Abstract

The effects of temperature and methanol concentration on the properties of poly(N-isopropylacrylamide) (polyNIPAM) at the air/solution interface were studied. It was shown that when the methanol concentration is above 65%, the surface concentration of polyNIPAM is essentially zero. It was also shown that the second adsorption regime occurs at lower alcohol concentrations and at temperatures below the lower critical solution temperature (LCST). The third adsorption regime occurs above the LCST where thick layers form the deposition of phase-separated polyNIPAM at the air/solution interface.
