Study of the micelle-to-vesicle transition and smallest possible vesicle size by temperature-jumps.
(2013) In Journal of Colloid and Interface Science 396(Online 1 February 2013). p.173-177- Abstract
- We have investigated the temperature induced micelle-to-vesicle transition in a binary non-ionic
surfactant/water system, for which the spontaneous curvature decreases with increasing temperature.
Temperature jumps with variable rate were performed in a microwave oven, from a micellar phase at
5 ◦C to a lamellar phase region at 35 ◦C, passing a liquid-liquid two phase region where dilute and
concentrated micellar solutions coexist. It is shown that the obtained vesicle size decreases with
increasing heating rate through this two phase region. Moreover, we demonstrate that there exists a
minimum vesicle radius, Rv∗, as is also predicted by theory. In the present system we find Rv∗ ≈ 50... (More) - We have investigated the temperature induced micelle-to-vesicle transition in a binary non-ionic
