Development of composite phase change materials based on n-tetradecane and β-myrcene based foams for cold thermal energy storage applications

• N-tetradecane incorporated composite PCMs were designed for cold thermal energy storage applications. • β -myrcene based porous polymer / nanoclay nanocomposite frameworks were obtained. • Frameworks were prepared by emulsion templating followed by post-polymerization crosslinking. • The incorporation rate of n-tetradecane into the porous frameworks was calculated. • Bio-based form-stable PCMs demonstrated good leak tightness and high thermal stability. β -myrcene based foam / n-tetradecane composite phase change materials (PCMs) were prepared for cold thermal energy storage systems. β -myrcene based foams were synthesized as PCM support material, while n-tetradecane was selected as organic phase change cold storage material due to its appropriate phase change temperature and high heat storage capacity for supplying temperature requirements of the food refrigeration, storage and transportation systems. The polymer foams were prepared in presence of different nanoclay particles by using β -myrcene as bio-based monomer and ethylene glycol dimethacrylate as crosslinker. The form-stable composite PCMs were obtained via impregnation of n-tetradecane into the porous frameworks in one-step. Based on the results, the highest latent heat was measured as 82.14 J/g for form-stable composite PCM, which has framework with higher cavity diameters besides to higher surface area, while the melting and crystallization temperatures determined as 4.37 °C and 1.73 °C.
