Self-encapsulation liquid metal materials for flexible and stretchable electrical conductors

Abstract

A one-step strategy for fabricating flexible conductors <i>via</i> phase separation is proposed, wherein, the liquid metal was implanted into polydimethylsiloxane, whose viscosity was changed using hexane. Such self-encapsulating composite exhibited good electronic and mechanical stability under mechanical cycles with no significant leaking of droplets during the testing process.
