Recently, polymeric dispersants have been extensively used in various fields such as paints, inks, CNTs, displays, etc. The chemical structure of polymeric dispersants for pigment has an important role to improve dispersion stability and prevent aggregation or flocculation of pigment in organic or aqueous solvent system. Polymeric dispersants should contain both anchoring group that interact with pigment surface and stabilizing group that provide entropic stabilization. In this study, we investigate the interaction between different polymeric dispersants and pigment blue. For the purpose, we synthesized well-defined various block copolymers containing prenominate two groups with different molecular weight and composition by atom transfer radical polymerization (ATRP). The synthesized block copolymers were characterized by gel permeation chromatography (GPC) and NMR spectroscopy. |
