Abstract

The invention relates to a poly 3-carboxylic thiophene / thiophene intercalation hydrotalcite composite material and preparation technology thereof, and belongs to the technical field of organic-inorganic composite materials. The chemical formula of the material is [(M2+)1-x(M3+)x(OH)2]x+(PTHC / TH)n-x / n*mH2O, wherein x=0.25-0.33, n=5-35, m=2-4, m serves as the quantity of interlamination crystal water molecules, and the PTHC / TH is poly 3-carboxylic thiophene / thiophene. The preparation technology includes the steps: firstly, preparing hydrotalcite precursor; secondly, intercalating 3-carboxylic thiophene into the hydrotalcite; finally, polymerizing the 3-carboxylic thiophene and the thiophene in situ between hydrotalcite layers. The composite material is high in mechanical strength, resistant to high temperature, corrosive gas and acid alkaline, and has excellent application prospects in the field of capacitors, energy sources, novel batteries and the like.

Description

technical field [0001] The invention relates to a poly-3-carboxythiophene / thiophene intercalated hydrotalcite composite material and a preparation process thereof, belonging to the technical field of organic-inorganic composite materials. Background technique [0002] Conductive polymers are a class of polymers containing conjugated structures, and their electrical conductivity can reach the level of semiconductors or even metals, so they have good application prospects in capacitors, energy sources, metal anticorrosion, and biosensors. Polythiophene and its derivatives are an important class of organic conjugated polymer functional materials, and because of their good stability, processability and conductivity, they can be used as conductive materials, light-emitting diode materials, and electromagnetic shielding materials. , display materials, microwave absorbing materials and new memory materials. After years of development, polythiophene has played an increasingly impor...
