本文报道了一种新的毛细管诱导相分离（CIPS）的观察结果，我们认为它具有相当大的实际意义。在糊精和聚环氧乙烷的半稀混合水溶液中，云母之间存在着一种远距离的吸引力。结果发现与报道的液体混合物中的CIPS相似，并且远程线性力的来源可能与形成具有不同于混合聚合物体溶液的聚合物组成的毛细管冷凝物有关。
Observations of a novel case of capillary-induced phase separations (CIPS), which we judge to be of considerable practical significance, is reported. A long-range attractive force was observed between mica in mixed aqueous semidilute solutions of dextran and poly(ethylene oxide). The result was found to be similar to reported CIPS in liquid mixtures, and the origin of the long-range linear force can be related to the formation of a capillary condensate with a polymer composition different from the mixed polymer bulk solution.
