▎ 摘　　要

NOVELTY - Preparing conductive filter paper with super-hydrophobic performance comprises (i) uniformly coating the graphene slurry on the filter paper, and drying completely, (ii) soaking the obtained filter paper in the manganese(II) sulfate solution for 3-8 minutes, (iii) taking out the obtained in step (ii), removing the residual liquid on the surface of the filter paper, then placing into sodium hydroxide solution, and soaking for 2-10 seconds, (iv) removing the obtained by step (iii), removing surface residual liquid, introducing into the low surface energy agent solution, and soaking. USE - Preparation method of conductive filter paper with super-hydrophobic performance for preparation of the waterproof wearable flexible device. Uses include e.g. wearable electronic sensors, electronic skin, corrosion-resistant circuits, wearable rechargeable batteries, super capacitors, health monitoring systems, electronic bracelets, flexible displays, and sensors. ADVANTAGE - The conductive filter paper is light and thin, foldable and satisfies the market demand. The preparation method is simple, convenient, low cost, small influence on the environment, has mild reaction conditions, a low requirement to the reaction device, and can be produced on a large scale. The prepared super-hydrophobic conductive paper has good flexibility and conductivity, strong waterproof ability, suitable for electronic device requirements of various shapes. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a conductive filter paper with super-hydrophobic performance. DESCRIPTION OF DRAWING(S) - The drawing shows a surface microstructure of super-hydrophobic conductive filter paper.
