After three years of scientific and technological research, China's optical film precision micro-replication technology has made major breakthroughs and successfully broke the monopoly of foreign technology. This was the news that the reporter learned from Hubei Provincial Department of National Defense Engineering and Hubei Institute of Aerospace Chemical Technology on the 10th. According to reports, optical thin-film precision microreplication technology is a technology that precisely coats a specific formulation resin on the surface of an optical film substrate and then forms on an engraved roller having a specially designed nano-microscopic geometric structure.
It is widely used in liquid crystal flat panel backlight module brightness enhancement film and diffusion film, road traffic sign micro prism prism reflective film, liquid crystal display protection anti-reflection film and privacy film, naked eye 3D display function film and home appliances used imitation metal brushed high-gloss film Wait. These products have high added value and large market demand. The key technologies have always been in the hands of foreign companies.
From 2014 to 2016, the Hubei Institute of Aerospace Chemical Technology undertook the “Key Technology Development and Application of Optical Thin-Film Precision Microreplication Technology†of Hubei Province's major science and technology project. It has successively carried out research on structural design, engraved resin formulation research and coating technology. Accepted by Hubei Science and Technology Agency.
Relevant person in charge of the Hubei Institute of Aerospace Chemical Technology said that they have designed special surface coating microstructures and developed a special marking coating resin formula. The anti-glare, anti-scratch or anti-static treatment on the back of the optical film marking coating has improved. The product yield rate of more than 20% has greatly improved the technological level of China's new material industry chain.
According to reports, at present, this technology has been applied in important national defense projects, and 10 invention patents have been filed.
