US 2025/0026954 A1 · ANIONIC EXPLOSION-PROOF MEMBRANE AND PREPARATION METHOD THEREFOR

Abstract

Provided in the present disclosure are an anionic explosion-proof membrane and a preparation method therefor. A surface of the anionic explosion-proof membrane contains two layers of hardened coatings, wherein the hardened coatings respectively contain anionic agent particles with different concentrations and different particle sizes, and a certain gradient is present in the concentrations of the anionic agent. The anionic agent on the inner layer has a relatively high concentration and a relatively large particle size, and the negative ion agent on the outer layer has a relatively low concentration and a relatively small particle size; therefore, the explosion-proof membrane has an efficient and lasting negative ion release capacity.
