“…The advantages of microPCMs are (1) protecting the PCM against the influences of the outside environment, (2) increasing the heat transfer area, (3) permitting the core material, due to coating, to withstand changes in volume of the PCM, as the phase change occurs, and (4) allowing small and portable energy storage system [12][13][14][15]. Therefore, these features make them more functional than the traditional PCMs in many applications such as functional fibers [16][17][18][19][20] thermal insulation, [21,22] heat transfer, [23,24] solar energy utilization, [25,26] and building materials [27][28][29].…”
