Chapter 23. Designing Organic/Inorganic Colloids by Heterophase Polymerization

摘要

Two inorganic cores, consisting of silica and titania, have been prepared via basic Stoeber synthesis. Those cores have been functionalized, using trimethoxysilyl propylmethacrylate (MPTMS) and introduced into a miniemulsion copolymerization system. The miniemulsion consisted of styrene (S) and 2-hydroxyethyl methacrylate (HEMA), styrene sulfonic acid (SSA) or aminoethyl methacrylate hydrochloride (AEMA) as comonomer in varying compositions. The morphology of the products has been investigated by SEM and dynamic light scattering (DLS) measurements. The composition of the products has been investigated by photoacoustic FTIR (PA-FTIR) spectroscopy and elemental analysis. Thermal properties have been determined by TGA and DSC analysis..
