Description
Summary:Organically modified hybrid ceramic oxide coatings based on titanium and poly(tetraethylene glycol malonate) (PTEGM) have been prepared by sol-gel methods and the structure characterized by FT-IR spectroscopy and X-ray photoelectron spectroscopy. Results indicate that malonate units (TEGM) in PTEGM form a co-ordination bond with titanium, enabling titania to be homogeneously distributed in the polymer matrix. For molar ratios [TEGM] : [TIP] = 1 and 4 maximum crack-free thicknesses of 1.2 and 15 μm, respectively were achieved in a single dip. Ionic conductivity measurements were performed on coatings having molar ratios [TEGM] : [Ti] : [Li+] = 5 : 1.25 : 1, with lithium perchlorate as the electrolyte, giving a relatively high solid-state ionic conductivity of ca. 10−5 S cm−1 at room temperature.
