Micron Sized Polyurethane Shape-Memory Polymer Beads

Abstract:

We demonstrate a novel approach to produce micron sized shape-memory beads from polyurethane shape-memory polymer (SMP)-dimethylformamide (DMF) solution by joule heating carbon fibers. The relationship between the geometrical dimensions of the resultant SMP beads and processing condition is obtained, which shows the convenience in dimension/size control in fabrication. The fabrication mechanism is revealed and good shape-memory effect is proved.
