▎ 摘　　要

NOVELTY - Waterproof and moisture-permeable composite fabric preparation involves dissolve fluorinated graphene in N,N-dimethylformamide, pouring into flask under sonication for 4-6 hours to obtain a dispersion. Polyurethane and aziridine isocyanate are added to the dispersion with stirring at room temperature for 3-4 hours to prepare a spinning solution containing fluorinated graphene. The fluorinated graphene-containing spinning solution is passed through an electrostatic spinning device to obtain a waterproof and moisture-permeable composite membrane containing fluorinated graphene. The hot melt adhesive powder is dissolved in N,N-dimethylformamide to prepare an electrostatic spinning solution, where the hot melt adhesive is prepared by electrostatic spinning. USE - Method for preparing waterproof and moisture-permeable composite fabric containing fluorinated graphene used in medical and health, building exterior walls, aerospace and aquatic industries. ADVANTAGE - The method prepares the waterproof and moisture-permeable composite fabric containing fluorinated graphene in a simple, cost-effective and eco-friendly manner with super-hydrophobicity, high efficiency, good air permeability and energy saving. The pore structure has good air permeability, which can effectively block the external bad weather and prevent the penetration of rain and snow, and can also promptly discharge the sweat and moisture generated by the human body due to exercise, and thus regulates human microenvironment to provide good comfort for the human body. DETAILED DESCRIPTION - Waterproof and moisture-permeable composite fabric preparation involves dissolve fluorinated graphene in N,N-dimethylformamide, pouring into flask under sonication for 4-6 hours to obtain a dispersion. Polyurethane and aziridine isocyanate are added to the dispersion with stirring at room temperature for 3-4 hours to prepare a spinning solution containing fluorinated graphene. The fluorinated graphene-containing spinning solution is passed through an electrostatic spinning device to obtain a waterproof and moisture-permeable composite membrane containing fluorinated graphene. The hot melt adhesive powder is dissolved in N,N-dimethylformamide to prepare an electrostatic spinning solution, where the hot melt adhesive is prepared by electrostatic spinning. The base fabric side of the waterproof and moisture-permeable composite film containing fluorinated graphene prepared is hot-pressed with the hot melt adhesive mesh film to obtain the waterproof and moisture-permeable composite fabric containing fluorinated graphene. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic field emission electron micrograph of the waterproof and moisture-permeable composite fabric containing graphene fluoride.
