Abstract

The application provides a ternary composite nanofiber for marine metal corrosion prevention and electromagnetic wave absorption, and a preparation method and application thereof. The preparation method of the ternary composite nanofiber comprises the following steps: (1) preparation of a precursor solution: dispersing copper salt and a cobalt compound in a first solvent, stirring until fully dissolved, adding a polymer, and uniformly mixing to obtain the precursor solution; (2) preparation of a nanofiber membrane: electrospinning the precursor solution to obtain a nanofiber membrane loaded with copper and cobalt metal ions; (3) carbonization: drying the nanofiber membrane, and performing high-temperature treatment after drying, so that the ternary composite nanofiber for marine metal corrosion prevention and electromagnetic wave absorption is obtained. The preparation method of the ternary composite nanofiber is simple, low in cost, and has great application prospect in electromagnetic wave shielding in marine and other corrosive environments.
