Description
technical field [0001] The invention relates to a preparation method in the technical field of polymer materials, in particular to a preparation method and application of a covalent organic framework composite material and a composite electrode. Background technique [0002] Covalent Organic Frameworks (COFs) is a class of polymer porous materials with porous structure, which has precise periodicity, large specific surface area and tunable physical and chemical properties. After searching the literature of the prior art, it was found that in 2012 Donglin JIANG et al. published Covalent Organic Framework (covalent organic framework) on pages 6010-6022 of Volume 41 of "Chemical Society Reviews". Compared with traditional linear polymers, covalent organic framework materials are formed by organic units connected by covalent bonds, have stable skeleton structures and permanent nanochannels, and have broad application prospects in the field of energy storage devices such as super...
