1results about How to "Improve light guide efficiency" patented technology

The application provides a high-efficiency light-guiding film material, and relates to the technical field of materials.The material is prepared from the following raw materials in percentage by mass: cellulose nanocrystal support film 45-70%; photo-curable resin composition 30-55%; wherein the photo-curable resin composition is prepared from the following raw materials in parts by weight: aromatic polyurethane acrylate oligomer 60-80 parts, active diluent monomer 20-40 parts, photoinitiator 0.5-3 parts, accelerator or leveling agent 0.1-0.5 parts.The high-efficiency light-guiding film material is prepared by compounding cellulose nanocrystal (CNC) support film and photo-curable resin composition, significantly reduces the scattering and reflection loss of light at the interface, realizes high transparency and high light-guiding efficiency in the visible light region, avoids absorption or reflection interference on visible light, and further ensures light transmission.
