文摘
The tensiometry and foam experiments shed light on the surface behavior of SDS-hydrophilic silica nanoparticle dispersions. The surface tension and the foam properties of SDS solutions are considerably improved in presence of silica particles. The surface adsorption of nanoparticles can be evaluated by applying high amplitude compressions/expansions protocols. Standard deviation of drop shape from Laplacian form is a powerful tool for evaluation of complexes structure at interface.
