정전기적으로 분산된 콜로이드 실리카 입자의 코팅 = Coating of Electrostatically Dispersed Colloidal Silica Particles

다국어 초록 (Multilingual Abstract)

Spherical colloidal particles of silica in 0.1㎛ diameter were synthesized dispersed in water electrostatically by adjusting pH. The particles in suspensions were deposited using dip-coating on a soda-lime glass substrate. Total potential energy between the particles and the substrate was calculated and the result was discussed with the adhesion and arrangement of the deposited particles.
Particles deposited from a suspension of pH=4 were removed after washing with deionlzed water due to the flocculation of the particles arising from an attraction force between the particles. Deposition of a suspension of pH=8 resulted in a dense coating that the particles were uniformly adhered. Whereas, the deposition with a suspension of pH=6 resulted in a realtively porous coating that the particles were less uniformly adhered. The dense and uniform packing of the particles was attributed to a repulsion force existing between the particles.
