NOVELTY - Odor releasing film device comprises two conductive glass sheets and a gel odor material between the two conductive glass sheets, where the gel odor material comprises polymers, conductive components and flavor, and the polymer comprises polyacrylamide, poly-N-isopropylacrylamide, chitosan, polyacrylic acid, polyvinyl alcohol, triethylene glycol polymethacrylate, polydimethylaminoethyl methacrylate and/or its copolymer composition, and the conductive component comprises poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS), silver nanowires, polypyrrole, polythiophene, and/or graphene. USE - The odor releasing film device is useful as a smell control device in an olfactory item i.e. human body, for releasing smell in a special scene. ADVANTAGE - The device has simple preparation method, adjustable volume size, high application value and excellent application prospect in the actual olfactory item, and is capable of controlling the release rate of the smell of multiple gears, and realizing controllable release of smell material.
