Rod-like micelles of octadecyltrimethylammonium bromide and their freezing upon solubilised styrene polymerisation

Abstract

C18TABr formed rod-like micelles in ethanol/water (10/90 wt%) with the assistance of SNphs and styrene was then solubilised and polymerised in situ, by which means the mono-dispersed, rod-like micelles were frozen.

“…29 a Likewise, salt addition or the presence of additional counter ions induce the formation of lower-curvature surfaces, causing shape changes from globular to worm-like micelles. 29 These morphological changes mostly originate from electrostatic and hydrophobic interactions between cationic surfactants and anionic counter ions. These interactions suppress the micellar charge and decrease the surface area per surfactant molecule by reducing the electrostatic repulsion between head groups.…”
