Description

technical field [0001] The invention relates to a dinitrogen monomer, a diamine monomer, polyimide and modified polyimide. Background technique [0002] Generally speaking, polyimide (PI) is a polymer material obtained by polycondensation reaction of diamine monomer and dianhydride monomer. Polyimide contains imide group (imidegroup), can be divided into aliphatic (aliphatic) and aromatic (aromatlc) two categories. As far as aromatic polyimide is concerned, it has good chemical resistance, mechanical properties and thermal stability (thermal stability), so it has been widely used in semiconductor industry, optoelectronic industry, aerospace materials, biomedical materials, automobiles Industry, communication materials, machinery industry and film industry. Polyimide is also used in semiconductor substrates and packaging materials because of its excellent electrical properties, and has become an indispensable material for cutting-edge technology industries. [0003] So far...
