摘要：

A series of coagulation experiments conducted on aqueous suspensions of methylated silica provides evidence that non-DLVO interaction energy controls the stability. This additional energy, which may be referred to as the hydrophobic interaction energy, can be estimated from the results of coagulation experiments. An expression has been derived to describe the hydrophobic interaction energy in terms of the nondispersion component of work of adhesion of water and the distance between two interacting particles. © 1990.
