Negative surface viscosities in fluid-fluid interfaces with adsorbed insoluble surfactants
Recent measurements of the surface viscoelasticity of liquid surfaces with adsorbed surfactant using surface light scattering have yielded negative dilational viscosities (ε’ < 0). In this paper, we present a physical explanation for this phenomenon by constructing a molecularly based theory for...
