The invention provides a multifunctional core-shell self-repairing electrospinning material and a synthesis method and application thereof. The shell solution synthesized by this method is composed of shell polymer shell material, shell material solvent, and copper source according to the mass ratio of 0.5−1.5:2−10:0.1−2; The mass ratio is 1:5−10. Precursor nanofibers are obtained by coaxial electrospinning, and gas-phase reduction is performed to obtain multifunctional core-shell self-healing electrospinning materials. The multifunctional core-shell nanofibers were loaded into the resin to obtain a photothermal responsive self-healing coating. The invention can effectively improve the loading rate, loading stability and uniformity of nanometer cuprous oxide on the surface of polyvinyl butyral nanofibers. The invention can improve the mechanical properties of the composite coating. The invention uses Q235 steel as the research base, realizes the combination of intrinsic self-repair and extrinsic self-repair, has excellent corrosion resistance, can effectively improve the corrosion resistance of Q235 steel in a corrosive environment, and has excellent performance on base materials. Protection performance. Through the experimental exploration of key material parts, a process route with the best performance was obtained. |
