Well-Defined 4-Arm Star Polymeric Dispersants for Copper Phthalocyanine by ATRP |
| 초록 |
Polymeric dispersants have been applied to academic research and various fields of industry, such as paints, inks, CNTs, displays, cosmetics, etc. The chemical structure of polymeric dispersants for pigment is important 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 describe the synthesis of 4-arm star polymeric dispersants which containing quaternized (2-dimethylamino)ethyl methacrylate (DMAEMA) and benzyl methacrylate (BzMA) as anchoring group and oligo(ethylene oxide)methyl ether methacrylate (OEOMA) as a stabilizing group by atom transfer radical polymerization (ATRP). The resulted star polymer was characterized by GPC and 1H NMR. We studied dispersibility and dispersion stability by DLS and turbiscan. |
