Preparing Precise Polymer Solutions

Polymer solutions must be prepared with care. Special effort should be expended to ensure complete, homogeneous dissolution. The best method of obtaining correct concentrations is weighing the polymer and using volumetric flasks for solution volume. The second choice is weighing the polymer, then weighing the solution and using the density of solvent as an approximation […]

Colloidal Stability in Aqueous Suspensions

Why too much dispersant causes problems. Abstract Zeta potential in aqueous suspensions is a function of two variables: charge at the shear plane and free salt ion concentration. [Free here means not attached to the particle surface.] If a dispersant is added to increase the surface charge density (increase stability) and it’s too concentrated, the […]
