▎ 摘　　要

NOVELTY - The preparation method of graphene-based actuation material involves (i) ultrasonically processing the oxidized graphite to obtain an oxidized graphene dispersion liquid, (ii) adding hydrophilic molecules to oxidized graphene dispersion liquid, adjusting the pH to 7.5-9.5, stirring to obtain graft-modified graphene oxide, (iii) washing the graphene oxide, concentrating into 0.001-100 mg/ml solution or slurry, mixing with aqueous inert material, drying to obtain an actuating unit, and (iv) graphically processing the actuating unit. USE - Preparation of graphene-based actuation material used as stomatal microswitch in intelligent garment (claimed). ADVANTAGE - The method enables the preparation of graphene-based actuation material suitable for self-management of body surface temperature and humidity.
