摘要
近年来,尤其以多孔木材为支撑材料制备的相变储能材料已成为生物基储能材料的发展趋势。木材有着序列清晰的多孔隙天然结构,也可通过脱木质素等方法提升其吸附程度,是理想的支撑材料。然而木材孔隙分布不均匀,且大多数木基相变材料为固-液相变材料,存在容易泄漏的缺陷,这也是当前亟待解决的难题。对木基相变材料的原理、结构、制备、应用进行了归纳总结,从封装技术的三个维度阐述了木基相变储能材料的研究进展,并对其发展趋势和未来的重点研究方向进行了展望,以期挖掘木基相变材料更大的潜力,为扩大其应用提供参考。
In recent years,phase change energy storage materials prepared especially with porous wood as the support material have become the trend of biobased energy storage materials.Wood is an ideal support material because it has a well-sequenced porous natural structure,and the degree of adsorption can also be enhanced by methods such as delignification.However,the pore distribution of wood is uneven,and most of the wood-based phase change materials are solid-liquid phase change materials,which have the defect of easy leakage,which is also a problem needs to be solved.In this paper,the structure,principle,application,and preparation of woodbased phase change materials were summarized,the preparation progress of wood-based phase change energy storage materials from the three aspects of packaging technology was introduced,and its development trend and future key research directions was looked forward to in order to tap the greater potential of wood-based phase change materials and provide references for promoting its application.
