The Role of Polymers in the Stabilization of Disperse Systems

  • D. H. Napper


Nonionic polymers can impart stability to a colloidal dispersion in at least two different ways:
  1. (i)

    if attached to the colloidal particles, they can generate steric stabilization;

  2. (ii)

    if free in solution, they may generate depletion stabilization.
