Slight-Crosslinking: Opening a New Journey for the Intrinsic Elastification of Ferroelectric Polymers

Elastic electronic materials are essential components in the next generation of wearable devices and soft robots. However, the development of elastic ferroelectric materials has lagged behind that of conductive and semiconductive materials. The successful realization of intrinsically elastic ferroelectrics through slight-crosslinking has opened a new path for making ferroelectric materials elastic. Given the critical need for materials that combine excellent elasticity with robust ferroelectric properties in the field of elastic electronics, we explore various crosslinking techniques and their performance characteristics. We believe that this cutting-edge research direction holds substantial value for both fundamental studies and practical applications.
