Background technology
Self-repair material is a kind of when damage of material or when there is crackle, and self can be carried out under the conditions of without external influence
The intellectual material of reparation.The core of self-repair material is material supply and energy supply.
The fundamental mechanism of common self-healing polymers is to rely on capsule or train of thought release or conveying when crackle occurs
Liquid material solidification, complete to fill the material of crackle space of planes, realize the serialization of matrix, eliminate or alleviate stress collection
In.Therefore, selfreparing is realized, it is necessary to complete being sufficient filling with for liquid restoration confrontation crackle space of planes, to repairing material
There are certain requirement amount and repair process time.
Shape-memory polymer (SMP) is the polymeric material that a class has SME.Thermal drivers SMP is a certain
It can be deformed at temperature (being generally greater than glass transition temperature Tg), then keep shape invariance, be cooled to after room temperature and remove external force
Shape after deformation can be fixed and long-term storage, when temperature is increased into shape recovery temperature (rising of recovering of shape again
Beginning temperature is generally below Tg) after, the component after deformation can recover to original shape.It can be seen that, thermal drivers SMP is certain thermomechanical
In circulation, it can store and discharge strain energy, and complete the transformation of " initial state → stationary state → initial state ".
