Abstract

The invention relates to a high-dielectric constant composite material. Bismaleimide resin monomer, maleic anhydride, octamethylcyclotetrasiloxane, pentaerythritol tetraacrylate, phenoxy resin, iso-tridecanol polyoxyethylene ether, polycaprolactam resin, filler and ethylene glycol are taken as materials, a resin-based compound system is prepared; the resin-based compound system is then put into a mold and hot-pressed, and thereby the high-dielectric constant composite material is obtained. The high-dielectric constant composite material has excellent mechanical property and heat resistance, and the development and application of high-dielectric constant composite materials can be met.

Description

technical field [0001] The invention belongs to the technical field of novel composite materials, and in particular relates to a high dielectric constant composite material. Background technique [0002] Inorganic particles of high dielectric constant polymer composites are mainly divided into three categories: ceramics, carbon and metal particles. A dielectric is any substance that can establish polarization inside a dielectric material under an electric field. Power devices are an integral part of electrical energy conversion, and their performance directly affects the efficiency of energy conversion. Although the functions of portable electronic products are becoming more and more powerful, the shorter and shorter usage time has become an important bottleneck. From the invention of integrated circuits in 1959 to the present, the integration level of integrated circuits in the semiconductor industry has grown at a rate of 25% to 30% per year. In the 1970s and 1980s, it c...
