A series of paraffin /poly (methyl methacrylate) blends were prepared as new kinds of form-stable phase change materials by encapsulation of paraffin into PMMA. The blends were prepared at different mass fractions of paraffin. The form-stable paraffin /PMMA blends were characterized using optic microscopy (OM) and Fourier transform infrared (FT-IR) spectroscopy. Thermal characteristics were measured by using thermo gravimetric analysis （TGA） and differential scanning calorimetry (DSC) technique. On the basis of all results, it was concluded that paraffin is encapsulated by PMMA. The blends have good thermal properties and degrade in two distinguishable steps. They have good energy storage capacity and melt at 58-60 °C.The blends have different degrees of hydrophobic. These form-stable paraffin /PMMA blends have important potential for some practical latent heat thermal energy storage applications.

Graphite Composite

The main purpose of this paper was to synthesize a novel form-stable composite phase change material (PCM). Herein, bentonite-based PCMs were synthesized by impregnating Na-bentonite clay with lauric acid (LA) through a vacuum impregnation method. Flake graphite (FG) was used to enhance the thermal conductivity of the composite PCMs. In addition, FG also helped block the leakage of the PCMs. It is worth noting that with the addition of FG, the period of melting and solidifying of composite PCMs were decreased to some extent. Meanwhile, the thermal conductivity of the PCMs has been obviously improved. Moreover, the synthesized composite PCM exhibited a favorable performance of reliability after 200 thermocycling test. Hence, this study showed that the developed composite PCM has the potential to be applied in thermal energy storage systems.

Composite Nanofiber

Phase-change materials have remarkable characteristics due to their simple phase-changeable nature. Within a certain temperature range, these materials can easily change from solid phase to liquid phase or vice versa. It is possible to build thermal energy storage mechanisms, thanks to their latent heat. In this study, composite nanofiber structures were prepared with lauric acid and polyacrylonitrile blends. Nanofiber webs were fabricated via electrospinning technique and combined with phase-change material due to their light weight and high surface area. Thermal energy storage properties were investigated via differential scanning calorimeter, and structural analysis was studied by Fourier transform infrared–attenuated total reflection spectroscopy. Scanning electron microscope was used to investigate the surface morphology of the fibers. Blended polyacrylonitrile–lauric acid nanofibers were successfully converted to nanofiber formation without losing their properties. Results showed that fabricated polyacrylonitrile–lauric acid composite nanofiber webs can be used as a thermal energy storage patch.
