Abstract

The invention provides a preparation method of inorganic nanometer materials and polythiophene derivant composite materials, comprising the steps: mixing the polythiophene derivant monomer with the inorganic nanometer materials; and under the existence of catalyst, carrying out oxidation polymerizing at the temperature of -5 DEG C to 30 DEG C. By using the method, the polythiophene derivant and the nanometer inorganic materials can be effectively composited, so that the nanometer inorganic materials are dispersed into the molecule intervals of the polythiophene derivant, packed by the molecules, and mutually acted. The ultraviolet visible absorption peak of the composite materials is obviously red shifted, the whole ultraviolet and visible absorption zone is covered by a luminous range, and the light absorption performance is greatly improved. Furthermore, the composite materials overcome the defects of an n-type semiconductor and a p-type semiconductor, thus greatly improving the electrical conductivity in the whole scan voltage range. The composite materials are expected to be practically used in photoelectric devices and solar cells.

Description

technical field [0001] The invention relates to a composite material of an inorganic material and an organic semiconductor material and a preparation method thereof, in particular to a composite material of an inorganic nanometer material and a polythiophene derivative and a preparation method thereof. Background technique [0002] Organic-inorganic composite materials are research hotspots in recent years, and their specific and excellent properties have attracted more and more attention. At present, organic-inorganic composite materials have become one of the most promising and fastest-growing branches in the field of material chemistry. The heterogeneity of the spatial position and the dissimilarity of the properties of each component make this kind of composite materials have distinctive structural characteristics, physical properties and complex functions. It can be applied in many technical fields, optoelectronic materials, solid electrolytes, coating processes, senso...
