Synthesis and Antimicrobial Activity of Polyethylene/Chlorhexidine/Vermiculite Nanocomposites
Original language description
The set of polyethylene/clay nanocomposites with increasing amount of antimicrobial nanofiller (3, 6nand 10 wt%) was prepared by melt compounding procedure. The antimicrobial drug chlorhexidinendiacetate was loaded into natural clay mineral vermiculite and also to its monoionic sodiumnform and then these organoclay nanofillers were incorporated into polymeric matrix. The structurenof prepared organoclays and nanocomposites was studied by X-ray diffraction analysis andnFourier transforms infrared spectroscopy. Further thermal properties of polyethylene/clay nanocompositesnwere investigated by thermogravimetric analysis and the surface roughness was evaluatednby atomic force microscopy. Finally, organoclays and polyethylene/clay nanocompositesnwere tested for antimicrobial activity against bacterial strains Staphylococcus aureus, Escherichiancoli and yeast Candida albicans. Prepared samples showed a very good antimicrobial activitynwith long lasting effect. In the case of polyethylene/clay nanocomposites we observed some differencesnin antimicrobial action between two used antimicrobial nanofillers. These results suggestedngreat potential of using the polymer/clay nanocomposites in the wide range of antimicrobialnapplications.
