Molecular Simulations of Ultrathin Perfluoropolyether Films under Shear

摘要

In this project dealing with aqueous films confined between solid surfaces atspacings comparable to the molecules themselves, we succeeded, for the first time, to investigate the effect of deformation frequency and amplitude on the shear dynamics of these films. We also succeeded, for the first time, to observe molecular ordering of aqueous ions at the solid-liquid interface. These unique experiments not only open new directions in research on liquids in confined geometries, but also have important implications for the field of tribology.
