This article is connected with the preparation of anticorrosion coatings through study of influence of POSS compounds on the rheological properties of various formulations. POSS compounds were used also for the preparation of protective coatings for electronic boards. Thickness sensitive spectrally selective (TSSS) coatings should be capable of absorbing high amounts of solar energy, i.e. they should exhibit high solar absorptivity. However, due to their sensitivity to thickness, it is extremely difficult to prepare uniform, smooth and thin coatings with dense distribution. In our study, we prepared black TSSS paints at various PVC ratios by using a pigment that was treated with trisilanol POSS dispersants. Various POSS dispersants were used for pigment treatment in order to determine the influence of POSS structure on the rheological behavior of liquid paints and the solar absorptivity of applied coatings. Liquid paints were prepared at various PVC ratios in order to examine the effect of pigment loading on the rheological behavior of the paint. The rheological properties were correlated to the solar absorptivity of coatings applied on the substrate. The results revealed that POSS dispersants enable the preparation of dispersions with particularly high pigment loadings (above PVC = 51), which still exhibit liquid-like viscoelastic behavior and are sufficiently flowable to enable proper leveling, uniform distribution of pigment particles inside dry coating and, therefore, excellent solar absorptivity.

This article reports detailed analysis of IR spectroscopic characterisation of sol-gel based electrolytes for electrochromic devices. Despite the fact that the final application of material is different, the basic processes of solvolysis-hydrolysis and condensation of sol-gel structures are the same. Therefore, important information can be gathered also from the point of view of sol-gel processes during formation of protective coatings.
