Thermal Analysis of Organic and Nanoencapsulated Electrospun Phase Change Materials

Latent heat stored in phase change materials (PCM) can greatly improve energy efficiency indoor heating/cooling applications. This study presents the and methods for formation characterization of a PCM layer latent thermal storage (LHTES) application. Four commercially available PCMs comprising classes organic paraffins non-paraffins were selected Pure water emulsions experimentally investigated. electrospun microfibers produced by co-axial electrospinning technique, where solutions Polycaprolactone (PCL) 9% w/v 12% dichloromethane (DCM) used as fiber shell materials. emulsified with sodium dodecyl sulfate (SDS), Polyvinylalcohol 10% (PVA) constituted core fibers. The behavior PCM, emulsions, fibers analyzed differential scanning calorimetry (DSC). A commercial paraffin temperature 18 °C (RT 18) its pure forms was found to be suitable candidate LHTES. PVA-PCM matrix RT18 PCL concentration showed most promising results leading an encapsulation 67%.
