Abstract

The invention discloses a hydrophobic insulation layer of fluorine-containing polyacrylate as well as a preparation method and application of the hydrophobic insulation layer. The hydrophobic insulation layer is formed by coating a fluorine-containing polyacrylate solution or a fluorine-containing polyacrylate micro / nano-emulsion of fluorine-containing polyacrylate micro / nano-particles. The problems of poor film forming, adhesion and insulation properties of AF1600 and CYTOP are improved by utilizing characteristics that a main chain of fluorine-containing polyacrylate does not contain fluorine atoms, and a side chain contains methylene, ester group and other flexible groups; a perfluorinated side chain of fluorine-containing polyacrylate is also conducive to improving hydrophobicity of the insulation layer, so as to greatly increase the response time of microfluid on the surface of an electrowetting display device and accelerate a refresh rate of an electrowetting display screen.

Description

technical field [0001] The invention relates to the field of functional optoelectronic devices, and specifically relates to a hydrophobic insulating layer of fluorine-containing polyacrylate and its preparation method and application. Background technique [0002] With the development of microelectronics technology and information industry, electronic components are increasingly miniaturized and integrated, and at the same time, high dielectric materials, which are key structural materials, are used more and more. However, typical inorganic high-dielectric materials such as ceramic materials have disadvantages such as high brittleness, high processing temperature, and incompatibility with current circuit integration processing technologies. Although the dielectric constant of organic high-dielectric materials is not very high, it is easy to process, has good flexibility, light weight, low cost, and has good compatibility with organic substrates or printed circuit boards, and...
