The viscoelastic properties of lamellar liquid crystal, formed by non-ionic surfactant, were studied with small amplitude oscillation frequency sweep, and the effects of surfactant concentration, temperature , AgNO3 and as-produced Ag on them were investigated. The results show that, storage modulus (G′) and loss modulus(G″)increase with increasing surfactant concentration; three different kinds of frequency sweep curves appear with increasing temperature; AgNO3 and as-produced Ag have no effects on the shape of curves, but their effects on the magnitude of G′and G″are different for transitional and pure lamellar phases.
