Can photothermal ice-phobic surfaces be used for anti-icing/deicing?
One promising strategy is to utilize the photothermal effect that harvests ubiquitous solar energy and generates heat for anti-icing/deicing procedure. Owing to their environmentally friendly advantage, the photothermal icephobic surfaces have drawn growing attention in the research community.
Is photothermal Deicing a candidate material for anti-icing/deicing?
The surface temperature can reach 87.1 °C under 2 sun illumination at room temperature, and the photothermal deicing results also prove that it has the potential to become a new candidate material for anti-icing/deicing, as shown in Fig. 12c.
What is a multi-layer photothermal deicing system?
To solve the problem of heat loss at low temperatures, a multi-layer photothermal deicing system (PCP) composed of a photothermal layer (P), thermal-conductive layer (C) and thermal-protective layer (P) was innovatively constructed, as shown in Fig. 13f.
Are photothermal phase change materials effective against icing & deicing?
Due to the constant latent heat value of the photothermal phase change materials, their anti-icing performance is limited and insufficient to meet the requirements of all-weather anti-icing/deicing applications on outdoor equipment surfaces under harsh and complex environmental conditions.
Can photothermal and electrothermal methods be used in anti-icing/deicing?
