摘要：

Nematic lyomesophases in the systems sodium decyl sulfate (SDS)/water/decanol/Na2SO4 and potassium laurate (KL)/water/KCl, which form respectively Nd (discotic) and Nc (cylindrical) phases, have been studied. Measurements of the critical magnetic field for the Freederickzs transition allowed determination of kii/χa as a function of temperature; χa is the diamagnetic anisotropy and kii is an elastic constant (splay k11 for Nc and bend k33 for Nd phases). The results might indicate that micelles behave as flexible objects. © 1990 American Chemical Society.
