Zinc oxide nanoparticles with surface modified by degradation of capping polymers in situ during microwave synthesis

Popis výsledku v původním jazyce

Abstract Surface modified zinc oxide nanoparticles with variable lipophilicity were prepared by the help of microwave-assisted solvothermal synthesis from mechano-chemically prepared precursor. Sodium carbonate and zinc acetate dihydrate were used as starting materials, diethylene glycol was used as a solvent, poly(ethylene glycol) and polyvinyl alcohol were used as surface capping agents. The zinc oxide was obtained during the first three minutes of reaction and its surface was further modified with prolonged time of the reaction due to degradation of polymers used as capping and stabilising agents. Scanning Electron Microscopy was employed for powder morphology evaluation. Inorganic phase structure development was characterized by means of X-ray diffraction. Nanostructured composite materials with crystallite size below 10 nm were obtained with specific surface area varying from 35 to 86 m2 g-1 according to Brunauer-Emmett-Teller analysis. The progress of degradation of adsorbed poly
