Application: High-performance optical absorber comprising functionalized, non-woven, cnt sheet and texturized polymer film or texturized polymer coating and manufacturing method thereof (Patent ID: US20240045119A1)
The patent filed by Northrop Grumman Corp. describes a method for manufacturing a high-performance optical absorber using capillary force lamination (CFL). The process involves texturizing a base layer, joining a non-woven carbon nanotube (CNT) sheet as a surface layer, wetting the layers with a solvent to draw the CNT sheet into the base layer, drying the layers, and treating the resulting base layer with plasma to create the optical absorber. Additional steps include plasma-treating the surface layer, using oxygen plasma for treatment, creating specific ridge patterns on the base layer, and ensuring the CNT sheet has specific characteristics like porosity and areal density.
The method outlined in the patent involves precise steps to achieve a high-performance optical absorber, including texturizing the base layer with specific ridge patterns, joining a CNT sheet as the surface layer, and utilizing capillary force lamination with a solvent to enhance the texturization process. The use of plasma treatment, specific porosity and areal density of the CNT sheet, and the creation of functionalized surface sub-layers further contribute to the optical absorber's performance. The patent also details variations in ridge shapes, porosity levels, and index of refraction for different layers within the absorber, showcasing a comprehensive approach to manufacturing a high-quality optical absorber using innovative techniques.
