There are several forces that can occur between two materials. They are
really all the same, electronic attraction caused by various processes.
In non-polar materials, the solvation comes from Van der Waals forces
that occur when molecular election clouds have finite periods of
inhomogeneity. This temporary electron cloud distribution causes small
partial negative and positive regions, thereby permitting electronic
attraction between otherwise non-polar molecules.
