Research progress on palmitic acid shape-stabilized composite phase change materials

棕榈酸因存在热导率低和物态相变时易泄漏的缺点,限制了其在诸多领域的发展和应用。棕榈酸定形复合相变材料以支撑材料为基体,将棕榈酸分散在基体材料中,不仅有效解决棕榈酸的泄漏问题,而且基体材料的加入还能提高复合相变材料的热导率。综述了基于不同基体材料的棕榈酸定形复合相变材料的研究进展,指出了棕榈酸定形复合相变材料的不足之处,并展望了其未来研究方向。

The development and application of palmitic acid have been limited in various fields due to its low thermal conductivity and tendency to leak during phase change process.To address these issues,researchers have developed palmitic acid shape-stabilized composite phase change materials using support materials as matrix to disperse palmitic acid within the matrix,effectively solving the leakage problem and improving the thermal conductivity.This article reviewed the current research progress on palmitic acid shape-stabilized composite phase change materials using different matrix materials,summarized their shortcomings,and discussed future research directions.
