pH and temperature sensitive poly(N-isopropylacrylamide) (pNIPAm) microgel-based etalons were fabricated by sandwiching a “monolithic” microgel layer between two semitransparent, 15 nm Au layers. The devices exhibit visual color and multipeak reflectance spectra, both of which primarily depend on...

In this submission we fabricated a humidity-responsive polymer-based actuator by layering negatively charged poly(N-isopropylacrylamide)-co-acrylic acid microgels and positively charged poly(diallyldimethyl ammonium chloride) on top of a flexible plastic substrate. We show that the extent of the...

Responsive polymer-based materials (or smart materials) have found numerous uses over the years due to their ease of synthesis and various responsivities/functionalities. Of them, stimuli-responsive hydrogel particles (microgels) have generated a lot of interest, and have been used for a number...

This letter describes a new method for fabricating supramolecular microgels from supramonomers. To this end, we designed and assembled supramonomers with one acrylate moiety on each end on the basis of noncovalent host–guest interactions, which could be utilized as a cross-linker. Then...
