| Abstract: | The interfacial behavior of rhamnolipids(RL) at the oil/water interface was studied using dissi-pative particle dynamics(DPD) method.The characteristic of the monorhamnose and dirhamnose rham-nolipids(R1 and R2) and their mixtures with conventional surfactants,such as sodium dodecyl sulfate(SDS),sodium dodecyl benzene sulfonate(SDBS) and fatty alcohol polyoxyethylene ether(AEO3) was studied.The interfacial behavior of R1 and R2 was studied and the effect of synergistic on the interfacial tension,interfacial... |
