Occlusion of Sulfate-Based Diblock Copolymer Nanoparticles within Calcite: Effect of Varying the Surface Density of Anionic Stabilizer Chains

摘要: Polymerization-induced self-assembly (PISA) offers a highly versatile and efficient route to wide range of organic nanoparticles. In this article, we demonstrate for the first time that poly(ammonium 2-sulfatoethyl methacrylate)-poly(benzyl methacrylate) [PSEM–PBzMA] diblock copolymer nanoparticles can be prepared with either high or low PSEM stabilizer surface density using RAFT dispersion polymerization in 2:1 v/v ethanol/water mixture aqueous emulsion polymerization, respectively. We then use these model gain new insight into key topic materials chemistry: occlusion additives inorganic crystals. Substantial differences are observed extent two types anionic calcite (CaCO3), which serves as suitable host crystal. A leads uniform nanoparticle within at up 7.5% w/w (16% v/v), while minimal occurs when nanoparti...
