Problems solved by technology

However, these antistatic / conductive polyimide materials are mainly concentrated in the fields of preparing polyimide films, adhesive tapes, fibers, and adhesive materials; moreover, most of the existing polyimide products are binary Or ternary copolymerized polyimides are mainly used, and there are very few reports of quaternary or more copolymerized polyimides, and they are also used in soluble polyimide or polyimide adhesives, films, fibers At the same time, because its multi-component copolymerization reaction is to directly mix a variety of dianhydride monomers and a variety of diamine monomers for reaction, so that the monomers in the synthesized copolymer chain are basically free of Sequentially arranged, this causes the effect of the prepared multi-component copolymerized polyimide to be unsatisfactory, especially the various properties of its product are unstable, and the reproducibility is very poor, resulting in many polyimide products on the market cannot Meet the above anti-static / conductive performance requirements

Abstract

The invention belongs to the technical field of a macromolecular material, particularly relates to anti-static/conductive polyimide resin, and further discloses a preparation method and application ofthe anti-static/conductive polyimide resin. The anti-static/conductive polyimide resin uses ODA, PDA, DPTP, PMDA and ODPA as polymerization monomers for stepped polymerization; a macromolecular longchain five-component copolymer is formed; the termination is performed by a terminating agent; optional special nanometer materials and ultrafine filling materials are added for enhancing the resin; the prepared ODA/PDA/DPTP-PMDA/ODPA five-component copolyimide resin has the advantages of good wear resistance, heat deformation resistance and chemical resistance performance; good anti-static/conductive characteristics can be realized; the resin can be applied to the high-tech fields of special electronics, electric appliances, semiconductors, special industries and the like.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, in particular relates to an antistatic / conductive polyimide resin, and further discloses its preparation method and application. Background technique [0002] Materials are the material basis for the survival and development of human beings, and also the forerunner of social modernization and high-tech development. In the big family of materials, advanced resin-based composite materials are a bright pearl. Advanced resin-based composite materials refer to composite materials with a two-phase or more than two-phase structure, which are compounded with synthetic resin as a matrix and high-performance fibers as a reinforcing agent through a special molding process. Due to the advantages of high specific modulus, high specific strength, fatigue resistance, strong designability, and convenience for large-scale parts and integral molding, advanced resin-based composite materials have been wid...
