Spherical micelle formation by mixed quaternary ammonium surfactants with long, and short, tails in ethanol/water solvent and micellar freezing upon solubilising styrene polymerisation
The association of mixed docosyltrimethylammobium bromide and octadecyltrimethylammonium bromide, C22TABr/C18TABr, in ethanol (a common solvent favoured for both their alkyl tails and head-groups) induced by the addition of water (a non-solvent for the tails) has been studied using light-scattering measurements. Under the assistance of NaBr, which promoted the surfactant molecules to pack tightly in the micelles, mono-disperse spherical micelles composed of mixed C22TABr/C18TABr were obtained in ethanol/water (15/85?wt%). Styrene was solubilised into the templating C22TABr/C18TABr micelles (betasurf, the molar ratio of C18TABr to C22TABr, was 2.5) and then was polymerised in situ. To achieve a good freezing effect, the amount of styrene solubilised, represented as the molar ratio of styrene monomer to total surfactants, nst/nsurf, was required to be greater than 4.87 for this templating micellar system. The diluting tests demonstrated that, after polymerisation, the styrene-containing micelles froze their microstructure well. Light-scattering measurements, and TEM observation, all indicated that these micelles were mono-dispersed, and retained their spherical shape. As swollen by polystyrene, the micelle had an avarage radius of 18?nm.
Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.COA of Formula: C21H46BrN, you can also check out more blogs about1120-02-1
