Fabrication of Transparent Super-hydrophilic Coatings with Self-cleaning and Anti-fogging Properties by Using Dendritic Nano-Silica

Self-cleaning coatings are getting tremendous attention from both the academic interest and industrial communities. Among the two kinks of self-cleaning coatings, which are super-hydrophobic and super-hydrophilic coatings, the super-hydrophilic self-cleaning coating comprised of TiO2/doped-TiO2has four unique features when exposed to ultraviolet (UV) light or sunlight, which are self-cleaning property, anti-bacterial properties, environmental friendly, and visible-light photocatalysts and indoor usage. And PU-TiO2self-cleaning coating produced by “grafting” method, which can accomplish stable chemical attachment between the nTiO2and the PU substrates, may potentially show an increase of the thermal properties, an increase of the amount of active sites for photo-catalysis, and a decrease in the self-degradation of the resulting polymer nanocomposite than the traditional mechanical shear method. There is a tremendous scope for the application of polyurethane-nTiO2self-cleaning coatings in industrial, health care and consumer sectors.

Self Cleaning

Manufacturing of building materials with unique properties is one of the most important key-parameters in the development of construction engineering and building materials. The development in the nanomaterials and nanotechnology can be utilized in this field. In this paper, production of eco-friendly, low water absorption and self-cleaning cement mortar reinforced with carbon nanotubes and nano-silica with different weight percentages (0.5%, 1.5%, and 2%) is performed. Results showed prominent improvement of hardness, compression strength and a decrease of water absorption and bending resistance in the reinforced cement mortars. The results show the possibility to control the mechanical properties of the cement mortars with minimal reinforcing agents provides the possibility to design these building materials for versatile applications.

Hydrophilic Coatings

Dust deposition on solar photovoltaic (PV) cell surface will significantly decrease the PV power efficiency, as the transmittance of the solar cells would be greatly decreased by the deposited dust particles. This paper aims to study the anti-dust performance of super-hydrophilic coatings for the solar PV cells with water spraying condition. The solar cell covering glass was treated to be super-hydrophilic and compared with the bare glass sample. It was found that many dust particles adhere and aggregate on the uncoated glass while the particles deposited on the super-hydrophilic glass surface are densely distributed. When the water spraying process was conducted, the dust deposition mass for the bare and the coated glass samples are both reduced obviously with the increase time of water spraying. In addtion, dust deposition mass is significantly reduced with the increase of deposition and spraying tilt angles. The self-cleaning efficiency of super-hydrophilic coating on dust deposition is 92% higher than the bare glass cases. The spectral transmittance of glass samples for all the coated cases are significantly higher than that for all the bare cases. The maximum transmittance improvement can reach 26.5% when the deposition tilt angle is 30° and the spraying tilt angle is 60°.
