Description
Technical field
The present invention relates to polymer arts, and in particular, to a kind of polymer blend, the preparation side of the polymer blend
Method, the application of the polymer blend being prepared by this method and the polymer blend in shape-memory material.
Background technique
Shape-memory material is a kind of special intellectual material.Shape memory metal has many in industry and life
Using, for example, Philips Corporate can only tire stud, can be extended automatically in icy road, improve the skid resistance of tire
Energy.Italian a company develops the clothes containing shape-memory material, and sleeve can automatic roll up when same day heat.In space
The antenna of some satellites is also made of shape memory type metal.Shape-memory material is most typical in terms of shape memory effect to answer
With being exactly shape memory pipe fitting.Shape memory pipe fitting can connect two pipelines, and especially two size differences are very big
Pipeline.Shape memory pipe fitting has many advantages, such as that high reliablity, structure are simple, easy for installation, saves assembly space.Shape memory
Material is often applied to particular surroundings demand, or the field of hommization, usually has the characteristics that high added value, is that one kind can not
The new material of substitution.
After thermotropic induction type shape-memory material undergoes initial figuration, deformed at a certain temperature by external force, it is cooling
After be able to maintain deformed shape；And after heating again, it can return to the original form.There is shape memory type macromolecule processing to hold
Easily, light weight, low operation temperature and the advantages such as cheap, therefore often there is it to be applied in the industry of many high added values
Research.The high molecular largest deformation rate of shape memory type is usually between 10-100%.
Shape memory type macromolecule is divided into reversible and two kinds irreversible.Irreversible shape memory type is high molecular initially
Shape can not be changed Yi Dan assigned, and reversible shape memory type macromolecule, its initial figuration is changeable, more ring
It protects.
For irreversible shape memory type high molecular material, for example, CN103160948A discloses one kind based on crosslinking
Shape memory high molecule.Its deformation fixed rate is about 90-98%, and shape recovery rate is between 85-95%.This kind of shape note
Recall high molecular initial figuration it is all not reproducible and regeneration.Also, their deformation fixed rate and shape recovery rate and 100% are all
There is a certain distance.Their largest deformation rate is usually between 20%-400%.And for reversible shape memory type high score
Son, for example, a kind of shape memory high molecule that CN105504474A is disclosed, its shape recovery rate is 80-95%, and shape is fixed
Rate is about 90-98%, and largest deformation rate is about 50%.Although initially figuration is repeatable for this kind of shape memory type macromolecule, it
Shape recovery rate and shape fixed rate be often not so good as irreversible shape memory type macromolecule, and largest deformation rate is worse
It is more, typically less than 100%.Currently on the market there is no one kind can big deformation, and shape recovery rate and shape fixed rate
All close to 100% reversible shape memory-type macromolecule.
