Adjustable volume and loading release of shape memory polymer microcapsules

Research on microcapsules has been conducted in recent years given trends miniaturization and novel functionalization. In this work, we designed prepared a series of unique shape memory polyurethane (SMPU) with stimuli-responsive functions. The microcapsule core-shell structure which the surface morphology can be adjusted, it certain load-bearing capacity. addition, SMPU function for solvent response. temperature its recovery is approximately body temperature, swell to rupture under stimulation organic solvents. Thus, potential applications biomedical fields, such as drug release.
