| Popis: | With the development of materials, intelligent materials have the functions of sensing, controlling and driving objects, self-adaptive repair and so on, so they have been widely used. Silk fibroin fiber is a kind of natural protein, which is formed by silk degumming, insoluble in water, and can be decomposed gradually in alkaline solution without irritation and side effects, so it has a good prospect of biological application. The silk fibroin film was mixed with graphene composites, and the intelligent materials for functional response were prepared by means of the excellent optical and thermal properties of graphene. The biaxially oriented polypropylene film (BOPP) / silk fibroin bilayer composite film was prepared by the simple composite method, which showed good thermal response bending deformation properties. The graphene solution was dripped on one side of the fibroin film by a dripping method. After low-temperature drying, the final BOPP/SF/RGO/PEDOT:PSS composite film was prepared by adding a layer of poly (3meme 4-ethylenedioxythiophene / polystyrene sulfonate) (PEDOT:PSS). The flexible film driver was prepared, which can respond to multiple stimuli under light, heat and humidity. |
