FIG.1
Schematic illustration of the underline mechanism in a chemoresponsive SMP. (a) Original configuration in which the elastic and transition segments are tangled together (transition segment is shown as a straight line for better visualization); (b) stretching at high temperature (transition segment becomes soft and can be easily deformed, while the elastic segment is elasticly deformed accordingly); (c) temporary shape at low temperature (transition segment becomes hard at low temperature and thus the recovery of the elastic segment is prevented); (d) shape recovery upon exposure of a solvent which causes the softening of transition segment (the elastic energy in the predeformed elastic segment is release).
