OPEN VESSEL MICROWAVE-ASSISTED SYNTHESIS OF Ag/ZnO HYBRID FILLERS WITH ANTIBACTERIAL ACTIVITY

Popis výsledku v původním jazyce

A domestic microwave oven was adapted for development of a fast one-pot microwave assisted solvothermal synthesis with the aim of preparation of hybrid Ag/ZnO fillers for prospective medical application. Various hierarchical structures were synthesized in a very simple manner in low-temperature green process. Zinc acetate and silver nitrate were used as sources of Zn2+ and Ag+. Polyvinylpyrrolidone (PVP), glucose, hexamethylenetetramine (HMTA), and aqueous ammonia were used as various reduction and precipitation agents in water solution in this explorative study. The scanning electron microscopy (SEM) and X-ray diffraction (XRD) characterization reveal hexagonal structure of ZnO particles with the size up to 1?m combined with silver spheres with the diameter about 200 nm. In order to evaluate application potential of prepared materials zone diffusion test was used testing of their antibacterial activity. PVA films containing 5 wt.% of various Ag/ZnO hybrid fillers were prepared by solu
