Dynamic capture enabled by sequential phase-switching adhesion.

ABSTRACT: Controllable adhesive interfaces offer unique opportunities for dynamic object capture, especially for aerospace engineering. However, existing approaches often lack the capability to efficiently dissipate impact energy and rapidly protect the adhesive interface during rebound and typically rely on complex mechanical and control systems to fulfill multiple functions. Here, we present a sequential phase-switching adhesion strategy using shape memory polymers (SMPs) to facilitate full-cycle capture operations. The engineered SMP-frame adhesive structure captures targets with normalized kinetic energies exceeding 3800 joules per square meter, empowered by the intrinsic viscoelasticity of the material to provide both strong energy dissipation and rapid adhesive interface strengthening.
