DIRECT DETERMINATION BY NEUTRON REFLECTION OF THE STRUCTURE OF TRIETHYLENE GLYCOL MONODODECYL ETHER LAYERS AT THE AIR-WATER-INTERFACE

Abstract:

Neutron reflectivity with isotopic substitution has been used to determine directly the structure of triethylene glycol monododecyl ether adsorbed at the air-water interface. The surface excess has been measured from concentrations ranging from twice the critical micelle concentration (cmc) (=5.5 × 10-5 M) to one fiftieth the cmc. The results are in good agreement with those from surface tension measurements and show that the area per molecule tends to a limiting value of 36 Å2. The structure...
