Abstract

The knowledge of the surface properties of layered minerals is of great importance to understand basic and applied technology, such as, for example liquid/surface interactions, microfluidity, friction or tribology and biomolecules self-assembly and adhesion. Recent developments of Scanning Probe Microscopy (SPM) have widened the spectrum of possible investigations that can be performed at a nanometer-scale level on the surface of minerals. Investigations involve physical properties, such as surface potential and electric-field topological determinations, and chemical and spectroscopic analysis in air, in liquid or in a gaseous environment. After a brief introduction of new technological developments relating to SPM, recent achievements are presented in characterization and application of nanomorphology and surface potential properties of minerals, in particular the behaviour of some layer silicates. Two general research directions are presented: application of bio/organic surface interactions of layer silicates, and mineral hydrophilicity/phobicity and friction/adhesion issues.
