Abstract
Uzorci TiO2 nanocjevčica pripremljeni su metodom anodizacije. Cilj je bio ispitati utjecaj temperature na rast ovog nanostrukturiranog sustava. Korištena je titanijeva folija, te teflonska anodizacijska ćelija, a sam proces je proveden pri tri različite temperature. Proces je praćen kroz promjenu struje u vremenu pri konstantnoj vrijednosti napona, iz čega je bilo moguće izvesti zaključke o utjecaju trajanja jetkanja na rast TiO2 nanocjevčica. Kako bi se proučila morfologija i svojstva dobivenih uzoraka i njihova međusobna razlika koristile su se metode karakterizacije pretražna elektronska mikroskopija (SEM), mikroskopija atomskih sila (AFM) i difrakcija rendgenskih zraka (XRD). Karakterizacija SEM metodom omogućila nam je uvid u promjer i debljinu cjevčica te gustoću njihove raspodjele. AFM metoda omogućila nam je proučavanje ujednačenosti i hrapavosti same površine uzoraka. Rendgenska difrakcija je potvrdila da dobivene nanocjevčice nakon termičke obrade kristaliziraju u anatas. Dobiveni rezultati ukazuju na sličnosti i razlike između tri navedena smjera priprave uzorka. Uspješnost sinteze i obrade uzoraka potvrđena je kroz prisutnost poželjnih nanocjevčica, uz pojavu drugih nanostrukturnih oblika.
Abstract (english)
The TiO2 nanotube samples were prepared by the anodization method. The goal was to examine the effect of temperature on the growth in this nanoscaled system. Titanium foil and a teflon anodizing cell were used, and the process itself was carried out at three different temperatures. The process was monitored through the change of current over time at a constant voltage value, from which it was possible to draw conclusions about the influence of etching duration on growth of the TiO2 nanotubes. In order to study the morphology and properties of the obtained samples and their mutual difference, the methods of characterization: scanning electron microscopy (SEM), atomic force microscopy (AFM) and X-ray diffraction (XRD) were used. SEM gave us an insight into the diameter and thickness of the tubes and the density of their distribution. AFM allowed us to study the uniformity and roughness of the sample surface itself. X-ray diffraction confirmed that obtained nanotubes after heat treatment were crystal structure of anatase. Obtained results point out to the differences and similarities between the three samples. The successfulness of the course of the optimisation of the synthesis and processing of the samples was confirmed by the presence of desirable nanotubes along with the appearance of other nanostructured forms.
