[Epub ahead of print]The thermoresponse of poly(di(ethyleneglycol) methyl ether methacrylate) (PMEO2MA) brushes has been investigated in the presence of monovalent anions at either end of the Hofmeister series using ellipsometry, neutron reflectometry (NR) and colloid probe atomic force microscopy (AFM). NR measurements in deuterium oxide showed no evidence of vertical phase separation perpendicular to the grafting substrate with a gradual transition between a block-like, dense structure at 45°C and an extended, dilute conformation at lower temperatures.
