Flower-shaped graphene, melt-blown cloth, preparation methods of flower-shaped graphene and melt-blown cloth, and mask

The invention belongs to the field of graphene preparation and application, and particularly relates to flower-like graphene based on electrochemical treatment, a preparation method of the flower-likegraphene and application of the flower-like graphene in melt-blown products. The flower-like graphene is composed of a plurality of mutually independent graphene aggregates, each graphene aggregate is formed by curling a single-layer or multi-layer ultrathin two-dimensional nano material, and the size of each single graphene aggregate ranges from 50 nm to 200 nm. The flower-like graphene materialcan effectively improve the air permeability of the filtering performance of the composite melt-blown cloth, and endows the composite melt-blown cloth with excellent antibacterial performance and mechanical properties. Melt-blown cloth prepared from the flower-like graphene has excellent properties of lipophilicity, hydrophobicity, bacteria resistance, bacteriostasis, strong adsorption capacity and the like, and a mask pr
