MXene@PPy based flexible membrane with hydrophobicity, dual-driven heating, and sensibility for helicopter anti-/deicing and icing monitoring

Ice formation seriously affect helicopter flight performance, and serious ice accumulation will greatly threaten helicopter travel safety. To avoid the complex measures for surface ice protection and achieve integration, in this work, an ice defense membrane that based on polypyrrole (PPy) modified Ti 3 C 2 T x (MXene) and polydimethylsiloxane (PDMS) encapsulation was proposed. The test results show that membrane integrate the hydrophobicity (Contact angle could reach to 140.1°), dual-drive thermal property (Temperature of membrane could arrive at 116℃ and 68.3℃ at 7 V voltage supply and 100 mW/cm 2 near-infrared radiation, respectively), and micro-strain sensibility (0.05 % tiny strain for membrane could be sensed). Membrane with multifunction and high-integration can be effectively used in ice management. Anti-icing, deicing and ice detection tests were carried out to confirm the efficiency in passive anti-icing, active deicing, and ice formation detection. Moreover, an intelligent ice defense system based on the membrane and hardware circuit has been designed. This work puts forward a membrane with multifunctional integration for ice defense, which could powerfully deal with the icing problem for the aviation field in the future.
