Problems solved by technology

[0008] There are no reports in the existing literature on the use of atom transfer radical polymerization to modify nanoparticles to improve the visible light transmittance and ultraviolet shielding effect of composite materials.
At the same time, optoelectronic materials used for signal transmission need to meet the requirements of low dielectric constant and dielectric loss in order to speed up transmission and reduce loss. However, the existing literature only discusses ultraviolet shielding performance or visible light transmittance, and neither Pay attention to its dielectric properties

Abstract

The invention discloses a transparent acrylic acid silicone resin nano composite material and a preparation method thereof. The transparent acrylic acid silicone resin nano composite material is prepared by adopting the steps of dissolving 100 parts of organic silicone resin containing methacryloxy at terminal group, 1 to 100 parts of photocuring monomer containing unsaturated double bond, 1 to 6part of ultraviolent photoinitiator and 0.001 to 0.6 part of polymethacrylate polymer-grafted inorganic nano particle in a polar solvent in the terms of weight, and performing free radical copolymerization reaction under the illumination of ultraviolet light to prepare the transparent acrylic acid silicone resin nano composite material. The prepared nano composite material has high visible light transmittance, excellent ultraviolet shielding property and good dielectric property. The prepared composite material has extraordinarily wide application prospect owing to the prominent integrated performances, especially in the fields in which high transparency, ultraviolet shielding and dielectric property are required. In addition, the adopted preparation method has the advantages of wide sources of raw materials, simple and controllable preparation process, and the like.

Description

technical field [0001] The invention relates to an organic-inorganic nanocomposite material and its preparation, in particular to a transparent acrylic silicone resin nanocomposite material and its preparation method. Background technique [0002] Transparent polymer-inorganic composite materials are used as basic materials for optical fibers, LED packages, lenses and flat panel displays due to their high refractive index, good dielectric properties, excellent ultraviolet shielding properties, and high visible light transmittance. Very important application value has been developed rapidly in recent years. [0003] There are mainly two methods for preparing polymer-inorganic composites: in-situ method and ex-situ method. The former is to generate nanoparticles in situ in the polymer, while the latter is to directly mix the synthesized nanoparticles with the polymer or mix the nanoparticles Mixed with monomers that will polymerize to form composite materials.
