Preparation and properties of porous P(St-MMA-AA) microsphere anti-glare film

Monodisperse nanoparticles can form two-dimensional or three-dimensional colloidal crystals with periodic ordered structure by self-assembly. They are widely application in optical devices, sensors, electronic devices and drug delivery. Photonic crystals consisting of spherical colloidal particles periodically have various properties and strong designability. Its performance and application have great research value. In order to ensure the transmittance of anti-static, anti-glare and anti-radiation (three-proof) nano-material films, the mist is often not ideal, which limits the practical application of anti-glare films. P(St-MMA-AA) microspheres with different pore sizes were prepared by adjusting the content of acrylic acid. The effects of particle size, concentration and pore structure of microspheres on the transmittance and mist of colloidal crystal coatings were investigated. It was found that increasing the pore structure of microspheres could improve the transmittance of colloidal crystal coatings and keep the mist constant. The experimental results show that the porous colloidal film can reach the standard transmittance when the concentration is 0.01%. It has good anti-glare and acid resistance. The application of porous nanoparticles in high transmittance anti-glare coating is further broadened. This colloidal crystal coating deposits polymer microspheres on the substrate by self-assembly. The preparation method has the advantages of simple equipment, good repeatability, easy operation, non-toxicity and easy synthesis, low cost of raw materials, high yield and environmental friendliness.
