Surface| Zusammenfassung: | By means of the IR-spectroscopy, thermogravimetry and differential thermal analysis a research has been made into peculiarity of thermal stimulated chemical transformation of adsorbed polydimethilsiloxan, as well as influence of surface active centre on these transformations. It shown, that the zirconium dioxide raises spalling resistance dimethylsililic groups. It was experimentally estimate, that PDMS provides stable hydrophobic properties of SiО2/PDMS nanocompound in the temperature interval 100 – 400 ºC with concentration of the PDMS 8 – 40 %. Zirconium dioxide presence increases thermal stability of hydrophobic coating (20, 40 % PDMS ) up to 500 ºС. |
