▎ 摘　　要

NOVELTY - The device has a first copper-reduced graphene oxide core-shell nanowires film layer (200) that is resided on top of a first layer (500) of transparent substrate (100). A layer of polymeric matrix contains suspended particles (310) on the top of the first layer of copper-reduced graphene oxide core-shell nanowires film. A second copper-reduced graphene oxide core-shell nanowires film layer (400) is resided on the layer of polymeric matrix. A second layer of transparent substrate is arranged on the layer of second layer of copper-reduced graphene oxide core-shell nanowires film. USE - Light transmission controlling device. ADVANTAGE - The device improves flexibility, stability and cost in addition to optical transmittance and electrical conductivity. The device simples processing and for physical flexibility of a final device. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a light controlling device.
