Abstract

The invention belongs to the technical field of material chemistry, in particular relates to a vanadium dioxide precursor liquid and a method for preparing a thin-film material by using the same. The vanadium dioxide precursor liquid of the invention comprises a soluble vanadium salt, a film forming accelerator and a solvent. The invention further provides a method for preparing a vanadium dioxide thin film by using the vanadium dioxide precursor liquid. The invention overcomes the shortages of the prior preparation technique of liquid-phase vanadium dioxide, reduces the cost of raw materials, and can previously reduce or oxidize the vanadium raw material in the raw materials to quadrivalence so that vanadium element is not necessarily subjected to an oxidation-reduction reaction in the process of thermal treatment. The vanadium dioxide thin film prepared by the invention has uniform phase, good purity and intelligent response to temperature. The vanadium dioxide thin film prepared ona glass substrate has a light transmittance peak value up to 70% at most in a visual light region and an infrared light regulating performance up to 60% at most, and has wide application prospect in the fields of optical functional materials and electric functional materials.

Description

technical field

[0001] The invention belongs to the technical field of material chemistry, and in particular relates to a vanadium dioxide precursor solution and a method for preparing thin film materials. Background technique

[0002] my country is an energy-short country, but the current energy consumption per unit building area in my country is 2 to 3 times that of developed countries, and the total energy consumption of buildings in my country is showing an upward trend year by year. The proportion of my country's building energy consumption in total energy consumption has risen from 10% in the late 1970s to about 30% in 2007. At present, my country is in the stage of rapid industrialization and urbanization. The area of ​​houses built every year is as high as 1.6 billion to 2 billion square meters, which exceeds the sum of the annual built areas of all developed countries, and more than 95% of them are high energy consumption buildings. These buildings will continue to...
