Johnson, Kai C. C., Mendez, Francisco, Serpe, Michael J.
Poly (N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgel-based etalons have been shown to have visible color and unique spectral properties, which both depend on solution temperature and pH. In this investigation, pNIPAm-co-AAc microgel-based etalons were fabricated on the Au...

Poly(N-isopropylacrylamide) (pNIPAm) microgel-based etalons were used to fabricate systems that change visual color in response to light exposure. These systems were fabricated by adding pH responsive microgel-based etalons to a solution composed of the photoacid o-nitrobenzaldehyde (o-NBA). Upon...

Parasuraman, Deepika, Sarker, Avijeet K., Serpe, Michael J.
Poly (N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgels and their aggregates have been shown to effectively remove organic dye molecules from aqueous solutions. Here, we investigate the reusability of these microgel-based systems by exposing them to the organic azo dye molecule,...

Li, Xue, Gao, Yongfeng, Serpe, Michael J.
Poly(N-isopropylacrylamide) based hydrogel particles (microgels) crosslinked with N,N′-bis(acryloyl)cystamine were prepared using free-radical precipitation polymerization. By coating a single layer of microgels on a gold-coated glass substrate followed by the addition of another gold layer, an...

The influence of deposition solution pH and ionic strength on the quality of poly (N-isopropylacrylamide) microgel-based thin films and etalons
Download2013-01-01
Poly(N-isopropylacrylamide)-co-acrylic acid (pNIPAm-co-AAc) microgel-based thin films and etalons were fabricated via “painting” a pNIPAm-co-AAc microgel monolayer on a Au-coated substrate, followed by the deposition of another Au overlayer. Herein, in situ observation of how the pH and ionic...
