Abstract
The present invention relates to a method of forming shape-retentive aggregates of gel particles in which the aggregates are held together by non-covalent bond physical forces such as, without limitation, hydrophobic-hydrophilic interactions and hydrogen bonds. The method comprises introducing a suspension of gel particles in a polar liquid at a selected concentration, wherein the gel particles have an absolute zeta potential, into a medium in which the absolute zeta potential of the gel particles is decreased, resulting in the gel particles coalescing into the claimed shape-retentive aggregate. This invention also relates to uses of the method of formation of the shape-retentive aggregates of gel particles.
