Nano yellow tungsten oxide may be used to prepare thermal insulation film, which is characterized by its high thermal insulation performance. And this performance is mainly determined by the special crystal structure and unique photoelectric property of WO3. The yellow tungsten oxide also has special surface wettability so that it has broad potential applications in this field. Surface wettability is one of the most important characteristics for a solid surface, which is decided collaboratively by surface energy and surface roughness.…
