Abstract
Observations of a novel case of capillary-induced phase separations (C IPS), which we judge to be of considerable practical significance, is reported. A long-range attractive force was observed between mica in m ixed aqueous semidilute solutions of dextran and poly(ethylene oxide). The result was found to be similar to reported CIPS in liquid mixture s, and the origin of the long-range Linear force can be related to the formation of a capillary condensate with a polymer composition differ ent from the mixed polymer bulk solution.
