Article Preview

Surfactant hydrogels were prepared composed of sodium dodecyl sulphate(SDS) /Al(NO3)3 /H2O systmes. Steady and oscillatory shear experiments were carried out to evaluate the inner structure of the gel with variable Al(NO3)3 concentration at a fixed SDS 20wt% composition in gel region. The results indicated that hydrogels showed shear-induced thinning nonlinear rheology behaviors. Phase transition was measured by differential scanning calorimetry and the transition temperature(Tgel) increased with aluminum salt concentration increasing. It is in conformity with electron micrograph of microstructures from spherical, short rod-like to larger cylindrical micelles. Littler salt change resulted in larger micelles transition derived from supramolecule structure of SDS and Al3+.
