dc.description.abstractUsing soft-contact AFM imaging, the adsorbed layer structure of mixed solutions of single-chained dodecyltrimethylammonium bromide (DTAB) and double-chained didodecyldimethylammonium bromide (DDAB) at varying compositions has been studied. On quartz, the observed morphologies as composition was varied from DDAB-rich mixtures to DTAB-rich mixtures changed from a bilayer -> mesh -> rods -> globules. This novel mesh structure is consistent with the average curvature progression from bilayer to rods, and consists of densely branched rods. There was a narrow solution composition over which this mesh structure was observed and a fractional change in solution composition resulted in a film transformation to rods. Neutron reflectometry experiments on multiple contrasts have been performed in ISIS and at ANSTO and confirm the curvature sequence observed using AFM. The composition of the mixed film was determined as were adsorbed amounts, film thicknesses and surface coverages. Despite there being an excess of DTAB in solution, the surface was very enriched in DDAB for the two mixed films. © 2005 The Authorsen_AU
