摘要

固-固相变复合材料往往存在热焓值低和导热性差的问题，严重制约了其在电池热管理和建筑节能等领域的应用。本研究将聚乙二醇（PEG）和醋酸纤维素（CA）溶于十八烷（ODA）中，利用异佛尔酮二异氰酸酯（IPDI）引发二者接枝聚合反应，使封装材料合成和相变材料定形过程实现同步进行，一步法制备出醋酸纤维素-聚乙二醇-十八烷（CA-PEG-ODA）复合相变材料。结果表明，CA-PEG-ODA展现出优异的形态稳定性，热焓值最高达111.10 J/g，100次循环后仍具有104 J/g的热焓值，循环耐久性能优异。氮化铝的加入提高了CA-PEG-ODA的导热能力，导热系数达0.496 W/(m·K)，较CA-PEG-ODA提升了96.8%。在电池热管理测试中，复合相变材料可有效降低电池在放电过程中的温度，最高降温达3 ℃。本研究提出的基于固-固相变材料的内部聚合封装法，为定形相变材料的高效规模化生产提供了新的思路。

Abstract

Solid-solid phase change composites are typically plagued by low enthalpy and poor thermal conductivity

which severely impede their applications in fields such as battery thermal management and building energy con-servation. In this study

polyethylene glycol (PEG) and cellulose acetate (CA) were dissolved in octadecane (ODA)

and isophorone diisocyanate (IPDI) was employed to initiate the graft polymerization reaction between PEG and CA. This innovative approach enabled the synchronous realization of encapsulant synthesis and phase change material shaping

thus fabricating cellulose acetate-polyethylene glycol-octadecane (CA-PEG-ODA) composite phase change materials via a one-step method. The results demonstrate that the CA-PEG-ODA com-posites exhibit excellent morphological stability

with a maximum latent heat enthalpy of 111.10 J/g. Notably

the enthalpy remains as high as 104 J/g even after 100 thermal cycles. The incorporation of aluminum nitride (AlN) significantly enhances the thermal conductivity of CA-PEG-ODA

reaching 0.496 W/(m·K)

which repre-sents a remarkable increase of 96.8% compared with the pristine CA-PEG-ODA. In the battery thermal man-agement tests

the composite phase change materials effectively reduce the temperature of batteries during the discharge process

achieving a maximum temperature drop of 3 °C. The internal polymerization encapsulation strategy based on solid-solid phase change materials proposed in this work provides a novel insight for the effi-cient and large-scale production of shape-stabilized phase change materials.
