Abstract
U ovom radu je eksperimentalno ispitan utjecaj modifikacije staklenih podloga različitih geometrija na morfologiju ZnO slojeva, pokrivenost površine i prionjivost prevlake. Prevlake su dobivene metodom taloženja iz otopine. Staklene podloge su hidrolizirane ili žarene i uronjene u alkoholnu otopinu cinkova acetata dihidrata u metanolu te stavljene u sušionik na temperaturu od 55 °C i vrijeme 41 – 44 h. Dobivene prevlake su uglavnom cvjetićaste morfologije. Hidroliza se pokazala uspješnom u dobivanju homogenih i dobro prianjajućih prevlaka, dok se žarenje pokazalo lošim. Rezultati rendgenske difrakcijske analize su pokazali da je nastala karakteristična struktura slojevitih baznih cinkovih soli (LBZS). S obzirom da je infracrvenom spektroskopijom utvrđena prisutnost hidroksilnih i acetatnih skupina, nastala prevlaka je vjerojatno cinkov hidroksiacetat. Kalciniranjem uzoraka na 400 °C uspješno je provedena pretvorba cinkovog hidroksiacetata u oksid.
Abstract (english)
In this paper, the influence of modification of glass substrates with varying geometries on morphology of ZnO coatings, surface coverage and adhesion of coatings was experimentally tested. Coatings were prepared by chemical bath deposition method. Glass substrates were modified by hydrolysis or annealing, immersed in alcoholic solution of zinc acetate dihydrate in methanol and put in a drying oven at temperature of 55 °C and time of 41 – 44 h. The deposited coatings mostly had flower-like morphology. Hydrolysis of glass surface resulted in homogeneous and adherent coatings, while calcination proved to be a poor surface modification. X-ray diffraction analysis showed that characteristic structure of layered basic zinc salts (LBZS) was formed. Considering that infrared spectroscopy had determined presence of hydroxyl and acetate groupes, prepared coatings were presumably zinc hydroxy acetate. Zinc hydroxy acetate was successfully transformed into zinc oxide by calcinating samples at 400 °C.
