Electrophoretic Deposition Mechanism of Mesoporous Silica Powder in Acetone

Abstract

The preparation of a thick coating of mesoporous silica (MPS) on metal substrates by electrophoretic deposition (EPD) has been studied for application to an advanced desiccant cooling system. In this study, we investigated the EPD mechanism of MPS in acetone under a constant applied voltage for the fabrication of a thick MPS coating. We consider that the main contributors to the resistance between the deposition electrode and the counter electrode are the deposited MPS layer and the EPD bath. The current de…
