The structures of micelles of alkytrimethylammonium perfluorocarboxylates and of their adsorbed layers at the air/water interface

Abstract:

The structures of adsorbed layers of dodecyl (C12)- and hexadecyl(C16)-trimethylammonium perfluoroacetate, perfluoropropionate and perfluorobutyrate have been studied at the air/water interface by neutron reflection. In general, as the size of the fluorocarbon counterion increases the surfactants become more surface active, as manifested by the values of the critical micelle concentration (c.m.c.). However, the area occupied per surfactant ion pair increases with size of the perfluoro counter...
