Abstract

The invention relates to a high-modulus organic-inorganic hybridized polyimide film and preparation and application thereof, in particular to the technical field of organic-inorganic hybridizing polymer materials. In particular, a polymer film in which 0.1 to 60 percent of inorganic nanometer particles are dispersed has high modulus, low shrinkage and superior physical-chemical performance, and particularly has tensile modulus which is larger than 5Gpa. Designed solvent type nanoparticle dispersion liquid can be added into a polymer composition efficiently and conveniently, and inorganic nanometer particles are uniform in size, and are stable in dispersion; the high-modulus organic-inorganic hybridized polyimide film is an organic-inorganic hybridized polymer material which has the advantages of high modulus, low shrinkage, superior chemical performance and superior electric performance.

Description

technical field [0001] The invention relates to a high-modulus organic-inorganic hybrid polyimide film and its preparation and application, in particular to the technical field of organic-inorganic hybrid polymer materials. Background technique [0002] Compared with inorganic materials, organic polymer materials have good processability, better chemical resistance, and better dielectric properties, but have a larger coefficient of thermal expansion. In contrast, inorganic materials have excellent heat resistance and stability, but are difficult to shape. Organic-inorganic hybrid materials use inorganic nanoparticles to compound at the nanometer scale, which is currently the most effective method and means in the field of optoelectronic materials. [0003] As a high-performance aromatic polymer, polyimide material can be used in various applications such as plastics, films, solutions, etc. It has excellent high and low temperature stability, and exhibits excellent physical,...
