A method for preparing hierarchical structure polyimide material by hydrothermal polymerization

Abstract

The present invention belongs to the technical field of polyimide material synthesis, and is specifically a method for preparing hierarchical polyimide by hydrothermal polymerization. The present invention provides a method for preparing hierarchical polyimide materials using an aqueous phase system as a solution, which overcomes the problems of high cost and environmental pollution of preparing hierarchical polyimide materials using polar aprotic solvents such as N-methyl-2-pyrrolidone, dimethylformamide, dimethylacetamide, etc. as solutions in the prior art. The preparation method provided by the present invention is green and environmentally friendly, low in cost, simple in post-processing, and the prepared hierarchical polyimide material has good crystallinity and high active site utilization, and can be further applied to the fields of electrode materials such as high-strength structural materials and lithium-ion batteries and supercapacitors, and has a wide range of practical application value.
