Preparation of Novel Core‐Shell Nanocomposite Particles by Controlled Polymer Bridging

Abstract: Ceramics that are composed of nanosized granules show enhanced properties in various applications. A layer-bylayer deposition process is developed in this study to prepare core-shell nanocomposite particles, using controlled polymer adsorption. Submicrometer-sized alumina particles that have been chosen as the starting core particles are first dispersed by pH control and then modified by adsorption of anionic poly(acrylic acid) to facilitate the subsequent deposition of nanoparticles on them. A key step in the… Show more

“…The prepared core‐shell structured particles are finally calcined to produce CMS phosphors by a reaction between the shells (mixed hydroxides) and the cores (SiO 2 ). Such processes using polycations or polyanions for preparing core‐shell particles have recently been well exploited 9–11 . The distinct feature of the present method is that spherical SiO 2 particles with a narrow size distribution are used both as the morphology‐determining template and as the precursor.…”

“…It is rarely found in nature because of its high temperature and low-pressure formation conditions [1]. The occurrence of mullite is a result of post-caledonian volcanic activities in which high temperature mullite phases are deposited when clay minerals are heated through contact with magma [2].…”
