Structure and electric properties of SDS/BA/H2O system

The results of determination of the conductivity, the association degree of counter - ion and the capacitance indicate that their values are relativel y small in the O/W microemulsion for SDS/BA/H2O system. At the constant wei ght ratio of SDS to water, the conductivity, the association degree of coun ter - ion and the capacitance first increase up to the maximum and then beg in to decrease with BA content increasing. In the bicontinuous region, ther e is a chain conductive mechanism. The conductivity, the association degree and the capacitance change scarcely with the water content. The relation o f the capacitance with the properties of physical chemistry in O/W spherica l microemulsion region by a least - mean square method is C/mu F = 1.036 x 10(-8) (1 - beta) Z(8)kappa D-1 + 0.03466 epsilon(1)chi(1) - 0.09677 epsilo n(2)chi(2).
