A method for preparing and characterizing microencapsulated phase change materials (MPCM) was developed. comparison with a commercial MPCM is also presented. Both contained paraffin wax as PCM acrylic shell. The melting temperature of the around 21 °C, suitable building applications. M-2 (our laboratory made sample) Micronal® DS 5008 X (BASF) samples were characterized using SEM, DSC, nano-indentation technique, Gas Chromatography/Mass spectrometry (GC-MS). presented 6 μm average size...
The discovery of new eutectic phase change materials (PCMs) will overcome the current PCM challenges such as nonbiodegradability, super-cooling, and limited thermal stability. This paper reports on development bio-based PCMs composed binary mixtures fatty acid esters alcohols at their compositions, which provide potential solid-liquid for building applications. Six systems, namely 1-dodecanol (DD) + methyl stearate (MES), DD palmitate (MEP), laurate (MEL), 1-tetradecanol (TD) MES, TD MEP,...
Thermal energy storage offers a viable solution for managing intermediate availability challenges. Phase change materials (PCMs) have been extensively studied their capacity to store thermal when available and release it needed, maintaining narrow temperature range. However, effective utilization of PCMs requires its proper encapsulation in most applications. In this study, microcapsules containing Rubitherm®(RT) 21 PCM (Tpeak = °C, ΔH 140 kJ/kg), which is suitable buildings, were...
Phase-change materials (PCMs) have shown great promise for energy management in buildings and gained attention the field of sustainable energy-efficient construction. However, to fully utilize PCMs, their proper containment is vital. In this study, a photo-induced polymerization process using new thin film UV reactor at room temperature PCM microencapsulation polymer shells different acrylate-based monomers was investigated. Four were investigated: namely, methyl methacrylate (MMA), ethyl...
Thermal energy storage (TES) has been identified by many researchers as one of the cost-effective solutions for not only storing excess or/wasted energy, but also improving systems’ reliability and thermal efficiency. Among TES, phase change materials (PCMs) are gaining more attention due to their ability store a reasonably large quantity heat within small temperature differences. Encapsulation is cornerstone in expanding applicability PCMs. Microencapsulation proven, viable method...
Microencapsulation of phase change materials (PCMs) remain a suitable option within building materials, as they contribute to the thermal mass and provide an energy buffer, added benefit. This paper presents novel method for rapid fabrication microencapsulated at ambient conditions in perfluoroalkoxy (PFA) coiled tube ultraviolet (UV) reactor. The objective this study was optimize key parameters such product yield quality as-prepared microcapsules. Rubitherm® RT-21™ PCM shells...
