Pengaruh Komposisi Al2O3 pada Phase Change Material Berbasis Peg–6000

Abstract

Phase Change Material (PCM) research has been conducted by mixing PEG 6000 - Alumina Oxide (Al2O3) - Sodium Dodecyl Benzene Sulfonate as a Thermal Energy Storage (TES) application. This research is intendent to produce the best PCM with the effect of Al2O3 addition by sonication method. PCMs were characterised to determine their thermal properties (DSC, Thermal conductivity, and TGA) and physical properties (XRD and SEM-EDX). DSC test results show that with the addition of Al2O3, the latent heat enthalpy value decreases but the PCM thermal conductivity test results increase. In addition, in the TGA test, it was found that the working efficiency of the PCM material was up to 282.26℃ in the 88%PEG 6000+8%Al2O3+4%SDBS sample. SEM-EDX results showed that Al2O3 nanoparticles were not evenly distributed in the PEG 6000 structure. XRD results of the 82%PEG 6000+12%Al2O3+4%SDBS sample showed no addition of new phases. Density results obtained PCM composite density value increases along with the addition of Al2O3. In this study, the best PCM sample was obtained with the addition of 88%PEG 6000+8%Al2O3+4%SDBS composition. So that PCM can be applied in building air conditions, textiles, protection in the transportation of temperature-sensitive products, and others.
