The stimulus used for fixing and releasing the temporary shape will thus depend on the choice of the latter. Most shape memory polymers studied so far respond to a change in temperature, but many alternative switching schemes have been developed where the shape memory effect is driven by exposure to light, chemicals, or other stimuli. high performance stimuli-responsive polymeric materials. This review focuses on recent developments in the preparation and application of patterned stimuli-responsive polymers, including thermoresponsive layers, pH/ionic-responsive hydrogels, photo-responsive film, magnetically-responsive composites, electroactive composites, and solvent-responsive Stimuli-responsive polymers undergo a change in their physical properties in response to a given physical or biological stimulus.

ABSTRACT: Stimuli-responsive star polymers gain more and more interest over the last decades due to their unique proper-ties compared to their linear counterparts. The branched struc-ture for instance has influence on the responsive behavior of these polymers. This review offers an overview of stimuli-re-

The ideal drug delivery system is the one in which the drug delivery profile is able to respond to metabolic states and/or physiological variations (Bawa et al., 2009). This kind of Given these unique properties, stimuli-responsive polymers are being developed for use in such fields as drug delivery, cell adhesion, sensors, actuator systems, releasing of encapsulated materials and trafficking of molecules through polymeric membranes [18–23]. The “response” of a polymer can be defined in various ways.
