Use of phase change materials to develop electrospun coatings ofn interest in food packaging applications

摘要

In the present study, a heat management PS foam tray containing an ultrathin fiber-structured PS/PCM coating was prepared by using high throughput electrohydrodynamic processing. To this end, polystyrene (PS) was used as the encapsulating matrix of a commercial phase change material (PCM) called RT5 (a blend of paraffins with a transition temperature at 5 degrees C), by using the electrospinning technique. With the aim of imparting heat management capacity to the trays, the PS tray was coated by
