A series of poly(2-alkyloyloxyethylacrylate) and poly(2-alkyloyloxyethylacrylate-co-methylacrylate) polymers as novel polymeric phase-change materials (PCMs) were synthesized starting from 2-hydroxyethylacrylate and fatty acids. The chemical structure and crystalline morphology of the synthesized copolymers were characterized with Fourier transform infrared and 1H-NMR spectroscopy and polarized optical microscopy, respectively, and their thermal energy storage properties and thermal stability were investigated with differential scanning calorimetry and thermogravimetric analysis, respectively. The thermal conductivities of the PCMs were also measured with a thermal property analyzer. Moreover, thermal cycling testing showed that the copolymers had good thermal reliability and chemical stability after they were subjected to 1000 heating/cooling cycles. The synthesized poly(2-alkyloyloxyethylacrylate) polymers and poly(2-alkyloyloxyethylacrylate-co-methylacrylate) copolymers as novel PCMs have considerable potential for thermal energy storage and temperature-control applications.
