Title: | Synergism and antagonism in mixed monolayers: Brij S20/poloxamer 407 and Triton X-100/poloxamer 407 mixtures | Authors: | Dejan Ćirin Veljko Krstonošić Darija Sazdanić |

In this work interfacial behavior of Brij S20/P407 and Triton X-100/P407 surfactant mixtures was investigated. The nonideal behavior was elucidated by extending Clint's theory and by determination of the ideal maximum surface excess concentration values. Rosen's model for mixed monolayers was used to investigate interactions between different surfactants at the interface. Synergism was noticed in Brij S20/poloxamer 407 mixtures. However, very different interfacial behavior was observed for Triton X-100/poloxamer 407 systems. | URI: | https://open.uns.ac.rs/handle/123456789/1217 | ISSN: | 3783812 | DOI: | 10.1016/j.fluid.2018.06.009 |
