Abstract

The invention provides a polythiophene nanometer conductive composite material and a preparation method of the polythiophene nanometer conductive composite material based on the advantages of attapulgite of special crystal structure, physico-chemical property and low price, solving the shortcoming in the prior art that the polythiophene-inorganic nanometer composite material is high in cost. The polythiophene nanometer conductive composite material is an iodine-doped porous rod shaped silica / polythiophene amorphous conductive composite material. The preparation method of the polythiophene nanometer conductive composite material comprises the following steps in sequence: dissolving a thiophene monomer into an organic solvent I; adding purified nano attapulgite and an oxidant to an organic solvent II; dropping the mixture to the thiophene solution in an one-by-one way so as to prepare the thiophene / polythiophene nano composite material; and placing the prepared thiophene / polythiophene nano composite material into the iodine vapor to prepare into the porous rod shaped silica / polythiophene amorphous conductive composite material.

Description

technical field [0001] The invention belongs to the technical field of preparation of nano-composite materials, in particular to a kind of attapulgite / polythiophene nanocomposite material prepared by chemically oxidizing and polymerizing thiophene on the surface of attapulgite with attapulgite as a nucleus, and then prepared by iodine vapor doping Porous rod-shaped silica / polythiophene nanoconductive composites. Background technique [0002] As an important structural conductive polymer material, polythiophene has attracted much attention due to its advantages of easy polymerization, good photoelectricity, environmental stability and easy regulation of molecular chain structure, especially the composite of polythiophene and inorganic nanomaterials. Polythiophene and nanomaterials have attracted more and more interest because of their special properties. In recent years, composite materials of metals, metal oxides, carbon materials, polythiophene and its derivatives have bee...
