NOVELTY - Preparing renewable biomass nanofiber involves using diatom as raw material contains diatom, graphene and renewable biomass. The graphene oxide penetrates into cells of diatoms and/or adheres to surfaces of the diatom cells. USE - Method for preparing renewable biomass nanofiber. ADVANTAGE - The method enables to prepare renewable biomass nanofiber which has improved mechanical and functional properties of fibers, and excellent overall performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing regenerated biomass nanofiber using diatom as raw material, which involves: (A) adding graphene solution sterilized with ultraviolet light to the cultured diatoms, continuing to cultivate for 10-20 days, taking out, centrifuging, and then adding water to disperse to obtain a diatom solution of adsorbed graphene; (B) adding diatom solution adsorbing graphene oxide to regenerated biomass solution and mixing uniformly to obtain diatom modified regenerated biomass solution adsorbing graphene; and (C) mixing diatom-modified regenerated biomass solution adsorbed with graphene with an auxiliary agent to form spinning solution to obtain desired product.
