The interaction in water of neutral hydrocarbon and fluorocarbon surfaces, prepared by Langmuir-Blodgett deposition of surfactant monolayers, has been investigated. The attraction between these hydrophobic surfaces can be measured at separations of 70 to 90 nanometers and thus is of considerably greater range than previously found. Spontaneous cavitation occurred as soon as the fluorocarbon surfaces were brought into contact but occurred between the hydrocarbon surfaces only after separation from contact. The very long range forces measured are a consequence of the metastability of water films between macroscopic hydrophobic surfaces. Thus the hydrophobic interaction between macroscopic surfaces may not be related to water structure in the same way that the hydrophobic effect between nonpolar molecules is related to water structure.
已研究了通过表面活性剂单层的 Langmuir-Blodgett 沉积制备的中性烃和氟碳表面在水中的相互作用。这些疏油表面之间的吸引力可在 70 至 90 纳米的间隔处测量，因此其范围比以前发现的要大得多。氟碳表面一接触就会发生自发空化，但烃表面只有在分离接触后才会发生。所测量的长程力是宏观疏油表面之间的水膜亚稳性的结果。因此，宏观表面之间的疏水相互作用可能与水结构无关，就像非极性分子之间的疏水效应与水结构有关一样。
