Synthesis and properties of alkoxysilane-functionalized urethane oil/titania hybrid films
چکیده انگلیسی

In this study, alkoxysilane-functionalized urethane oil/titania (AFUO/titania) hybrid films were synthesized by sol–gel method. For this purpose, alkoxysilane-functionalized urethane oil (AFUO) was first produced by the reaction of 3-aminopropyltriethoxysilane (APES) and partial glyceride (PG) mixture with toluene diisocyanate (TDI). Then, this intermediate was further reacted with titanium isopropoxide (TIP) by sol–gel process in thin films applied on a glass substrate. TIP content of the hybrid films were varied in the range of 5–20 wt.% in order to investigate optimum amount of TIP in view of film properties. The characterization of the hybrid films were done by FTIR, DSC, TGA and SEM analyses. FTIR and DSC analyses indicated the existence of Ti–O–Si bond. Film properties for coating purposes such as flexibility, adhesion, hardness, water, alkali and acid resistances were determined. Hybrid composite films showed better film properties in comparison with classical urethane oil.
