▎ 摘　　要

NOVELTY - Superhydrophobic material comprises comprises reduced graphene oxide/polyurethane sponge composite material. USE - Superhydrophobic material used in a human-computer interaction, a robot, an e-skin, or a wearable device, and also in sensor (all claimed). ADVANTAGE - The superhydrophobic material has superhydrophobicity, used in equipment with high requirements for waterproofing, and has high market value. The preparation process is simple, easy to operate, and the raw materials selected are cost-effective, and suitable for large-scale production. The sensor has superhydrophobicity, and the sensitivity is reach up to 3.8, and has accurate detection of small pressure and fast response, and has a high market value. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a superhydrophobic material, which involves mixing the graphene oxide aggregate with polyurethane sponge to prepare composite sponge freezing the composite sponge, and then reacting with a reducing agent to prepare the super-hydrophobic material.
