Intrinsic ferroelectric elastomers with ultrahigh Curie temperature and fast polarization switching.

ABSTRACT: Ferroelectric materials are well-suited for advanced wearable electronics, where elasticity and user comfort are paramount. Nevertheless, current ferroelectric elastomers, primarily based on polyvinylidene fluoride (PVDF) copolymers, suffer from low Curie temperature, poor stability under extreme conditions, and sluggish polarization switching, limiting their applicability in high-temperature environments and compromising the sensitivity of devices. To overcome these challenges, we leverage PVDF homopolymers to develop a ferroelectric elastomer with higher Curie transition temperature. Through strategic thermal crosslinking with polyethylene glycol diamine and a melt-memory effect, we have developed intrinsically ferroelectric elastomers that combine thermal stability with fast polarizatio
