Ice can lead to inconvenience and disasters in human activities, making it a widely concern for researchers to find solutions to prevent icing. Hydrophobic materials have been developed for passive anti-icing with a long time, but without active deicing effect. Recently, researchers have explored hydrophobic photothermal materials with passive anti-icing and active deicing ability, which are limited on cloudy days and the night. Consequently, developing materials with anti-icing/icephobic and deicing capabilities for all-weather use has emerged as an innovative strategy. This paper develops hydrophobic PDMS/Cu-Ni@PET with photo/electric thermal properties to support all-weather anti-icing/icephobic and deicing, which is synthesized using copper-nickel and hydrophobic polydimethylsiloxane (PDMS). The PDMS/Cu-Ni@PET exhibits an outstanding anti-icing performance with a delayed icing time of 1224 s at -10 °C, and achieves a surface equilibrium temperature of 68.9 °C under 1 sunlight intensity, enabling the melting of surface ice particles within 614 ± 118 s. When a voltage is applied to both sides of the fabric, the equilibrium temperature can be reached within 60 s, and attained 158 °C at 6 V, enabling the melting of surface ice within 97 s. It provides a novel approach for developing photo/electric thermal superhydrophobic coatings that can maintain all-weather deicing performance.

Superhydrophobic material has great potential applications in the field of anti-icing due to its special wettability . However, the poor wear resistance of the material has restricted its practical applications. Based on this, a simple two-step spray method was used to prepare a self-healing and robust superhydrophobic coating with excellent photothermal/electrothermal effect for anti-icing using epoxy modified ethylene octene copolymer (POEG) resin as the substrate layer and the fluorinated carbon black as the top coating. Results showed that the obtained composite coating showed multi-level rough structure and possessed excellent superhydrophobicity toward water droplets with different pH. Meanwhile, the composite coating could resist abrasion and kept superhydropbobicity even 250 cycles abrasion test with a water contact angle higher than 150 o . When the surface was subjected to the intense abrasion, the rough structure and the superhydrophobic property of the surface were destroyed. However, it could be restored by the abrasion of the rougher surface. In addition, the scratches on the surface could be completely repaired by the heat treatment, indicating the good self-healing performance of the composite coating. Due to the existence of the carbon black particles, the superhydrophobic coating had good photothermal/electrothermal effects, which endowed the surface with excellent anti-icing performance of removing the icing under the conditions of electrothermal and light. This paper provides a simple and convenient way to prepare functional self-healing superhydrophobic coating, and a new idea for the preparation of anti-icing coating.

Icing is a natural phenomenon, and it is unavoidable, leading to severe economic issues and endangering life safety, especially icing over the aircraft fuselage. Hence, it is highly desirable to adopt effective method to address it. Wherein, the construction and modification of hydrophobic coating is a promising way. In this study, the aluminum-based photothermal/electrothermal composite hydrophobic coating with excellent performance was fabricated by facile spraying of epoxy resin, graphene, polydimethylsiloxane and gaseous nano-silica over etching Al. This coating displayed excellent hydrophobicity, with a water contact angle of 137.4°, which effectively delayed the freezing time of droplets on the cold platform at −10 °C to 360 s. Notably, the superior electrothermal performance enabled the temperature to reach to ca. 80 °C at the voltage of only 1.8 V, melting the ice particle in 164 s and the ice layer with 3 mm thickness in 360 s under the voltage of 1.5 V. Besides, at 1 sunlight intensity, the photothermal effect realized the surface temperature of ca. 45 °C, and the ice layer with 3 mm thickness was melted within 460 s. The multi-effect deicing coating also exhibited excellent photothermal/electrothermal stability and self-cleaning ability. These findings raise new possibilities for the design and development of metal substrate anti-icing/deicing functional coating material.

Ice accumulation often threatens the safety of human life and property. How to effectively solve the problem of solid surface icing has been the research work of many researchers. However, how to prepare superhydrophobic and anti-icing film with multi-strategy collaborative deicing is still facing great challenges. In this paper, a design strategy of photothermal and electrothermal superhydrophobic nanocomposite film based on polyetherimide (PEI) was proposed. Multi-walled carbon nanotubes (MWCNT) were dispersed in PEI matrix by solution blending method, and a lotus leaf like rectangular micropillar array was constructed on the surface of the film by laser etching technology. Then, the surface was fluorinated to further reduce the surface energy. Finally, a kind of MWCNT/PEI nanocomposite film with passive anti-icing and active deicing with photothermal and electrothermal collaboration was successfully prepared. The freezing time of droplets on MWCNT/PEI nanocomposite film is about 6.7 times longer than that of pure PEI film. This film exhibits excellent superhydrophobicity (CA = 156.6°), while also having excellent photothermal and electrothermal conversion properties. In addition, we also conducted various tests on MWCNT/PEI nanocomposite film to verify its reliability in the actual application environment. The MWCNT/PEI nanocomposite film with the function of anti-icing and photothermal and electrothermal active deicing is expected to solve the problem of solid surface icing in daily life, and also provides a new idea for the development of a new generation of anti-icing/deicing film.

