▎ 摘　　要

NOVELTY - The electrochromic device (200) comprises an electrode (202,204) including graphene and a ferroelectric material, and an active layer (203). The electrode comprises two electrodes, each of the two electrodes includes graphene and the ferroelectric material. The electrode comprises the ferroelectric material layer (207,207b) located between layers (206a,206b) of graphene. The active layer comprises a liquid crystal material. The active layer comprises the liquid crystal material dispersed in a polymer. USE - Electrochromic device for use as built or retrofitted electrochromic panels for windows in residential or commercial buildings. Uses include but are not limited to built or retrofitted electrochromic panels for windshields, windows and sunroofs for automobiles, flexible black-and-white or color displays for use as electronic paper either standalone or in electronic readers, adjustable diffusers for residential and commercial lighting installations, adjustable diffusers for camera flashes, heat reduction windows, privacy screens, flexible electrochromic textiles for curtains, lampshades, furniture and coverings, wearable electrochromic apparel, projection screens, or organic light-emitting displays. ADVANTAGE - The electrochromic device comprises an electrode including graphene and a ferroelectric material, and an active layer, thus the nonreactive and impermeable nature of graphene increases the durability of the electrochromic device through increased resistance to external impurities, and allows the electrochromic devices to remain transparent with no external power source. The electrochromic device exhibits a charging effect, which permits recovery of energy stored in alignment of ferroelectric dipoles within the ferroelectric material, and also allows the electrochromic device to be more energy efficient. DESCRIPTION OF DRAWING(S) - The drawing shows a sectional view of an electrochromic device. Electrochromic device (200) Electrode (202,204) Active layer (203) Graphene layer (206a,206b) Ferroelectric material layer (207,207b)
