Clay colloids
Webadjacent to the clay surfaces by the ethylene oxide segments on the PEO backbone [14]; the ether oxygens of PEO act as Lewis bases and have a high affinity for the silica on the clay surface, which act like Bro¨nsted acids. Since the pH of the laponite suspension is quite high (pH / 10.0), there is competition between the hydroxyls and the poly- WebThe colloidal clay particles have inner ionic layer (surfaces of highly negative charge) and the outer ionic layer (cations swarming layer).
