In this work wettability and adsorption of OH- groups and H2O particles on the surface of TiO2 thin films doped with different concentration of Tb have been described. Thin films were manufactured by magnetron sputtering process. The particles were sputtered from metallic Ti-Tb target under low pressure of oxygen gas. The results of structural investigation (X-ray diffraction measurements) have shown...
Static electricity arises when two materials in contact are separated after rubbing and the speed of charge movement on surface is slow. Retained electrostatic charge can cause problems in many areas. Therefore it is very important to develop antistatic materials that would be suitable to avoid electrostatic discharges. In practise materials become charged by tribocharging. Comparable results can...
Rapid development of a new field of knowledge known as transparent electronics requires searching for new transparent materials which could be applied as Transparent Conducting Oxide - TCO and Transparent Oxide Semiconductors - TOS. The most important parameters of these materials are resistivity measured at room temperature and transparency level in the visible range of light spectrum. In this paper...
Polymer coatings were doped with low quantity, below 1.5% by weight, of metal and non-metal nanoparticles. The electrical properties, i.e. antistatic properties, volume resistance and temperature characteristics of dissipation factor tan??, were investigated. Antistatic properties were examined by charge decay measurements after corona charging, using JCI 155 apparatus. The results showed that the...
