  • Ferroelectric polymer electrocaloric material and preparation method thereof
    Patent number: 10625473
    Abstract: A ferroelectric polymer electrocaloric nanowire array and a preparation method thereof, in which the ferroelectric polymer electrocaloric material is formed by a polyvinylidene fluoride (PVDF)-based ferroelectric polymer electrocaloric nanowire array embedded in a porous anodic aluminum oxide (AAO) template. The PVDF-based ferroelectric polymer electrocaloric material is controlled to form a nanowire array embedded in the porous AAO template, and through adopting of a solution infiltration method to prepare the ferroelectric polymer electrocaloric nanowire array in the porous AAO template and improvement of the key morphology, structure, internal microscopic connection construction of the ferroelectric polymer, problems, such as low electrocaloric strength of the ferroelectric polymer, difficult heat conduction in the electrocaloric material and low refrigerating power density of the electrocaloric device in the prior art, can be effectively solved.
