The Addition of TiO₂ Ratios in SiO₂–TiO₂ Nanocomposite by Sonochemical Process for the Enhancement in Self-cleaning Property

Abstract This research aims to study self-cleaning property for removing atmosphere pollutants on the substrate surface. Thus, modification of nanocomposite material is an important challenge solving organic various surfaces. Nanocomposite in this work focused SiO 2 -TiO based metal oxide materials that synthesized by sonochemical process with precursors tetraethyl orthosilicate (TEOS) and titanium isopropoxide (TTIP). The crucial parameter different amount ratios matrix related improvement structural properties. Si:Ti precursor were varied at 1:0.1, 1:0.5, 1:1 0:1 (pure TiO ). phase powder was detected X-ray diffraction technique (XRD). Chemical bonding structure analysed Fourier transform infrared spectrophotometer (FTIR). Surface morphology monitored field emission scanning electron microscope (FE-SEM). nanocomposites form composite spherical particles decorated its After that, products mixed TES 40 WN solution deposited glass slides spray coating hydrophilic contact angle method. film reduced increase Ti ratio resulting development surface substrate. influence would be improved hydroxyl groups corresponding Ti–O–Si linkages. For property, showed optimized condition decreasing 28.97 degree 60 min after UVA irradiation.
