Hybrid antibacterial nanocomposites based on the vermiculite/zinc oxide - chlorhexidine
Original language description
The hybrid nanocomposite materials based on the vermiculite/zinc oxide - chlorhexidine were prepared in two steps. In the first step the vermiculite/zinc oxide (V/ZnO) nanocomposite was prepared by the mechanochemical method followed by a heat treatment at 650oC for 90 min. In the second step the chlorhexidine dihydrochloride (CH) was intercalated to the V/ZnO nanocomposite in weight ratio 1:1, 1:2, 1:4, 2:1 and 4:1 (wt%) thereby V/ZnO-CH nanocomposites were prepared. Phase analysis, crystal structure, phase transformation, chemical composition and particle size of the prepared hybrid nanocomposite materials were investigated by X-ray diffraction (XRD), energy dispersive X-ray fluorescence spectroscopy (XRF), carbon phase analysis, Fourier transforms infrared spectroscopy (FTIR) and particle size analyzer (PSD). The best antibacterial activity of hybrid nanocomposite materials was investigated on Gram negative (E. coli, P. aeruginos.) and the Gram positive (S. aureus, E. faecalis) bacterial strain and against yeast Candida a. by finding the minimum inhibitory concentration (MIC). The hybrid nanocomposite materials exhibit high antibacterial activity after 30 minutes with a long-lasting effect persisting up to 5 days. Dependence of the ZnO and CH concentration in vermiculite structure on the antibacterial activity was observed.
