“…In the ELT spectra, some specific absorption areas were observed in the range of approximately 2800-3000 cm − 1 for C-H stretching vibration, and 1350-1500 cm − 1 for CH 2 deformation similar to any previous report [26]. Moreover, the FTIR spectra of paraffin, palmitic acid and myristic acid demonstrate a similarity with the literature [27][28][29]. The peaks at approximately 2950 cm − 1 , 2900 cm − 1 , and 2800 cm − 1 as shown in Figures 3-5 were attributed to the symmetric and asymmetric stretching vibration of -CH 2 and -CH 3 groups of paraffin and fatty acids.…”

The management of end-of-life tires (ELT) waste gains importance in aspect of possible environmental and economic issues so the waste recycling becomes unavoidable. This study describes the fabrication and characterization of a new phase changing material (PCM)/ELT microcomposites that could be used in thermal energy storage. Paraffin together with the 4 fatty acids and ELT rubber powder are used as PCMs and as the supporting material, respectively.Paraffin/ELT composites are fabricated, as well, by the vacuum impregnation method in order to investigate the effect of the preparation method. The thermal, morphological, and chemical properties of the prepared PCM/ELT rubber microcomposites are determined with differential scanning calorimetry (DSC), scanning electron microscopy (SEM), and FTIR, respectively. Additionally, the effects of the PCM amount on the composite materials are investigated. As a result of DSC results, the melting temperature and latent heat of the paraffin/ELT rubber microcomposites are determined as 37.2°C and 80.79 J/g for direct impregnation method and 36.8°C and 80.69 J/g for vacuum impregnation method, respectively. Based on the findings of this study, it can be claimed that PCM/ELT rubber microcomposites can be used as energy-saving materials in thermal energy storage applications.

“…The analysis of phase change behavior of TBB‐LB also showed the same trend and a similar result based on the properties of LB, TD and TBB. Compared with other works, TBC‐LB (113.3 J g −1 ), TBB‐LB (113.6 J g −1 ) exhibited the higher latent heat value than those of microencapsulated 1‐hexadecanol (RTPCMs) (80.7 J g −1 ), composite PCMs with PEG (79.2 J g −1 ), solid‐solid PCM of PU/graphene (90 J g −1 ), binary composite complex fabricated by mixing tetradecanol/myristic acid into the hydroxylpropyl methyl cellulose matrix (102.11 J g −1 ) . To study the cycle and durability of TBC‐LB and TBB‐LB, 100 heating‐cooling cycles were performed.…”

“…For example, paraffin has been used as the PCM to prepare the glazed window, polyethylene glycols with different molecular weight has been discussed on the phase change properties, 3‐hydroxy fatty acids could be used as phase change material . And more, among these organic PCMs, polyhydric alcohols have the advantages of high phase change latent heat, high cycle stability and less severe super‐cooling, which have been used as latent heat energy storage materials, and its lower cost is conducive to its wide industrial application . However, when solid‐liquid transitions occur during the phase change, polyhydric alcohols also exhibit some unfavorable properties especially of liquid leakage, which requires an effective method to solve these problems …”

Shaped-stabilized reversible thermochromic phase change materials of (TBC-LB, TBB-LB) were assembled by impregnation the TBC (crystal violet lactone/ bisphenol A/tetradecanol) or TBB (3,3 0 -Bis (1-n-octyl-2-methylindol-3-yl) phthalide/bisphenol A/tetradecanol) into lignin-retained bamboo (LB) for energy storage. Analysis of the chemical structure of lignin-retained wood showed that the removal of part of lignin from the bamboo contributes to the penetration of the compound, and the partial retention of lignin is advantageous for maintaining high mechanical properties. The SEM micrographs of TBC-LB and TBB-LB indicate that TBC and TBB are well immersed into the porous LB. The TBC-LB showed an endothermic peak at 40.8 C with ΔH m of 113.3 J g −1 and two exothermic peaks at 28.8 C and 21.9 C with ΔH L+S of 110.2 J g −1 , and the value is basically equal to the pure TBC compound, indicating that TBC has been fully immersed in LB to form a composite phase change material. For phase change latent heat and melting-cooling temperature, TBB-LB and TBC-LB showed the same trend. About 100 heating-cooling cycles were performed to evaluate the reliability of TBC-LB and TBB-LB, showing excellent cycle stability. It is foreseen that the prepared shape-stable TBC-LB and TBB-LB have great potential for applying insulation systems in reversible thermochromic phase change energy storage.