A laser induction process was applied to a previously developed FDM 3D-printed graphene enhanced thermoplastic polyurethane structure. Notably, the orientation of graphene flakes and the integrity of the double-layer structure were preserved during the decomposition of the polymer matrix, resulting in anisotropic electrical conductivity (R TP /R IP of 2.47 × 10 7 ) and thermal conductivity (TC IP /TC TP of 9.1). The laser treatment removed the polymer matrix and generated porous graphene flake micro/nanostructures on the surface led to significant improvement in surface hydrophobicity. Despite the defects introduced by the process, most of the mechanical properties were retained, with over 63.3 % of tensile strength and 72.2 % of elastic modulus preserved. A noticeable increase in the coefficient of friction (COF) of graphene enhanced TPU was observed, which was attributed to the synergistic effects of the low COF of the porous graphene flake layer and the high COF of the polymer residue. The excellent heat retention of the structure, ensured by the low thermal conductivity in the TP direction and the enhanced photothermal effect, was systematically evaluated. The photothermal de-icing performance demonstrated a nearly 20 % reduction in ice melting time and electrothermal de-icing performance proved an effective and safe operation voltage of 20 V, confirming its efficacy in practical applications.

Recently, the crude oil spill has brought inevitable harm to the global ecological environment. Due to the high-viscosity crude oil, it is wise to take advantage of the photothermal/electrothermal effects of the membrane to separate the crude oil from the water. However, the functional separation membrane always suffers from low photothermal/electrothermal effects and poor stability. Herein, the vinyl polyvinylidene fluoride/mercapto carbon nanotubes@vinyl-terminated polydimethylsiloxane (PVDF-a/CNT-s@PDMS) membrane with fast photothermal/electrothermal effects and organic absorption property was successfully prepared by electrospinning and multi-layer loading method. The prepared PVDF-a/CNT-s@PDMS membrane resisted a variety of liquids and had stable superhydrophobicity (WCA = 156°). Furthermore, the membrane maintained superhydrophobicity even suffer from water and milk under the applied voltage condition. After 100 wear resistance tests, the membrane maintained stable superhydrophobicity and the separation rate remained unchanged. The surface temperature of the membrane rapidly approached to the maximum temperature in 30 s, showing a rapid photothermal/electrothermal effects, and the average separation rate of crude oil was 1185 kg m −2 h −1 ·bar −1 . Meanwhile, the membrane exhibited outstanding efficiency for separate immiscible oil-water mixtures. Importantly, the incorporation of the sulfhydryl group enhanced the special ability of the composite membrane to adsorb organic dyes from oil phase. Therefore, the PVDF-a/CNT-s@PDMS membrane has a wide range of potential application in the domain of oil-water separation.

This work presents a multifunctional composite film with integrated photothermal and electrothermal conversion, electromagnetic interference (EMI) shielding, and active de-icing capabilities, fabricated via electrospinning combined with layer-by-layer (LbL) self-assembly. Polydopamine (PDA)-modified thermoplastic polyurethane nanofiber membranes (PDA@TPU) served as the substrate. Synergistic interaction with sodium alginate (SA) enabled the layer-by-layer self-assembly of molybdenum disulfide (MoS₂) and carbon nanotubes (CNTs) onto the substrate surface. Subsequent Ca 2+ drop-addition reaction cross-linking ultimately formed a robust and stable coating. The PDA and SA layers significantly enhance interfacial adhesion between the conductive fillers (MoS₂/CNTs) and the polymer matrix, ensuring mechanical durability and efficient thermal conversion. The resulting five-layer film exhibits excellent performance: a photothermal temperature rise of 69.2 °C under 1 sun irradiation (100 mW/cm 2 ), electrothermal heating exceeding 80 °C at 7 V, and an EMI shielding effectiveness of 33.8 dB in the X-band. Notably, this film exhibits outstanding durability, with its electrical conductivity remaining virtually unchanged after repeated washing. Under dual photothermal and electrothermal stimulation (1 sun +7 V), the film can completely melt surface ice within 60 s, effectively preventing electromagnetic shielding efficiency degradation caused by ice accumulation. The layer-by-layer self-assembly technique based on PDA and SA systems offers a novel strategy for fabricating multifunctional composite films with outstanding comprehensive properties, demonstrating broad application prospects.
