| description | Salt hydrates are latent storage materials with exterior properies like energy storage density, availability and cost efficiency. However many of them have handicaps not overcome yet like irreversibility, corrosion and overcooling. In this work, it is aimed to produce polymeric based salt hydrates for the first time. For this reason some selected polymers (polyvinyl alcohol (PVA), poly(ethylene-co-acrylic acid) (PEAA) and polystyrene (PS) have been functionalized through chemical processes to impart salt clusters in the matrix consisting of some water together. For sulfonation and sodium neutralization, known procedures at molecular basis have been used, as for the characterization, FTIR was exploited. Thermal characteristics; phase change temperature, enthalpies, specific heat values, phase change reversibility and total enthalpy have been determined using differential scanning calorimeter (DSC) technique. Furthermore, surface characteristic through contact angle measurements are considered as remarkable to monitor the change in the nature (hydrophobicity) of the polymeric system. |
