The company’s “development and application of aerogel composite materials with light diffusion or low dielectric properties and application in 5G and optoelectronic industries (1/2) (project number: 110CE-2-01)” has achieved excellent results and successfully completed the project . The dielectric constant Dk of the developed low-dielectric electrogel, PI/aerogel and Epoxy/aerogel low-dielectric composite materials is between 1.3 and 1.8; the dielectric loss Df is about 0.003. It can be applied to infrastructure materials for 5G mobile phones such as current 5G communications, future sub-6GHz mid-range and mmWave high-end 5G(II), and 5G base station structural materials.
