    摘要： A downhole element to isolate or complete a wellbore includes a shape memory material including polyphenylene sulfide. The polyphenylene sulfide is the cure product of being cured at a temperature of about 200° C. to about 400° C., for a total time of less than or equal to 200 hours. The shape memory material is thermally activated between an actuated and unactuated shape, and the polyphenylene sulfide in the shape memory material is a closed cell foam, open cell foam, or solid.
