A facile approach to UV-curable super-hydrophilic polyacrylate coating film grafted on glass substrate

The super-hydrophilic polymer coating film can easily be be peeled off from a substrate with the existence of water, which is a fatal drawback in practical applications. Herein, a facile approach is proposed to prepare UV-curable super-hydrophilic polyacrylate coating film that is chemically grafted on the surface of γ-methacryloxypropyltrimethoxysilane-modified glass substrate. Fourier transform infrared spectroscopy and scanning electron microscopy confirmed that the polyacrylate coating films were successfully grafted onto the glass substrate and exhibited rough micro-groove structure. The obtained polyacrylate coating film possessed super-hydrophilicity with the water contact angle close to nearly zero as well as good transmittance and antifogging property.     

Fabrication of transparent super-hydrophilic coatings with self-cleaning and anti-fogging properties by using dendritic nano-silica

In this paper, super-hydrophilic coatings were generated on glass substrates via dipping method using colloidal silica with different morphologies as the main raw materials. The coatings were characterized by transmission electron microscope (TEM), field emission scanning electron microscope (FE-SEM), water contact angle (WCA) analyzer, and atomic force microscope (AFM). The hardness, adhesion, self-cleaning and antifogging properties of the coatings were examined. It has been found that the hydrophilicity of the coating can be significantly improved by using dendritic silica nanoparticles, and the comprehensive performance of the coating is optimum when the branch length of dendritic silica nanoparticles is about 60 nm. The coatings show super-hydrophilicity (CA, 1.7°), and high transmittance (the maximum light transmittance of the coating on glass is increased by 2.2%). Moreover, the coating is very effective in eliminating fog and dirt. The hardness and the adhesion of the coating can be reached 9H and grade 0, respectively, indicating that the coatings have a good mechanical performance, which is essential for its application.

Superhydrophilic Transparent Titania Films by Supersonic Aerosol Deposition

Photocatalytic and hydrophilic TiO₂ thin‐film applications include water purification, cancer therapy, solar energy conversion, self‐cleaning devices, and antifogging windows. We demonstrate superhydrophilicity of aerosol‐deposition (AD) TiO₂ films on a glass substrate without use of a carrier solvent, thereby removing the possibility of impurity contamination. AD films exhibit high visible light transmittance (greater than 80%) and superhydrophilicity (0° contact angle) with even minimal UV‐light irradiation exposure. This AD method represents a significant step toward the realization of economically viable, functional thin films for the aforementioned applications.     

New coating materials and their preparation by radiation polymerization. III. Antifogging coating composition

Compositions for good antifogging and mar-resistant coatings were investigated. A mixture of hydrolyzed aminoalkylalkoxysilane and hydrophilic vinyl monomer was the best combination. Control of suitable viscosity for coating was carried out conveniently by irradiation. The prepolymer was coated and cured by heating to form an antifogging membrane on various base materials such as inorganic glass, CR-39 resin, and poly(methyl methacrylate). These conditions were studied in relation to some physical properties of the membrane. It was found that antifogging and mar-resistant properties were inconsistent in many cases. A possible way to achieve the best balance between the two properties is discussed.
