The Shape Memory Mechanism and Properties of Thermosensitive Shape Memory Polymers

The relationship between aggregation structure and shape memory properties of shape memory polymers is investigated(there are three types of aggregation structure: both reversible phase and fixed phase are amorphous;reversible phase is amorphous,fixed phase is crystal;reversible phase is crystal,fixed phase is amorphous).Aggregation structure has different effect on transition temperature,storage modulus,shape fixed/recovery rate,recovery stress and recovery speed.
