| Abstract |
Shape-stabilized phase change materials (SSPCMs) with low cost, superior thermal stability, and shape stability are necessary, and these materials are getting more interest in thermal energy storage (TES) applications. In this study, a new micro and meso porous activated carbon (PAC) has been developed from leather industry solid waste. The prepared PAC showed a high surface area of 1209.1 m(2) g(-1) with an average pore size of 3-4 nm. Further, a shape-stabilized phase change material composite, consisting of n-eicosane as a PCM and PAC as a supportive material has been prepared using simple blending and impregnation methods with different mass fractions (1:0.5, 1:0.75, 1:1, 1:1.25) of PAC/n-eicosane. The PAC/n-eicosane-ratio of 1:1 shows good chemical stability and thermal reliability even after 100 cycles of melting and crystallization. The prepared PAC/n-eicosane 1:1 also exhibits a good thermal conductivity of 0.54 Wm(-1) k(-1) Differential scanning calorimetry (DSC) analysis indicated that the PAC/n-eicosane 1:1 melted at 37.7 degrees C with a latent heat of 98.1 J/ g and solidified at 33.5 degrees C with a latent heat of 96.3 J/ g. Further, we fabricated smart leather (15 x 15 cm(2)) using this for real-time industrial-scale application. The PAC/n-eicosane1:1 coated leather (smart leather) exhibited a temperature difference of 2.9 +/- 0.1 degrees C, lower than control leather, thus resulting in cooler leather. Thus, this work provides an economical, eco-friendly, and efficient method for thermal energy storage. This work also addresses the circular economy principle where the waste from the leather industry has been converted into a value-added product and reused for making smart leather. |
