ADSORPTION OF COMB MACROMOLECULE ON FUSED -SILICA PARTICLES AND THE CALCULATION OF INTERPARTICLE POTENTIAL-ENERGY

We have discussed the effect of comb macromolecule adsorbed on fused s ilica particles to the dispersion of the particle. The effect of the a mount and thickness of the polymers adsorbed on the fused silica parti cles on the total interparticle potential energy was investigated. The evaluation of dispersed property of the particles in solvent was cons idered by magnitude of interparticle potential energy. The total inter particle potential energy was calculated by summing up the steric hind rance effect and London-van der Waals interaction. The amount of polym ers adsorbed were not influenced by the minimum of the total potential energy. The maximum radius of the particles that can be dispersed in polymer solution was in proportion to the thickness of the adsorbed la yer.
