The information about the process of forming thin titanium oxide films by pulling out the substrates from the titanium tetraisoproproxide alcohol solution has been presented. It has been shown that the deposited titanium oxide contains a continuous film and the globules of titanium oxide formed on its surface. It has been revealed that the density and the height of the globules depend on the rate of pulling out the substrate from the solution and the relative humidity in the chamber, and the thickness of the continuous film of titanium oxide is a relatively constant value.

Unique properties of carbon nanotubes (CNTs) make them promising for creating composite electrode materials, based on the combination of CNTs with transition metals oxides. The influence of the RF plasma functionalization on vertically aligned carbon nanotubes arrays structural characteristics has been studied using the combinational scattering spectroscopy. At a higher partial argon consumption and low total gases expenditure the processing time pull with nickel oxide distribution, deposited by the SILAR method, upon the nanotubes has been determined. By means of the scanning electron microscopy it has been shown that an increase of the functionalization time from 30 to 1200 seconds permits to increase the depth of CNT surface coverage by the nickel oxide layer from 300 nm to 2.5 μm. The resultant composite structures can be used as a supercapacitor electrode.

The results of the investigated sensory properties of the zinc oxide films (ZnO), obtained by the sol-gel technology, have been presented. It has been shown that the variation of the films resistance during the repeated thermal cycling is in the temperature range of 50 - 500 °C, under conditions of the different relative humidity it is (7.5 - 90%) when exposed to the nitrogen oxides (NO and NO).
