Pengaruh Komposisi Fe3O4 pada Phase Change Material (PCM) Berbasis Peg 6000-Getah Damar

Abstract

Phase change material (PCM) compositions based on PEG 6000, Fe3O4, resin, and SDBS by sonication method at 80 ° C frequency 40 kHz was prepared. The composition variations of the mass used are 2%Damar : 98%PEG6000, 2%Fe3O4 : 1%SDBS : 2%Damar : 95%PEG6000, 4% Fe3O4 : 2%SDBS : 2%Damar : 92% PEG6000, dan 6%Fe3O4 : 3%SDBS : 2%Damar : 89%PEG6000. This research was conducted to determine the effect of composition variation F3O4 , the thermal and physical characteristics of PCM, and to determine the optimum composition of PCM. DSC thermal characterization results Fe3O4 with the addition of having the greatest enthalpy value of 205.25 J/g. Thermal conductivity characterization results have the highest conductivity in 0.36 W/mK. And the results of TGA characteristics started to be degraded at a temperature of 189.16C and a mass loss of 94.36%. The physical characterization results of PCM with XRD analysis, the pattern of the graph shows a tetragonal crystal structure on PEG 6000-resin and for the addition Fe3O4 has a cubic crystal structure. The results of density testing increased with the addition of Fe3O4 . The most optimum composition concentration based on thermal distribution analysis is in the composition of PCM 2%Fe3O4 : 1%SDBS : 2%Damar : 95%PEG6000.
