Poly(N-isopropylacylamide) (pNIPAM) has temperature-responsive property that it collapses when heated above the lower critical solution temperature (LCST) in water. Due to their unique features, pNIPAM-based microgels have been suggested as promising materials in several potential applications such as drug delivery, biosensor and chemo-mechanical devices. In this study, we designed pNIPAM microgel which is not only thermoresponsive but also capable of self-assembly with terpyridine (tpy) ligand-metal interaction to generate polymer nanostructures. Tpy was functionalized on the surface and inside of pNIPAM microgel particles. We confirmed that the resulting microgel particles can self-assemble in the presence of metal ions. Furthermore, we can show self-assembled polymer thin films by Layer by layer (LbL). Assembled nanostructures of tpy-pNIPAM microgels were characterized by scanning electron microscopy (SEM), dynamic light scattering (DLS) measurement and UV-Vis spectroscopy. |
