Abstract

In this paper, surface-initiated atom transfer radical polymerization (SI-ATRP) on surface of Pickering stabilizer for microencapsulation was investigated. By SI-ATRP on initiator-immobilized SiO₂ particles, emulsion droplets were involved into microcapsules. The density of PMMA chains on SiO₂ surface reached 1.31chainnm^-2 and the initiator efficiency was estimated to be 28%. The results confirmed that polymerization was confined successfully at the interface of emulsion and 80% of polymer chains were formed via SI-ATRP on Pickering stabilizer. This covalent between SiO₂ and polymer endowed the prepared microcapsules with good durability and thermal reliability in phase change materials application.
