Superhydrophobic photothermal icephobic surfaces based on candle soot

Abstract: Ice accumulation causes various problems in our daily life for human society. The daunting challenges in ice prevention and removal call for novel efficient antiicing strategies. Recently, photothermal materials have gained attention for creating icephobic surfaces owing to their merits of energy conservation and environmental friendliness. However, it is always challenging to get an ideal photothermal material which is cheap, easily fabricating, and highly photothermally efficient. Here, we demonstrat… Show more

“…It was found that the PU/P(NiPAAm‐bis‐AA) could still form an inverse opal photonic structure with show bright structural color, while the candle soot coating not only enhances the vivid color of the structural color but also form a superhydrophobic surface. [ 36–38 ] In addition, benefiting from the Janus wettability and interfacial floatability, the external stimulus responsiveness of the Janus film not only output membrane's directional migration induced by the Marangoni effect on the water surfaces but also induces structural color changes. [ 39 ] Thus, it was demonstrated that the composed Janus membrane could not only report the arrival of variables via directional migration obviously, but also quantitively feedback the stimuli through visually structural color variations.…”

“…The traditional passive anti-icing surfaces mainly included nanostructured superhydrophobic surfaces (SHS) [ 9 , 10 , 11 ] and slippery liquid-infused porous surfaces (SLIPS). It had been proved that those surfaces had anti-icing properties since surface-free energy reduced [ 11 ].…”

“…The traditional passive anti-icing surfaces mainly included nanostructured superhydrophobic surfaces (SHS) [ 9 , 10 , 11 ] and slippery liquid-infused porous surfaces (SLIPS). It had been proved that those surfaces had anti-icing properties since surface-free energy reduced [ 11 ]. According to the Cassie-Baxter model, the air trapped in the nano-texture beneath the droplet contributed to the low ice adhesion of SHS, extremely large water contact angle, and the icing delay [ 10 , 12 ].…”

“…The CS deposited superhydrophobic surface is playing a vital role in various applications 38–40 . Wu et al 40 have developed a photothermal icephobic surface by simple surface modification of soot coated glass substrate. The surface modification was performed by chemical vapor deposition of tetraethoxysilane (TEOS) on the soot coated glass surface followed by immersion in 2% PDMS‐hexane solution.…”
