摘要： The present disclosure provides a precursor solution of a semiconductor electrothermal film, which comprises component A, component B, and component C. The component A comprises the following components by weight: 2-10 parts of tin tetrachloride pentahydrate, 3-6 parts of stannous chloride and 0.3-1 part of glycerol, also comprises a pH regulator, the pH of the component A is 4.7-6.2; the component B comprises the following components by weight: 5-10 parts of conductivity regulator, the conductivity regulator is selected from a group consisting of antimony trichloride dihydrate, bismuth trioxide, aluminum oxide and thallium dioxide, 0.6-1 part chlorinated aluminum and a mixture thereof, also comprises a pH regulator, the pH of the component B is 4.7-5.0; the component C comprises the following components by weight: 0.5-0.7 parts of tin oxide, 0.8-1.5 parts of bismuth oxide and 15-25 parts of ethanol; also comprises 15-30 parts of distilled water. A preparation method of electrothermal film and electrothermal structure is further provided. The obtained semiconductor electrothermal film has good nature of resistance to sudden temperature changes, good temperature stability, attenuation resistance, fast heating speed, and high temperature resistance.
