Description
Technical Field
The invention relates to the technical field of high polymer materials, in particular to a shape memory material and a preparation method thereof.
Background
Shape memory materials are composite materials that exhibit at least two forms, one form being a distinct permanent shape and the other form being a temporary or fixed shape. The temporary or fixed shape forms or attenuates the most common thermal transitions, such as glass transition or melting. The temporary shape is achieved by exposing the shape memory material to an external stimulus (most commonly heat) such that the components of the shape memory material are present above their transition temperature (rubbery or molten state). Deformation in the rubbery or molten state and subsequent cooling at the transition temperature under an applied stress fixes the temporary shape by vitrification or crystallization of the rubbery or molten shape memory material component. Subsequent exposure to an external stimulus causes the shape memory material to return to the original permanent shape.
Most shape memory materials exhibit dual shape memory properties with two form factors (permanent and temporary); however, some shape memory materials have more than one temporary shape, referred to as triple shape memory. This is particularly useful for medical and aerospace applications where the ability to work in confined spaces is highly desirable. Furthermore, shape memory materials have the unique ability to be remotely activated to avoid damage to the surrounding environment during actuation and deployment. Heat, IR and UV light, electrical current, magnetic fields, chemicals and moisture contact can be the stimuli that trigger shape recovery.
A balance between the weight ratio of the memory and switching networks is necessary to produce a shape memory material with good shape fixation and good shape recovery. The high hardness segment component produces good recovery; however, the shape fixing property is affected. Therefore, there is always a compromise between shape fixation and recovery. Current shape memory polymers are typically copolymers specifically synthesized for use as shape memory materials. This requires a deep, time consuming, solvent intensive process to produce the shape memory material, after which additional solvents are typically used to cast or coat the film of shape memory material. These treatments involve the use of large amounts of flammable and toxic organic solvents, which are often expensive. Furthermore, these solvents are expensive not only in purchase but also in placement of the last part of the shape memory material processing. In many cases, solvent costs (including initial solvent purchase, solvent processing equipment, and solvent disposal equipment and processes) are significant costs for the manufacture of polymers for shape memory applications.
The copolymers used are generally based on polyurethanes, polyethers and polyesters; however, the combination of co-agglomerated masses for shape memory polymers is endless, large quantities of shape memory materials are not produced in large quantities and/or are not commercially available, resulting in expensive manufacturing processing costs.
