Optimization of the Preparation Condition of WO3 Electrochromic Film by BP Nerve Network

摘要

The preparation of WO3 electrochromic film by sol-gel process was introduced, and the orthogonal experiment was designed. The optimized condition that the dosage of tungsten powder, hydrogen peroxide and ethanol were 4g, 20ml and 10ml separately was achieved. Under the condition, the reaction time of the electrochromic film is 6s. And BP nerve network is used to analyze the influence factors of the reaction time such as dosage of tungsten powder, hydrogen peroxide and absolute ethanol.
