Which dispersant is better to use to minimize van der Waals forces between powders?
To minimize the van der Waals effect between powders, the use of sterically hindered dispersants (e.g. polymers or graft copolymers) is a very good choice. They basically interrupt the intermolecular pulling by forming a physical barrier on the particle surface. The application will vary according to the dispersion medium (water or organic solvent) and the powder characteristics.
