Problems solved by technology

It can be known from the above-mentioned prior art that the black phosphorene quantum dots are attached to graphite oxide nanosheets by using solvothermal reaction, freeze-drying, and electrodeposition technologies, so that graphene oxide can be reduced and three-dimensionally shaped to prepare black phosphorene with a special structure. Phosphorene / graphene composite materials improve the sensitivity of composite materials to toxic and harmful substances and microelectronic sensing, but the application of black phosphorene / graphene composite materials in biomedical materials is rare at present

Abstract

The invention provides a black phosphorene modified and fibroin filled porous composite gel material and a preparation method thereof. The preparation method concretely comprises the following steps of adding a black phosphorene solution in a fibroin solution, and performing stirring to obtain a black phosphorene modified fibroin solution; putting the black phosphorene modified fibroin solution ina polytetrafluoroethylene die, performing drying to form a film, then adding the film in a formic acid aqueous solution, and performing uniform stirring to obtain a modified black phosphorene modified fibroin solution; and inserting a positive electrode into a porous material, putting the porous material in the modified black phosphorene modified fibroin solution, inserting a negative electrode,introducing constant voltage, embedding a black phosphorene modified fibroin filling material into the porous material through a mode of electro-gel after electro-gel treatment, and taking out the black phosphorene modified fibroin filling material to obtain the black phosphorene modified and fibroin filled porous composite gel material. As for the prepared fibroin composite, by combining a porousstructure with a gel technology, the wettability and the biocompatibility are almost unchanged, and the mechanical performance is remarkably strengthened.

Description

technical field [0001] The invention belongs to the technical field of silk materials, and in particular relates to a porous composite gel material filled with black phosphorene modified by silk protein and a preparation method thereof. Background technique [0002] Black scale is a black metallic crystal of phosphorus, which has a layered structure similar to graphite. The phosphorus atoms in each layer are also arranged in a hexagonal arrangement. The phosphorus atoms are combined by covalent bonds to form a single-layer structure. There are two different bonds. Length and bond angle, the monolayer is wrinkled in the direction of the armchair, and the monolayers are combined by van der Waals force. Due to the unique geometric structure of black phosphorene, black phosphorene has stable performance in the allotrope of phosphorus. It not only has the most stable chemical properties, but also has good thermal stability, and has good electronic and energy band characteristics,...
