marine and industrial apparatus.
