Abstract

In this paper, we prepared mono-component magnetic toner by suspension polymerization method. Detailed investigation focused on the particle size distribution and morphology of final product. Theoretical research and experimental result show that particle size distribution (PSD) of polymerized toner is mainly controlled by surfactants and inorganic stabilizer. Deliberated selected surfactants can decrease the surface tension significantly and without emulsion formation. Added fine inorganic magnetic pigment forms a strong film, which prohibited the coagulation of dispersed monomer's droplet. After carefully selection of operation conditions, final polymerized toner with average diameter of around 10 microns and span of 1.5 to 2.0 can be acquired. The added hydrophilic fine pigment particles have a strong tendency to enrich on the interface which can be can be seen clearly from SEM and TEM photo of the polymerized toner. Theoretical analysis indicates that surface modification of magnetic particles can increase the affinity between monomer and pigments, so to minimize surface accumulation. Related experiment results showed that selected silane coupling agent and titanate coupling agent are not as so effectively as expected. In the end, mono-component magnetic toner with spherical shape and rough surface was obtained by suspension polymerization method.
