摘要：The lyotropic ferromagnetic liquid crystal contains:… &cirf& 1% to 90% byweight of a surfactant,… &cirf& 1% to 90% by weight of a cosurfactant,… &cirf& 1% to97% by weight of oil,and… &cirf& 1% to 97% by weight of a polar liquid.… …The ratio ofthe mass of the cosurfactant to that of the surfactant is less than 2. The four constituentsform elongated aggregates (7) dispersed in a continuous liquid phase (5), the length (l) ofthe aggregates being greater than the distance (d) separating two consecutiveaggregates (7). The aggregates enclose ferromagnetic particles (9). ……
