Preparation of ZnFe2O4/ZnO/PMMA composition with antibacterial properties and low toxicity

Abstract

In present work, the possibility of obtaining ZnFe2O4/ZnO nanoparticles by electric explosion of zinc and iron wires in an oxygen-containing atmosphere is shown. Based on the obtained nanoparticles and polymethyl methacrylate, ZnFe2O4/ZnO/PMMA composite was obtained, containing from 0.5 to 10 wt. % of nanoparticles. The composite film suppressed the viability of E. coli bacteria with an efficiency of 99.99 %, which is due to the generation of reactive oxygen species. The synthesized composite material with high antibacterial activity is promising for the production of antimicrobial materials for medicine for a long time.
