A stable polymer and reduced graphene oxide (rGO) is reported as antimicrobial agent with significant stability. On the way to destination, adhesive 2-chloro-3',4'-dihydroxyacetophenone (CCDP) and antimicrobial agent 1-bromododecane (C12) have been poly (dimethylaminoethyl methacrylate) (PEG-g-PDMA) [(CCDP-C12)-q-(PDMA)]. Later, this synthesized polymer functionalized rGO as an antimicrobial nanocomposite, rGO/(CCDP-C12)-q-(PDMA). To increase antimicrobial activity, silver nanoparticles (Ag NPs) were deposited onto the high surface area of rGO/(CCDP-C12)-q-(PDMA).The CCDP/C12-q-PDMA coated substrates and Ag NP-deposited rGO/(CCDP-C12)-q-(PDMA) exhibited remarkable bacterial killing efficiency against both Gram-positive S. aureus and Gram-negative E. coli. Therefore, the synthesized polymer offers merit as a potential coating material, and lower concentration compared to without applying Ag NPs. |
