Through the addition of charged nanoparticles to colloidal dispersions of microparticles, the viscosity of the dispersion is modified. By tailoring the potential difference between the microparticles and nanoparticles, the pH, and the amount of nanoparticles added, the phase of the dispersion may be controlled. Through the disclosed methods, colloid flocculation is controlled and colloidal crystals may be isolated. |
