Abstract
The aggregation behaviors of a series of dissymmetric cationic Gemini surfactants,[C m H2 m+ 1 (CH3) 2N (CH2) 2N (CH3) 2C n H2 n+ 1] Br2, designated as m-2-n (with a fixed m+ n= 24, m= 16, 14, 12) have been investigated in a protic ionic liquid, ethylammonium nitrate (EAN). Surface tension, polarized optical microscopy (POM), small-angle X-ray scattering (SAXS), and rheological measurements are adopted to investigate the micellization and ...
