New shape-stabilized phase change materials obtained by single-screw extruder

Shape-stabilized phase change materials (SS-PCM) are promising materials given their potential to control leakage of liquid PCM. However, SS-PCM still has low thermal conductivity and high flammability, which are important properties for several applications, such as the thermal indoor comfort in bu...
