Abstract: Methods to control the flow behavior of non-Newtonian materials are described. Methods can increase the shear-thinning behavior of non-Newtonian materials such as aqueous suspensions, polymer melts and solutions, etc. Methods include induction of electrostatic charges to the surface of particles, e.g., nanostructures, held in suspension in the materials. The suspensions include different types of particles having different point of zero charge. Electrostatic charges are induced through adjustment of the pH of a suspension containing the particles, thereby modifying rheological characteristics of the material.
