Talk Title
Some Theoreticals and Primary Characteristics of Microencapsulated Phase Change Materials for Thermal Energy Storage Applications

Talk Abstract

Microencapsulated phase change materials (MEPCM) could be used for energy saving in various applications due to their relatively high and isothermal energy storage capacities. The form of their usage is in general as microparticle additives, slurries, fibers when incorporated to the geometry and fabrics when adhered on the surface. Many different kinds of MEPCMs have been developed on the core and shell basis. The core based researches focused on the application as the shell based ones intended to produce particles for application variety and and ease. MEPCMs have been characterized using common methods like differential scanning calorimetry (DSC), particle size analysis (PSA), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). However MEPCMs can be characterized primarily much easily and some theoreticals enable to do their characterization without some of the proposed sophisticated means. Even the theoreticals may result in better interpretation. For example, density measurements can be used to state the amount of thermal storage property or to find out particle formation type only possible by TEM findings with an extent of errors. In addition, microscopy can state genuine size of the particles instead of SEM. The work is also a starting point for property analysis of composites in other forms for thermal energy storage.

Primary characterization will be a good manual for the researchers for at least to decide if they go on for complete characterization or not. Besides it may be a student laboratory experimentation. Theoreticals could be at least used to make comparison of thermal storage materials properties to theoretically estimated ones. Further they may be used for property estimation and materials design of MEPCMs.

Short Biography

Prof Cemil Alkan is a polymer science and technology expert who has been researching mainly on the synthesis and characterisation of polymeric systems for thermal enegry storage systems since 2004. These systems include polymeric blends and composites, polymeric solid-solid phase change materials and microencapsulation of some PCMs in polymeric shells. Prof Alkan has produced many papers on thermal energy storage materials and he is one of the firsts on the shell structure variations for extended usage of MEPCMs like thermal comforth development in textiles, core varieties of paraffins, fatty acids, etc. and eutectics enabling usage at different temperatres, and characterization.
