Özet

Hybrid organic-inorganic, photocatalytic nanocomposite coatings that containing novel 1,2,4-triazole based Cu(II) and Zn(II) phthalocyanines modified TiO2 nanoparticles were developed with the sol-gel pro-cess. Tetraethyl orthosilicate, 3-(glycidyloxypropyl)triethoxysilane and triethoxymethylsilane were used for hybrid polymer network. The phthalocyanines modified TiO2 nanoparticles prepared by the sol-gel method were added to the obtained hybrid polymer network at of 10%, 25%, and 50%, and the glass sub-strates were coated the obtained coating solutions by spray method. The photocatalytic activity, optical characterization, morphological and mechanical properties of the coated glass surfaces were examined. The adhesions of the obtained films were classified as 5B, and the pencil and newton hardness were > 9H and 2.6 N, respectively. This study acquired photocatalytic hybrid nanocomposite films that are highly transparent and do not have color changes and that also exhibit hight photocatalytic activitiy. (C) 2021 Elsevier B.V.
