23 Jul Preparation method of shell-like structure cellulose nanofiber/black phosphorene composite film
Abstract
The invention discloses a preparation method of a shell-like structure cellulose nanofiber/black phosphorene composite film. The method comprises the following steps: obtaining stably existing cellulose nanofiber/black phosphorene dispersion by virtue of hydrogen bond interaction, and forming the layered cellulose nanofiber/black phosphorene composite film in a self-assembly manner. According to the preparation method disclosed by the invention, the cellulose nanofiber serves as a construction module of a black phosphorene nano-composite film, self-assembly is performed by adopting a vacuum suction filtration method, and the shell-like structure layered composite film having excellent mechanical property and fireproof performance. The cellulose nanofiber/black phosphorene composite film prepared by the invention has an ordered ‘brick-mud’ layered structure, is excellent in mechanical property, additionally has excellent biocompatibility, and can be applied to the fields of tissue engineering, biological medicines and the like.
