Abstract

Phase change material-polystyrene (PCM-PSt) nanocapsules were prepared via a modified resin-fortified miniemulsion (RFME) polymerization process using an alkali soluble resin (ASR). Poly(styrene-co-acrylic acid) (SAA), which is a functional amphiphilic polymer, was used as the surfactant for the resin-fortified emulsion polymerization. A co-surfactant and a crosslinker were adopted to improve the PCM encapsulation efficiency. The average particle size and heat capacity of the optimized PCM-PSt nanocapsules were about ∼280 nm as measured by dynamic light scattering (DLS) and ∼110 J/g as measured by differential scanning calorimetry (DSC), respectively. The morphology and the inner structure of the nanocapsules were investigated using scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The synthesized nanocapsules showed good adhesive and thermal storage properties, and were amenable for processing by dip-coating methods. [Figure not available: see fulltext.]
