Abstract

The electrical resistances of poly(N-isopropylacrylamide), poly-(NIPA), upon thermal phase transition between the swollen hydrogel (20°C) and solid (40°C) states are analyzed by Faradaic impedance spectroscopy, chronopotentiometry, and cyclic voltammetry. The incorporation of Au-nanoparticles into the poly-(NIPA) by a thermal "breathing-in" process, reduces the electron transfer resistance in the solid composite material.
