Novel Shape-Stabilized Phase Change Material with Cascade Character: Synthesis, Performance and Shaping Evaluation

Thermal Energy Storage (TES) materials, such as Phase Change Materials (PCMs) are proven to enhance the energy efficiency in many fields, automotive and building sectors, which correspond most intensive ones. Shape-stabilized PCM cascade procedures overcome important barriers when PCMs applied since need be encapsulated for their technical use: leakage of liquid phase, corrosion, low heat transfer narrow temperature application. In present study, a novel shape stabilized with performance (cascade phase change material, CSS-PCM) is synthesized via dissolution, allows up 60 wt.% paraffin-PCM final composition. The CSS-PCM based on biopolymer, polycaprolactone (PCL), melting polyester polymeric matrix RT27 Micronal DS 5040 acting PCM. To evaluate new TES materials developed, several techniques have been used: Differential Scanning Calorimetry (DSC), Fourier-Transformed Infrared (FT-IR) spectroscopy were used thermophysical properties chemical different formulations. show an increment storage capacity by increasing content, thermal reliability was also tested: some formulations stable 500 cycles. Finally, potential application polymeric-based 3D, printing attempt performed order analyze viability 3D material first proof concept.
