We introduce a novel approach to control interdrop association of attractive nanoemulsion (ANEs) by utilizing polymer chain conformation changes of attractive micellar linkers (AMLs). Highly stable ANEs were fabricated by co-assembly of amphiphilic triblock copolymer, poly(ethylene oxide)-b-poly(ε-caprolactone)-b-poly(ethylene oxide) (PEO-b-PCL-b-PEO), with lecithin to form a resilient membrane at the oil-water interface. AMLs were prepared by hybridizations of the triblock with lecithin to led drop-linker-drop association though dipolar attraction. The attraction between lecithin head on hydrophobic core of AMLs with end group of PEO enables to control the association. From dense suspension rheology studies, we demonstrated that the properties of polymer dominate the rheological properties of ANE systems. Finally, evaluations of this nanoemulsion fluid system on cell membrane-mimic layer propose potential for soft-material application. |
