Abstract

The invention belongs to the field of organic/inorganic hybrid materials, and discloses a thermoset polybenzoxazine-polyimide resin composite/mesoporous molecular sieve hybrid material, which consists of a thermoset polybenzoxazine-polyimide resin composite and a mesoporous molecular sieve, wherein the mesoporous molecular sieve mass content of the hybrid material is 0.5 to 15 percent. Through a preparation method of the invention, the polybenzoxazine-polyimide resin composite/mesoporous molecular sieve hybrid material with a good interface structure and high comprehensive performance can be obtained. Compared with resin composites, the hybrid material not only maintains the heat resistance of substrate resin materials, but also has higher room-temperature storage modulus and lower dielectric constant so as to broaden the application prospect of the polybenzoxazine-polyimide resin composite in the fields of electrical engineering, electronics, information, military, aviation, aerospace and the like.

Description

technical field [0001] The invention belongs to the field of organic / inorganic hybrid materials, in particular to a novel thermosetting polybenzoxazine-polyimide resin composition / mesoporous molecular sieve hybrid material and a preparation method thereof. Background technique [0002] Polybenzoxazine is a new type of thermosetting resin developed on the basis of traditional phenolic resins. It takes benzoxazine as an intermediate and undergoes ring-opening polymerization under the action of heating or a catalyst to form Nitrogen-containing polymers with a network structure similar to phenolic resins. Polybenzoxazine not only maintains the advantages of traditional phenolic resins such as high temperature resistance, good electrical and mechanical properties, and cheap raw materials, but also improves the shortcomings of phenolic resins, such as small molecule release during curing, strong acid catalyzed corrosion equipment In addition, it also has the characteristics of lo...
