Dispersion of industrial blue pigment in organic medium using carboxylic dispersant additives |
초록 |
The dispersion of the organic phthalocyanine blue pigment (β-Copper phthalocyanine(β-CuPc)) in organic solvent requires the use of dispersant additives. Carboxylic dispersants was investigated regarding this propose. Dispersion stability of the pigment evaluated by means of Turbiscan as a stability measurement and intensity of UV/vis spectroscopy. As the type of the blue pigment and organic solvent was changed, stability of dispersion increased or decreased. Dispersant adsorbs at the surface of pigment while taking a flat conformation with tail and possibly few loops which contributes to the steric stabilization. The consequences of the deflocculation of the suspension are improved stability of the pigment. |
