NOVELTY - Method for preparing a self-repairing material involves preparing the self-repairing material using a photo-thermal material and a matrix material and adopting steps such as (1) placing the photo-thermal material in a beaker, adding water and uniformly dispersing the photo-thermal material in water by means of an ultrasonic dispersion method to obtain a photo-thermal material dispersion, (2) placing the matrix material in a beaker, adding water and uniformly dispersing the matrix material in water by an ultrasonic dispersion method to obtain a matrix material dispersion, (3) mixing the photo-thermal material dispersion with the matrix material dispersion and performing ultrasonic dispersion to obtain a mixed solution and (4) performing vacuum suction filtration on the mixed solution. USE - The method is useful for preparing a self-repairing material used for preparing a driving material. ADVANTAGE - The method provides the product that can endow the drive material with a self-repair function, where the water-assisted self-repairing method can quickly repair the damaged drive, which is conducive to the application in actual production and life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing a driving material involving attaching the self-repairable material to a polymer material with thermal expansion effect to obtain the driving material.
