지속 가능한 에너지 저장을 위한 친환경 상변화 물질인 피스타치오 껍질 바이오차

초록

To harness solar energy effectively, it is imperative to utilize eco-friendly and economically viable biochar materials that enhance the heat-retention capacity of phase change materials (PCMs). Contemplating that, the present study explores the use of biochar derived from pistachio shells (PS) to develop sustainable and shape-stabilized energy storage materials. Porous PS biochar (PSB) is obtained through the pyrolytic transformation of PS and is employed to enhance the stability of the phase change material (PCM), dodecanoic acid (DA), maintaining the OA to PS ratios of 2:1 and 3:1. The thermal stabilities and performances of the resulting composites, termed LPB-1 and LPB-2, are evaluated using various techniques including scanning electron microscopy (SEM), Fourier transform infrared spectroscope (FT-IR), differential thermal analyzer (DTA), and thermogravimetric analysis (TGA). These analyses confirm the suitability of the composite PCM for thermal energy storage applications, as it exhibits significant latent heat storage capacity and notable shape stability.
