Interaction force measurements were performed for a silica-silica hydrophilic system and for a silanated silica-silanated silica hydrophobic system using the atomic force microscopy colloidal probe technique. The influence of the solution composition on interaction forces was investigated. The hydrophilic silica-silica interactions were found to be described as a typical Derjaguin-Landau-Verwey-Overbeek (DLVO) system in solutions of various compositions, whereas silanated silica-silanated silica interactions were dominated by a long-range hydrophobic force. An increase in the isopropyl alcohol content of the solution diminishes both the repulsive forces in the case of the hydrophilic system and the attractive interactions in the case of the hydrophobic system.
使用原子力显微镜胶体探针技术对硅-硅亲水性体系和硅烷化硅-硅烷化硅疏水性体系进行了相互作用力测量。研究了溶液组成对相互作用力的影响。结果表明，在各种组成的溶液中，亲水硅-硅相互作用可以用典型的德贾金-朗道-范德华-奥弗贝克（DLVO）体系来描述，而硅烷化硅-硅烷化硅相互作用则主要由长程疏水力主导。随着溶液中异丙醇含量的增加，亲水性体系中的排斥力和疏水性体系中的吸引力都会减小。
