NOVELTY - Electrothermal coating slurry comprises 3-6 pts. wt. conductive substance, and 2.7-5.5 pts. wt. silane; the conductive substance is metal-doped oxide; the silane is at least one of alkoxysilane and alkenoxysilane. USE - The coating slurry is useful for electrothermal coatings on glass and/or rearview mirror of energy automobile. ADVANTAGE - The coating slurry: formed coating has long life, and will not produces toxic and harmful gases at high temperatures. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing the electrothermal coating slurry comprising adding acidic substance to the dispersion liquid of the conductive substance, adjusting the pH to 4-5, and obtaining a mixture-I; mixing mixture-I and the silane solution and reacting to obtain the electrothermal coating slurry. (2) Electrothermal coating comprising coating the coating slurry on the surface of the electric heating device and drying to obtain the electric heating coating.
