研究目的
To prepare Ni(OH)2/TiO2 nanorod composite porous film with a novel structure and remarkable electrochromic behavior, and compare its performance with pure Ni(OH)2 film.
研究成果
The Ni(OH)2/TiO2 nanorod composite porous film exhibits excellent EC properties and improved cyclic durability compared to pure Ni(OH)2 film, with potential applications in near infrared light area due to its high transmittance contrast.
研究不足
The degradation of transmittance contrast with cycle number and the structural damage of Ni(OH)2/TiO2 film after extensive cycling.
