▎ 摘　　要

NOVELTY - Preparing photoelectrically driven cellulose-based flexible phase change material, comprises uniformly mixing stabilizer, water, and conductive material to obtain a continuous phase, dropping a dispersed phase into the continuous phase to obtain an oil-in-water high internal phase emulsion. The dispersed phase is an organic phase change material. A crosslinking agent and a catalyst are added to the oil-in-water high internal phase emulsion under heating and polymerizing to obtain the photoelectrically driven cellulose-based flexible phase change material. USE - Method for preparing a photoelectrically driven cellulose-based flexible phase change material. ADVANTAGE - The method prepares the photoelectrically driven cellulose-based flexible phase change material in a simple and cost-effective manner with good light or electric drive heat storage, high photothermal conversion efficiency of 90%, and good flexibility at room temperature. The photoelectrically driven cellulose-based flexible phase change material is hydrophobic and can be bent and folded. DESCRIPTION OF DRAWING(S) - The drawing shows a thermal infrared image of the photoelectrically driven cellulose-based flexible phase change material.
