제목 Preparation and characterization of Phase change material nano-sized capsules via Modified Resin Fortified Miniemulsion Polymerization
초록 Phase change material-polystyrene (PCM-PS) nano-sized capsules were prepared by modified resin fortified miniemulsion (RFME) polymerization using the alkali soluble resin (ASR). poly(styrene-co-acrylic acid) (SAA) , which is functional amphiphilic polymer, was used as the surfactant of resin fortified emulsion polymerization. Co-surfactant and crosslinker were improved the PCM encapsulation efficiency. Average particle size of nano-sized capsules was about 300nm by DLS. Morphology and inner structure of nano-sized capsules were proved by SEM and TEM method. Particle size distribution, heat storage and thermal stability of nano-sized capsules were analyzed by differential scanning calorimetry and thermogravimetry analysis.
