The discovery and investigation of new phenomena can be based on random or even designed structures that are capable of stimuli-responsive features with intrinsic or extrinsic materials properties. Polymers can be designed on the molecular level to have their intrinsic features a part of the process. However, the processing conditions or the layer order can have an unconventional effect on the properties of these materials as well in the presence of field stimuli. In this talk, we will focus on interfaces, particles, and microparticles accessed by layering and polymer grafting to enable chemo-responsive properties observed by actuation and swelling. This will be based on polymer particles process through lithographic and non-lithographic methods. We demonstrate the following systems: 1) Bilayer based folding origami-like structures via folding of reactive ion etched patters and multilayer assemblies, 2) CLiPS polymer extruded polymer layers capable of swelling and incorporation of dyes to enable controlled release, 3) Fabrication of smart multilayer surfaces capable of controlled wetting and separation. We report the general principles as well as the possiblities for actual applications.
