Abstract
Composite materials and devices including composite materials are disclosed. Exemplary composite materials include a porous material and ferroelectric nematic liquid crystal within pores of the porous material. The composite materials can be used in a variety of applications, such as capacitors, information storage and processing, actuators, sensors, electro-caloric devices, energy storage and/or conversion devices utilizing piezoelectric effects. The porous material can be a solid, a polymer, glassy, crystalline, amorphous, foam, an aerogel or ceramic.
