Synthesis of Paraffin Wax Phase Change Material Nanoencapsulated by Polyurethane via Interfacial Polymerization

This work deals with the synthesis and physico-chemical characterization of nanoencapsulated paraffin wax with polyurethane (PU) via interfacial polymerization method. In synthesized nanocapsules, the paraffin wax has a function of phase change material, while PU acts as a shell material. The nanoencapsulated PCMs were characterized chemically and morphologically by using Fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM). The results of morphological study showed that the particle size distribution of the nanocapsules were 80–400 nm by digimizer analysis.
