“…In previous studies, electrothermal films based on graphene showed excellent electrothermal performance for different applications. By using a femtosecond LIG film for anti-icing/deicing, the temperature could reach 193.1 °C at a voltage of 4 V. 43 By employing stretchable conductors for electrothermal actuating, the temperature could reach 150 °C at a voltage of 12 V. 29 When using LIG composite adhesive tape with antimicrobial capabilities, the temperature could reach >120 °C at a voltage of 10 V. 46 For the graphene grid structure studied, the line width can be further optimized to ensure the wearable characteristics of the electrothermal device and meet the temperature requirements of the heater.…”

Flexible electrothermal films are crucial for protecting equipment and systems in cold weather, such as ice blockages in natural gas pipelines and icing on aircraft wings. Therefore, a flexible electric heater is one of the essential devices in industrial operations. One of the main challenges is to develop flexible electrothermal films with low operating voltage, high steady-state temperature, and good mechanical stability. In this study, a flexible electrothermal film based on graphene-patterned structures was manufactured by combining the laser induction method and the transfer printing process. The grid structure design provides accurate real-time monitoring for the application of electrothermal films and shows potential in solving problems related to deicing and clearing ice blockages in pipelines. The flexible electrothermal film can reach a high heating temperature of 165 °C at 15 V and exhibits sufficient heating stability. By employing a simple and efficient method to create a flexible, high-performance electrothermal film, we provide a reliable solution for deicing and monitoring applications.

Flexible membrane with good anti‐wettability under giant deformation and fast healing will largely extend its adaptability and life span in anti‐/deicing application. A flexible membrane with significant dynamic water repellency and photo‐/electro‐responsive healing capability is reported, fabricated by combining the covalent grafting of fluorosilane to carbon black (F‐CB) with the optimized ablation difference between thermoplastic polyurethane (TPU) matrix and F‐CB. A rolling angle of below 5° is remained after either being stretching to 1000% strain or 2000 cycles of tensile tests at 400% strain. More importantly, multi‐scale cracks on the membrane can be diagnosed and repaired in real‐time; the healing efficiency reaches above 99% within 90 s even if completely fractured under the effect of both solar irradiation of 0.1 W cm−2 and applied voltage of 20 V; and all‐weather anti‐/deicing has the performance of an icing delay time of 323 s and an ice adhesion strength of <40 kPa, a sharp contrast to the 18 s and 1090 kPa, respectively, for bare metal surface. This work endows anti‐icing membrane with the ability of damage detection and cyclic healing, highly demanded in outdoor anti‐/deicing application that involve inevitable mechanical damages.

Superhydrophobic surfaces have attracted significant attention for their ability to prevent ice formation and facilitate deicing without requiring external energy. However, these surfaces are often vulnerable to damage from external forces, leading to functional failure due to poor mechanical stability, which limits their widespread use. Drawing inspiration from the hierarchical groove of rose petals and the micropapillae of lotus leaves, a simple laser‐based method is proposed to create a superhydrophobic surface with a micro/nano hierarchical crater‐like structure (HCLS). To enhance the surface, boiling water treatment is applied to induce dense nanostructures, resulting in an optimal contact angle (CA) of 162° and a desirable sliding angle (SA) of 2.0°. The initial ice adhesion strength of HCLS is as low as 1.4 kPa and remains below 10 kPa even after 300 cm sandpaper abrasion. Furthermore, the HCLS demonstrates excellent mechanical durability, maintaining its performance under conditions that simulate the continuous impact of water and sand in extreme weather. This approach offers an innovative design concept that has the potential to advance the development of anti‐icing and deicing surfaces for future aircraft.
