“…The similarity between computed and measured thickness values for AR coatings is also confirmed by Prado et al [38], Ye et al [20] and, Han and Kim [39]. In addition, it is calculated that coating thickness increases with increasing WS (> 90) according to the relation, dc ~ WS 0.5 (R 2 =0.9942); in accordance with the thickness evolution of the dipcoated films (Theoretically at high withdrawal speeds, viscous drag forces is balanced with gravitational force in the thickness evolution) [17,40]. On the other hand for lower WS (≤ 60 mm/min), the resultant coatings must be too thin and probably more amorphous than the thicker films obtained at WS > 60 mm/min.…”

“…Removable organic templates (Pluronic F127, Triton X-100, PEG, etc.) are used in the sols as pore making agents, but these methods require high annealing temperatures, like 400-500C to remove these organic materials [8,12,17]. Another approach is to use colloidal particles dispersed in a solvent [18].…”

“…During the hydrolysis and condensation reactions, secondary products of low-molecular-weight as ethanol and water molecules are generated. These molecules must be removed from the solutions [59,60]. Much research has focused on synthesizing ceramic compounds such as TiO 2 and SiO 2 independently by the sol-gel method as well as TiO 2 -SiO 2 composites due to its low cost, operation conditions and single step doping in situ.…”

Titanium dioxide is well known for its photocatalytic properties and low toxicity, meanwhile, silicone dioxide exhibits hydrophobic and hydrophilic properties and thermal stability. The union of these two materials offers a composite material with a wide range of applications that relate directly to the combined properties. The SiO2-TiO2 composite has been synthesized through physical methods and chemical methods and, with adequate conditions, morphology, crystallinity, boundaries between SiO2-TiO2, among other properties, can be controlled. Thus, the applications of this composite are wide for surface applications, being primarily used as powder or coating. However, the available research information on this kind of composite material is still novel, therefore research in this field is still needed in order to clarify all the physical and chemical properties of the material. This review aims to encompass the available methods of synthesis of SiO2-TiO2 composite with modifiers or dopants, the application and known chemical and physical properties in surfaces such as glass, mortar and textile, including aspects for the development of this material.

“…A. Shokuhfar et al characterized the change in the optical transmittance values and surface morphologies of acid catalyzed SiO2 coatings with different TEOS/Ethanol molar ratios [18]. W. Zhang et al investigated the effect of Pluronic F-127 addition and the withdrawal rate on the optical transmittance and surface morphologies of base catalyzed SiO2 coatings [19].…”

“…The important point is to adjust the rate and limit of the reaction of precursor and this can be controlled by amount and strength of catalysts [14,15]. Although the effect of the catalysis conditions on different properties of SiO2 coatings synthesized by sol-gel process is previously studied, a thorough literature study shows that the relationship between the catalyzer types and structural, chemical and optical properties of the coatings has not been yet established in details [16][17][18][19]. For example, in a previous study we investigated the structural and optical properties of acid catalyzed SiO2 coatings [16].…”

Present study deals with the effect of acid and base catalysis on SiO2 coating properties that were synthesized by sol-gel dip coating technique. Microstructural properties of the coatings were characterized by SEM and EDS was used to determine the coating composition. Spectrophotometer has been used to measure the optical properties of the coatings. The results demonstrated that SiO2 coatings deposited by both acid and base catalysis sol-gel dip coating technique were homogeneous and well-adherent. Acid catalyzed SiO2 coatings resulted with dense and smooth surface morphologies whereas base catalyzed SiO2 coatings had nanoporous structure with nanovoids ranging between 15-30 nm. According to the optical analyses, SiO2 coatings have very high transmittance values demonstrating that they are highly transparent especially in the visible light range.
