ZrO2/PMMA Nanocomposites: Preparation and Its Dispersion in Polymer Matrix

doi:10.1016/S1004-9541(13)60448-6

Abstract

Abstract: ZrO₂/PMMA nanocomposite particles are synthesized through an in-situ free radical emulsion polymerization based on the silane coupling agent (Z-6030) modified ZrO₂ nanoparticles, and the morphology, size and its distribution of nanocomposite particles are investigated. Scanning electron microscopy (SEM) images demonstrate that the methyl methacrylate (MMA) feeding rate has a significant effect on the particle size and morphology. When the MMA feeding rate decreases from 0.42 ml·min^-1 to 0.08 ml·min^-1, large particles (about 200-550 nm) will not form, and the size distribution become narrow (36-54 nm). The average nanocomposite particles size increases from 34 nm to 55 nm, as the MMA/ZrO₂ nanoparticles mass ratio increased from 4︰1 to 16︰1. Regular spherical ZrO₂/PMMA nanocomposite particles are synthesized when the emulsifier OP-10 concentration is 2 mg·ml^-1. The nanocomposite particles could be mixed with VAc-VeoVa10 polymer matrix just by magnetic stirring to prepare the ZrO₂/PMMA/VAc-VeoVa10 hybrid coatings. SEM and atomic force microscopy (AFM) photos reveal that the distribution of the ZrO₂/PMMA nanocomposite particles in the VAc-VeoVa10 polymer matrix is homogenous and stable. Here, the grafted-PMMA polymer on ZrO₂ nanoparticles plays as a bridge which effectively connects the ZrO₂ nanoparticles and the VAc-VeoVa10 polymer matrix with improved comparability. In consequence, the hybrid coating with good dispersion stability is obtained.
