The present application relates to the technical field of separators, and provides a composite separator, a preparation method therefor, and a use thereof. The composite separator comprises a porous layer. The porous layer comprises an organic polymer resin, inorganic particles, and polymer fibers, the polymer fibers being polymer fibers modified with hydrophilic groups.

In addition, hydrogen bond interactions are formed between the hydrophilic groups modified on the polymer fibers and the inorganic particles. Considering also the strong interactions between the polymer fibers and the organic polymer resin, this arrangement helps to fix the inorganic particles within the organic polymer resin, thereby effectively reducing detachment of inorganic particles from the porous layer. As a result, the separator has good air tightness, which helps to maintain the stability and safety of the separator.
