Abstract: In this paper, with the adjusting of D230 and PTMEG, pouring to form different samples and test the shape recovering ratio, the shape recovering time, and the tensile elongation, we study the effect of changes of them to the EP coating’s ability of shape memory and toughness. In this way, we get the best recipe. The result indicates that when the degree of epoxy resin is 70%, the recovery rate and the recovery time is the best. On the base of this, we forming the EP coating and study the electrochemical performance of it. After heating for 30 minutes at 120℃ , the size of the scratch on the coating gets smaller and the corrosion potential rises, indicating the good self-healing capability of the material.
