Fabrication of Phase Change Nanofibers based on Paraffin Wax/ Polyacrylonitrile Blends

ultrafine shape stabilized phase change material (PCM)/nanofiber was prepared via electrospinning process.In this composite nanofiber, Paraffin wax and poly acrylonytrile used as PCM and supporting material respectively. Theeffect of PCM content on the morphology of nanofiber was studied by scanning electron microscope. The SEMobservations indicate various content of PCM could be electrospun into nanofiber. The morphology of compositenanofiber has no obvious variation comparing with PAN nanofiber. The chemical structure of PCM/PAN nanofiber wasanalysed by FTIR. The IR spectrum confirmed appearance of paraffin wax into PAN nanofiber. Differential ScanningCalorimetry (DSC) results showed composite nanofiber have heat capacity. The latent heat of fusion of PCM/PANnanofiber was about 11.85 J/g.
