A flexible skin material with switchable wettability for trans-medium vehicles

Trans-medium vehicles can achieve both load reduction and trajectory stabilization through the adaptive adjustment of head configurations and surface wettabilities, necessitating a flexible skin material with switchable wettability. However, conventional deformable materials often exhibit insufficient load-bearing capacity under impact loads, and their deformation can cause the failure or delamination of surface coatings, leading to undesirable changes in wettability. In this paper, shape memory polymer (SMP) is utilized as the substrate of the flexible skin material, and is reinforced with S-shaped shape memory alloy (SMA) wires to overcome inherent limitations in strength and stiffness. A smart, responsive…
