| Abstract: | It is conjectured that anionic-cationic surfactant combination can be regarded as equivalent to a double chain surfactant
and using molecular packing considerations it is shown that vesicles, viscoelastic solutions and liquid crystals can be designed
by the proper choice of chain lengths of the pair. Using these concepts new systems are designed, from mixtures of cetyltrimethyl
ammonium bromide and sodium alkyl sulfonates, to produce both viscoelastic gels and vesicles. |
