Amphiphilic association structures and some aspects of foam stability

This investigation was performed in order to study two interesting and important problems in foams. Foam separation was studied in the model system of water - sodium octylsulfonate - decanol. The efficiency of foam separation as a function of surfactant concentration and decanol content were measured. The results were related to the association structures of amphiphiles in aqueous systems. Foam polymerization was conducted in the amphiphilic system containing water, polymerizable surfactant and oleyl alcohol. Liquid foams were produced in one three - phase region. The location and optical pattern of liquid crystals on the foam surface were observed by photomicroscope with polarized light. Solid foams were obtained when the liquid foams polymerized. The investigation was successful. The effect of amphiphile association structure on foam separation was established. The polymerized foam obtained in this study showed a novel development in solid foams --Abstract, page iv
