NEUTRON REFLECTION FROM HEXADECYLTRIMETHYLAMMONIUM BROMIDE ADSORBED AT THE AIR/LIQUID INTERFACE - THE VARIATION OF THE HYDROCARBON CHAIN DISTRIBUTION WITH SURFACE CONCENTRATION

Abstract:

We have determined the structure of a monolayer of hexadecyltrimethylammonium bromide adsorbed at the air/water interface at its critical micelle concentration (9.2 × 10-4 M) and at two lower concentrations using neutron specular reflection. We have used isotopic labeling to determine the relative positions of chains, heads, and solvent, and more detailed labeling to determine the distributions of C6 chain fragments at either end of the alkyl chains. The use of the more detailed labeling sche...
