This research works involves the production of microencapsulated phase change material (PCM) in which paraffin wax was used as core components with sebacoyl chloride (SC) and hexamethylene diamine (HMD) to make polyamide as a shell component. The microencapsulated PCM was characterized using Fourier Transform Infrared (FTIR) and Scanning Electron Microscopy (SEM). Thermal energy storage capacity was measured by Differential Scanning Calorimetry (DSC) while thermal conductivity was measured by Thermal Gravimetric Analysis (TGA). The microencapsulated PCM were found to have a regular spherical shape with a size of 50 μm while FT-IR indicated that the microencapsulation process occurs due to the existence of alkyl group (C-H) and carbonyl group (C=O) in the spectra. DSC analysis shows that the paraffin start to melt at 47°C to 56°C with thermal energy storage capacity 140.097 J/g and 114.766 J/g for sample A and sample B respectively. Thermal conductivity of PCM related with its thermal energy storage.
