Charge Distribution and Interaction Forces at Interfaces: High Resolution Detection and its Application towards the Controlled Formation of Mesoscopic Structures (C04)

• Subject Area: Physical Chemistry of Solids and Surfaces, Material Characterisation ; Analytical Chemistry
• Term: from 2011 to 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 79971943

In project C04 new probe microcopy methods will be developed for studying the interaction between single building blocks of mesoscopic systems. The inter-particle force and adhesion of nanoparticles are of particular interest for the industrial applications of colloidal suspensions. To measure such interactions, we will develop on the base new instrumental approaches on the base of a combination of atomic force microscopy (AFM) and nanofluidics. With the same setup, also the interaction force in other colloidal systems can be determined quantitatively, for example during the exfoliation of silicate platelets. for the preparation of colloidal probes that are used in direct force measurements with the atomic force microscope (AFM). Electrostatic forces due to local charge distributions are particularly long-ranged. Therefore, those will be studied closely by other probe microscopy techniques.
