    Influence of Sodium Polystyrene Sulfonate to Aging of Laponite Aqueous Suspensions
    (Видавництво Львівської політехніки, 2013) Savenko, Volodymyr; Bulavin, Leonid; Lebovka, Nikolai
    Laponite aqueous suspensions are widely used in science and industry. Recently polymer-Laponite composites attached great attention due to their remarkable physical properties. In present paper study of aging process of aqueous suspension of Laponite and sodium polystyrene sulfonate is described. For investigation two methods were used: smallangle X-ray scattering (SAXS) and small-amplitude oscillatory shear (SAOS) rheology. Concentration of Laponite were fixed at 2.5%wt and concentration of PSS-Na was varied in range 0-0.5 %wt.
