The surface characteristics, including surface charge and wettability, of layered silicates are reviewed based on experimental results and molecular dynamics simulation (MDS) results. The surface charge features of important layered silicates including mica, talc, and kaolinite are described from atomic force microscopy (AFM) measurements, electrophoresis measurements, and/or results from potentiometric titration. In addition, the wetting characteristics of the silica tetrahedral surface which is common to all layered silicates are examined with different experimental techniques and results are discussed. The wettability of trilayer silicates and bilayer silicates is discussed, particularly the wettability of the silica tetrahedral face and alumina octahedral face of kaolinite based on MDS results as well as recent AFM results.
基于实验结果和分子动力学模拟（MDS）结果，综述了层状硅酸盐的表面特性，包括表面电荷和润湿性。从原子力显微镜（AFM）测量、电泳测量和/或等电滴定结果描述了云母、滑石和高岭土等重要层状硅酸盐的表面电荷特性。此外，还使用不同的实验技术研究了所有层状硅酸盐共有的硅四面体表面的润湿性，并讨论了实验结果。讨论了三层硅酸盐和双层硅酸盐的润湿性，特别是基于 MDS 结果以及最近的 AFM 结果讨论了高岭土的硅四面体面和氧化铝八面体面的润湿性。
