The surface-functionalised polymeric object can be produced in a one-step procedure by coaxial electrospinning.

Shape memory polymers allow the fabrication of objects that have a permanent (first) shape, and which can be programmed to adopt a temporary (second) shape, and are able to largely recover their original (first) shape by applying an appropriate stimulus. Materials that permit the fabrication of objects and devices that can (i) be provided in their permanent shape, (ii) be heated to a switching temperature above physiological temperature, at which the material becomes shapeable, (iii) be inserted into the body or placed in contact with the body and be deformed or shaped”to assume a desired temporary shape, (iv) be fixed in the desired temporary shape by keeping the material/device/object at body temperature (about 37° C.) for a convenient period of time, (v) largely retain this temporary shape if removed from the body, and (vi) return largely to their original shape when heated again above the switching temperature. A process for making such materials and disclosed products based on such materials are disclosed.
