Photocatalytic treatments on dental mirror surfaces using hydrolysis of titanium alkoxide

Abstract

Anatase titanium dioxide (TiO 2 ) photocatalytic thin films were directly formed on glass slide and commercial dental mirror substrate surfaces by a hydrolysis of titanium alkoxide, and the hydrophilicity, the degree of oxidizing power and the transparency of the anatase TiO 2 -coated substrate surfaces. The contact angles of water and the decomposition rates of methylene blue on the anatase TiO 2 photocatalytic thin films improved with the increasing duration of a tetraethyl orthotitanate (TEOT) hydrolysis, but they hardly changed for the longer duration. The reflectance of anatase TiO 2 photocatalytic thin films coated on glass slide substrate surfaces was higher as the duration of a TEOT hydrolysis increased. Similar tendencies concerning hydrophilicity and transparency were recognized in cases of commercial dental mirror substrate surfaces. A hydrolysis of titanium alkoxide obtained superhydrophilic and antibacterial treatments with excellent transparency on commercial dental mirror substrate surfaces.

From Nanotechnology to Nanoengineering

“…Nanoparticulate titanium dioxide (TiO 2 ) is another nanostructure used in synthesis of antimicrobial products (Chung et al 2008). This nanostructure has found more applications such as in synthesis of flame retardants (Chen and Wang 2010;Kiliaris and Papaspyrides 2010), mineral UV filter in sunscreens (Popov et al 2005;Sadrieh et al 2010) and self-cleaning products (tiles, windows and textiles) like antifogging car mirrors and dental mirror surfaces (Funakoshi and Nonami 2007;Veronovski et al 2009). Another emerging application of nanostructure is in the field of refractory technologies, for example, in the steel and cement industries (Kuznetsov et al 2010;Antonovič et al 2010).…”

Nanotechnology for Chemical Engineers

“…Besides sustained release of drugs, food additives and fragrances, explained in the field of biotechnology application, they are applied for controlled release of anticorrosion agents as well as sustained release of herbicides, insecticides, fungicides and antimicrobials. This nanostructure has found more applications such as in synthesis of flame retardants (Chen and Wang 2010; Kiliaris and Papaspyrides 2010), mineral UV filter in sunscreens (Popov et al 2005;Sadrieh et al 2010) and self-cleaning products (tiles, windows and textiles) like antifogging car mirrors and dental mirror surfaces (Funakoshi and Nonami 2007;Veronovski et al 2009). Silver nanoparticles have been extensively used in both antibacterial and biocidal fabric and agent.…”

Organization of SiO2 and TiO2 Nanoparticles into Fractal Patterns on Glass Surface for the Generation of Superhydrophilicity

“…The topic of superhydrophilicity is younger comparative to that of superhydrophobicity. The superhydrophilic surfaces are having unique properties such as fast water spreading and drying, antifogging, antifouling, etc., which are mainly useful for automobile mirror and glasses, , dental mirror, bioactive implantation, , biocompatible materials, , humidity sensor, microfluidic devices, , heat transfer enhancement, , and so on. Because of these wide varieties of applications of superhydrophilic surfaces, the topic has been drawing significant attention in recent years.…”
