Model bicontinuous microemulsions in ternary homopolymer/block copolymer blends

Article Abstract:

A study was conducted to examine a channel of bicontinuous microemulsion in three chemically different homopolymer/hompolymer/block copolymer ternary bends. The phase diagrams of the three systems, which were created using small-angle neutron scattering, rheology and cloud point measurements show that a common region in phase space exists where bicontinuous microemulsion is stable. In addition, it was also observed that the polymeric systems' general phase behavior is not affected by polymer molecular weight.

Ternary polymer blends as model surfactant systems

Article Abstract:

An investigation of the ternary phase prism for low molecular weight poly(ethylene oxide), squalane, and poly(ethylene oxide-b-ethylenepropylene) is presented. A rich phase diagram was revealed, including most of the equilibrium liquid crystalline phases associated with diblock copolymers, regions of two-phase and three-phase coexistence, and a bicontinuous microemulsion.

Clusters in polymer-surfactant AOT microemulsions probed by excited state quenching kinetics

Article Abstract:

The studies were done where excited-state quenching kinetics were applied to sodium 1,4-bis(2-ethylhexyl)sulfosuccinate (AOT) reversed miscelles with poly(oxy)ethylene (POE) where clusters were previously detected. The results confirm the validity of the data treatment used in the nanosecond range.
