Molecular structure and stability of the sorbitan monostearate (Span60) monolayers film at the water-air interface: A molecular dynamics simulation study

Sorbitan monostearate (Span60) molecules adsorbed on the water surface were investigated using a classical molecular dynamics technique. This study reveals that the formation of a Span60 monolayer film is more stable over a wide range of temperatures. Hydrogen bonding plays a crucial role for the film stability.
