The foaming property of the aqueous mixtures of a fluorocarbon surfactant (FC) and a hydrocarbon surfactant (AOS) had been investigated. And the influence of polymer and oil on foam stability was studied systematically. Experimental studies indicated that AOS and FC surfactants had good cooperative effect. The foam stability could be remarkably improved with polymer and oil would impact the foam stability greatly. Mechanism on interaction between foam and oil for experimental foam systems was also studied quantitatively based on spreading coefficient. The effect of oil on the stability of polymer enhanced foams could not be fully understood by spreading coefficient. The increasing in viscoelasticity of foam films would play a key role in the stability improvement for polymer enhanced foams.
