Poly(ethylene glycol) (PEG) modified epoxy phase change polymer with dual properties of thermal storage and vibration damping

Abstract

A novel cross-linked self-sustaining film was prepared by reaction of carboxyl-capped poly(ethylene glycol) (PEG) to epoxy resin, followed by incorporation of the prepared material (named modified epoxy, ME) into epoxy matrix. Self-sustaining films were obtained up to 60 wt% ME in the epoxy matrix. FTIR and 13C NMR were used for chemical characterization of the samples. DSC study exhibited maximum enthalpy for PCM film reaching up to 41 J.g-1. The XRD and POM indicated lesser degree of crystallinity of PEG segments due to constriction by crosslinked epoxy resin. DMA results indicate that the blend of epoxy and ME is compatible up to 30 wt% ME and there is distinct phase separation beyond this composition. The viscoelastic loss or vibration damping characteristics is maximum for 30 wt% blend as indicated by area under loss factor curve.
