Investigation and Design of Materials for Energy Applications

Abstract

Thermal regulating microparticles were successfully fabricated, and three classes of polymer were selected, alginate, polyvinyl alcohol, and sheep wool powder, depending on their biosource and non-toxic behavior. In the purpose of ascertaining the morphology efficiency in the preservation of the phase change material, different methodology effectuates, the encapsulation technique through a microfluidic system accomplished to produce mononuclear capsules of Alginate-PCM, in situ polymerization by conventional emulsion executed to produce microspheres alginate/PCM and PVA/PCM, the shape stabilized technique carried out to produce homogenous matrix wool-PVA-alginate/PCM, wool-alginate/PCM. The enhancement of thermal stability by the incorporation of highly stable materials is achieved through the addition of calcium carbonate and calcium silicate inside the alginate polymer, while the titanium dioxide nanoparticles are integrated successfully into the PVA polymer. All the performed samples were investigated for their compatibility, thermal stability, energetic efficiency, and thermal conductivity
