Studied interactions of asphaltene and model naphthenic acid [stearic acid] at oil-water interface. Calculated and investigated excess work of compression for the asphaltene-acid mixed film from their Langmuir trough pressure-area isotherms. Identified a decrease in the rigidity of asphaltene interfacial film by stearic acid addition. Visualized morphology changes in asphaltene interfacial films with the increase in stearic acid amount using in situ Brewster angle microscope.
