Abstract
A micro-nano structure-based super-hydrophobic fabric and a preparation method therefor are disclosed. A brand-new method of combining carbene polymerization covalent grafting with solid surface self-assembly is used for the first time to prepare a modified fabric having super-hydrophobic and self-cleaning functions, by taking an aliphatic diazo compound and an aromatic diazo compound as monomers for carbene copolymerization to graft a fluorine-containing and phenyl-containing block copolymer having a single-carbon repeating unit onto the surface of a fabric by means of a covalent bond. A carbene polymer is crystallized under the induction of the surface of a fiber to drive self-assembly to construct a hierarchical roughened structure having a micro-nano composite structure on the surface of the fabric, and a secondary structure is a nano-scale mastoid-shaped structure imitating a lotus leaf surface.
