Here we present a new strategy for enabling triple shape memory(TSM),in which different shapes may be programmed at one constant fixation temperature during isothermal crystallization of a poly(octylene adipate)elastomer.Unlike traditional TSM programming techniques that utilize separate thermal transitions to encode each distinct shape,here we show that multiple shapes may be encoded independently at different time stages of the same isothermal crystallization process,and then recovered sequentially at different temperatures upon heating.
