Molecular dynamics study of the molecular weight dependence of surface tensions of normal alkanes and methyl methacrylate oligomers

Surface tensions (gamma) of normal alkanes and methyl methacrylate (MMA) oligomers at various molecular weights in the low molecular weight range are calculated using a new molecular dynamics simulation strategy. The MD simulations, even with the use of a generic force field, reproduced the experimentally observed molecular weight dependence of gamma for both series of oligomers.
