The icing phenomenon has caused much inconvenience to people's life. With the continuous progress of technology, it has been found that hydrophobic materials can be used in the anti-icing field, however icing still occurs on hydrophobic surfaces with long-term using in extremely harsh environments. Therefore, materials with anti-icing/icephobic and deicing functionalities have become an innovative strategy. In this paper, photothermal hydrophobic materials with anti-icing/icephobic and photothermal deicing properties are prepared using the photothermal nickel, Chinese ink and polydimethylhydrosiloxane with low surface energy. Due to the synergistic effect of the photothermal nickel nanoparticles and carbon nanoparticles in Chinese ink, the prepared material has a fast temperature rise rate at 1000 W/m 2 , which can reach the equilibrium temperature of 72 °C within 80 s. The freezing time of water droplets can be delayed to 1018 s at −15 °C, which is 11 times longer than that of nickel-plated materials. The ice on the coating melts rapidly and slides off along the inclined surface under the sunlight, proving that the material has a good photothermal deicing performance. Additionally, the coated surface has excellent wear resistance and UV resistance, which can be used outdoors for a long time. This powerful electroless nickel plating fabric, integrated with anti-icing/icephobic and fast deicing functionality with photothermal and drag reduction effect, provides a new approach to solve the icing problem in outdoor clothing.

With increasing environmental pollution, superhydrophobic materials for effectively separating oil/water mixtures especially emulsions have attracted considerable interest. Herein, we propose a facile vacuum-filtration approach to fabricating flexible superhydrophobic polydimethylsiloxane@multiwalled carbon nanotubes (PDMS@MWCNTs) membrane. The fabricated membrane had outstanding superhydrophobicity with a water contact angle of 167° and a water sliding angle of 2.9°, self-cleaning ability, and good resistances to cold, hot, strong acid, alkali, and abrasion. Owing to the connected nanoscale pores constructed by the overlapped MWCNTs, the membrane was successfully applied to separate various water-in-oil emulsions and exhibited excellent reusability. Additionally, taking advantage of electrical conductivity and the electrothermal conversion effect, the PDMS@MWCNTs membrane could also be utilized for quick deicing at a low voltage. Our findings provided a new strategy to fabricate functional superhydrophobic materials for various potential applications.

Superhydrophobic cotton fabrics have a lot of potential for use in practical settings. The majority of superhydrophobic cotton fabrics, however, only serve one purpose and are made from fluoride or silane chemicals. Therefore, it remains a challenge to develop multifunctional superhydrophobic cotton fabrics using environmentally friendly raw materials. In this study, chitosan (CS), amino carbon nanotubes (ACNTs), and octadecylamine (ODA) were used as raw materials to create CS-ACNTs-ODA photothermal superhydrophobic cotton fabrics. The cotton fabric that was created showed a remarkable superhydrophobic property with a water contact angle of 160.3°. The surface temperature of CS-ACNTs-ODA cotton fabric can rise by up to 70 °C when exposed to simulated sunlight, demonstrating the fabric’s remarkable photothermal capabilities. Additionally, the coated cotton fabric is capable of quick deicing. Ice particles (10 μL) melted and began to roll down in 180 s under the light of “1 sun”. The cotton fabric exhibits good durability and adaptability in terms of mechanical qualities and washing tests. Moreover, the CS-ACNTs-ODA cotton fabric displays a separation efficacy of more than 91% when used to treat various oil and water mixtures. We also impregnate the coating on polyurethane sponges, which can quickly absorb and separate oil and water mixtures.

Superhydrophobic materials with special functions such as electrical conductivity, magnetism and self-repairing have attracted considerable attention. Herein, a superhydrophobic conductive polydimethylsiloxane@silver nanowires (PDMS@AgNWs) cotton fabric was fabricated via a simple dipping-thermal curing method. Owing to the combination of rough structure constructed by AgNWs and the covered low-surface-energy PDMS, the as-fabricated cotton fabric exhibited superhydrophobicity with a high water contact angle (WCA) of 156°, and the separation efficiency for oil-water mixture reached 95.6%. Importantly, taking advantage of the excellent conductivity and electrothermal conversion performance, the functional cotton fabric was successfully applied in the fields of quick deicing under low temperature and piezoresistive sensing for human motion. Our findings stand out as a new tool to prepare functional superhydrophobic materials with electrical conductivity and electrothermal effect for various potential applications.
