The microencapsulation of PCMs involves enclosing them in thin and resilient polymer shells so that the physical state of this material can be changed from solid to liquid and back again within the shells. The utilization of microencapsulated PCMs in textile goods is advantageous since the encapsulation prevents PCM dispersion in the structure, reduces evaporation and reaction of PCMs with the outside environment, provides an increased heat-transfer area and a constant volume, and allows an easy application without affecting other textile properties and a normal fabric-care. In this paper the structural composition, preparation methods and characteristics of the microcapsules are discussed. Microencapsulation is a very time-consuming and complicated chemical process, running over several stages, making the microPCMs very expensive. In addition to microencapsulation of PCMs numerous attempts have been made to contain organic PCMs in certain macrostructures such as polymer matrices or porous materials (silica powder, perlite, expanded graphite). These containment structures are known as form-stable composite PCMs. The preparation and characterization of novel form-stable phase change material (PCM) is presented.
