“…by utilizing ample environmental light and environmental friendliness without harmful chemicals (19)(20)(21)(22)(23). Recently, it has been shown that plasmonic (21,24,25), magnetic particles (20,26), and carbon nanomaterials (26,27) can be utilized in photothermal surfaces to generate heat from photo/solar energy and melt accumulated ice. However, there are limitations and remaining challenges.…”

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 demonstrate a low-cost, high-efficiency superhydrophobic photothermal surface, uniquely based on inexpensive commonly seen candle soot. It consists of three components: candle soot, silica shell, and polydimethylsiloxane (PDMS) brushes. The candle soot provides hierarchical nano/microstructures and photothermal ability, the silica shell strengthens the hierarchical candle soot, and the grafted low-surface-energy PDMS brushes endow the surface with superhydrophobicity. Upon illumination under 1 sun, the surface temperature can increase by 53 °C, so that no ice can form at an environmental temperature as low as −50 °C and it can also rapidly melt the accumulated frost and ice in 300 s. The superhydrophobicity enables the melted water to slide away immediately, leaving a clean and dry surface. The surface can also self-clean, which further enhances its effectiveness by removing dust and other contaminants which absorb and scatter sunlight. In addition, after oxygen plasma treatment, the surface can restore superhydrophobicity with sunlight illumination. The presented icephobic surface shows great potential and broad impacts owing to its inexpensive component materials, simplicity, ecofriendliness, and high energy efficiency.

“…Nevertheless, the adhesion force between the frozen water droplet and modified silicone rubber surface in the parallel and vertical directions is reduced to 1.1 and 2.3 N, respectively. The frozen droplet has a smaller liquid–solid area on the hierarchical nanostructured surface, thereby reducing the ice adhesion force 29 . The above self‐cleaning and anti‐icing properties make the modified surface can effectively reduce the damage caused by surface pollution, ice formation, and other natural factors when applied to power lines, sealing elements, automotive, and aviation.…”

Silicone rubbers with high dynamic superhydrophobic stability have an extensive application prospect. Applying direct laser etching technology, a fast and efficient method is proposed for the preparation of silicone rubber surfaces with hierarchical nanospheres and robust dynamic superhydrophobicity. A 4 μl water droplet on the laser modified silicone rubber surface exhibits a contact angle (CA) of 154 ± 3 and a roll-off angle (RA) of 5 ± 1 , there is a 65.6% increase in CA compared with the pristine silicon rubber. Moreover, the modified surface can stabilize its superhydrophobic state under a dynamic pressure of 1960.2 Pa. Interestingly, no significant change in the contacting time for the droplets with different impacting speed is found, which means that the stabilized contact time and robust dynamic superhydrophobicity are induced on the modified silicone rubber surface. The self-cleaning and antiicing properties on the modified surface can effectively reduce the damage caused by surface pollution, ice formation, and other natural factors when applied to power lines, sealing elements, and automotive.

“…[ 139 ] Jiang et al fabricated a superhydrophobic SiC/CNT coating by spray coating, in which CNTs provided both a superhydrophobic structure and photothermal layer. [ 140 ] The surface temperature could increase rapidly under near infrared irradiation, and the generated heat was transferred fast to the surroundings due to the good thermal conductivity of CNTs. The deicing performance could be further enhanced by combining the photothermal with electrothermal effects using a conductive CNT‐based coating.…”

Solar energy is an abundant clean and renewable energy source that has found wide uses in many energy‐intensive applications. It is normally transformed into other forms for certain applications, and light‐to‐heat conversion is one of the most common and efficient ways to utilize solar power. Previous reviews mostly focus on the solar‐driven evaporation for desalination, but few mention other applications in which the photothermal materials play a vital role. Herein, a Review regarding the sustainable uses of photothermal devices beyond desalination is presented. The recent developments of photothermal materials and progress on their applications in wastewater treatment, oil‐spill cleanup, moisture capture, energy harvesting during evaporation, sterilization, deicing, etc. are summarized. Herein, the working principles as well as property requirements in these applications are discussed and also the challenges with opportunities in future research are presented.
