Abstract: Microencapsulated phase change materials (MPCMs) are excellent materials for the storage of thermal energy, and through their dispersal into a carrier fluid, microencapsulated phase change slurries (MPCS) can be prepared. These slurries exhibit both excellent thermal energy storage and heat transfer properties. A series of MPCS were prepared for this research and subsequently tested using the Hot Disk method for thermal conductivity and specific heat. Other methods of quantification include DSC, TGA, rheometry, and infrared spectroscopy. One of the main properties looked at in this research was the effect of particle concentration on thermal conductivity and viscosity. MPCMs were deemed fit for use in 'passive' applications or in combination with active cooling systems.
