摘要

Quantitative recording of the minute dynamic variation at an oil–water interface is always a great challenge. Dual polarization interferometry (DPI) presents an approach in monitoring the variations of mass, thickness, and density at the interface with high resolution. In this study, a planar crude oil–water interface was established by spin-coating on a DPI chip surface. Different concentrations of sodium dodecyl sulphate (SDS) and polyacrylamide (PAM) were injected into the interface. The absorption of free SDS molecules, in low concentrations, can be interpreted as a two-step absorption. With the existence of micelles in higher concentrations, the crude oil molecules tend to be taken away by the micelles. The absorptions of the polymers at the interface are different from SDS. The crude oil can hardly be taken away by the polymers. Instead, the hydrophobic segments of polymers insert into the oil film and hydrophilic groups stretch into the solution.
