Abstract

Comb-like acrylic acid poly(ethylene glycol) methyl ether ester (MPEGA)-co-acrylamide (AM) copolymer [P(MPEGA-co-AM)] as novel phase change materials (PCMs) was successfully synthesized via free-radical water solution polymerization. The structures of P(MPEGA-co-AM) was characterized by Fourier Transform Infrared (FT-IR). The experimental results showed that P(MPEGA-co-AM) copolymer possessed high molecular weight (Mn=66 kg/mol), narrow molecular weight distribution (PDI≈1.14). The phase transition temperature of copolymer decreases to 31 °C, which is very much appreciated and urgently needed for smart PCM related to human body. Moreover, P(MPEGA-co-AM) had good thermal stability even at 380°C.
