Versatile natural dispersants for electrophoretic deposition of materials

Natural anionic molecules, such as glycyrrhizic acid and 18β-Glycyrrhetinic acid are used as dispersants for electrophoretic deposition (EPD) of polyvinylidene fluoride, polytetrafluoroethylene, diamond and composites. The superior behavior of the dispersants is linked to the beneficial effects of their chemical structure, pH-dependent charge, pH-dependent solubility, and film-forming properties. The analysis of the deposition yield provides an …
