Abstract

Abstract Poly(ethylene glycol) (PEG) polymer is useful as phase change material (PCM) in thermal energy storage systems. In this study, PEG 1000 and clove essential oil (EO) blended with various mass ratios (100/100/25, 150/100/25, 200/100/25) PEG/PLA/EO nanofibers were produced by electrospinning in a poly(lactic acid) (PLA) polymer matrix. The produced nanofibers were characterized by scanning electronic microscopy (SEM), fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC). The fibers were about 370°C and prepared nanofibers have a phase enthalpy of 77.48 Jg-1 at 34.74°C. Nanofibers shows promising potential for use in medical, food safety and textile fields.
