Abstract

Phase change materials (PCMs) have shown great application potential in sustainable energy utilization. The green preparation and efficient application are both focus of PCMs in research. In this paper, without any carbonized process under high temperature, bio-based sodium alginate (SA) and different content of ZrP nanosheets modified by PDA were used to prepare intrinsic framework materials (SA@ZrP) with sensitive lighting absorbance. Polyethylene glycol (PEG)/SA@ZrP with shape stability was fabricated via the vacuum impregnation method. Among them, CPCM5 (SA:PDA@ZrP = 50:50) exhibited excellent thermal storage and cycling stability. Compared with CPCM0 (SA:PDA@ZrP = 100:0), the melting enthalpy (159.8 J/g) and freezing enthalpy (159.3 J/g) of CPCM5 increased 16.8% and 15.4%, respectively. After 100 thermal cycles, there was no significant difference in the latent heat during meting (159.02 J/g) and freezing (157.36 J/g) process. Superior light-thermal performance of CPCM5 also performed during photothermal conversion. Therefore, with the environmentally friendly and low-cost prepared process while excellent thermal properties, PEG/SA@ZrP shows widen application prospects in the photothermal storage and conversion field.

新型生物质杂化气凝胶支撑复合相变材料的开发，提高了光热转换和热能储存能力

相变材料在能源可持续利用方面显示出巨大的应用潜力。绿色制备和高效应用都是PCMs的研究热点。本文采用生物基海藻酸钠(SA)和不同含量的经PDA修饰的ZrP纳米片，在不进行高温碳化的情况下，制备了具有敏感光吸收特性的本征骨架材料(SA@ZrP)。采用真空浸渍法制备了形状稳定的聚乙二醇(PEG)/SA@ZrP。其中，CPCM5 (SA:PDA@ZrP = 50:50)表现出优异的储热性和循环稳定性。与CPCM0 (SA:PDA@ZrP = 100:0)相比，CPCM5的熔化焓(159.8 J/g)和冻结焓(159.3 J/g)分别提高了16.8%和15.4%。100个热循环后，相遇过程的潜热(159.02 J/g)与冻结过程的潜热(157.36 J/g)无显著差异。CPCM5在光热转换过程中也表现出优异的光热性能。因此，PEG/SA@ZrP以其环保、低成本的制备工艺和优异的热性能，在光热存储与转换领域具有广阔的应用前景。图形抽象

期刊介绍： Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field. The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest. Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials. Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
