摘要
研究粘土矿物表面组成与表面结构的手段和方法多种多样，但由于粘土矿物特殊的晶体结构，这些手段和方法都有一定的局限性和不足。原子力显微镜是近年来发展起来的一种能达到原子分辨能力的表面结构分析仪器，能够分辨粘土矿物硅氧四面体片上的六方环结构及八面体片的羟基团，是研究粘土矿物表面反应、表面改性及表面溶蚀作用的重要手段。
There are many methods to study the surface component and structure of clay minerals, however these methods have different limitations. The atomic force microscope (AFM) is a recent innovation in instrumentation that provides topographic images, at the atomic scale resolution, of the surfaces of solid materials. It can image the hexagonal arrangement of basal O of the sheet of tetrahedra at molecular resolution and the OH plane of the sheet of octahedra at atomic resolution. It is becoming most important method to study the surface reaction, treatment and dissolve of clay minerals.
