Abstract

Monodisperse silica nanoparticles were immobilized with poly[3-(N-2-methacryloyloxyethyl-N,N-dimethyl)ammonatopropanesulfonate)] (SiNP-PMAPS) by surface-initiated atom transfer radical polymerization. SiNP-PMAPS was characterized in 1-hexyl-3-methylimidazolium chloride (HMImCl) solution by dynamic light scattering (DLS) and synchrotron small angle X-ray scattering (SAXS) measurements. The relaxation spectrum of DLS and SAXS profile for SiNP-PMAPS solutions showed a unimodal distribution attributed to the homogeneous dispersion of SiNP-PMAPS in the HMImCl without any aggregations. The scattering factor from the SiNP-PMAPS in HMImCl was described by the core-shell model considering interacting excluded-volume chains and assuming Schulz distributed core with the thickness of polymer layer of 56 nm.
