摘要:

親水性聚乙烯醇（PVA）具有相對較好的可加工性、安全性及生物可降解性，被廣泛用作支撐材料，可將相變材料封裝在其三維網狀結構中以解決相變組分泄露的問題并使復合材料獲得良好的導熱性。基于此，綜述了分別利用分子間作用力、共價鍵將PVA基體與相變材料復合的物理共混法及化學接枝法，對比了兩種方法用于封裝相變材料的優缺點；總結了目前PVA基相變復合材料的類型、成型方法及性能，包括經濕法紡絲、干法紡絲及靜電紡絲等方法制備的相變復合纖維，經物理共混法制備的相變復合膜以及經一步法原位復合制備的相變復合多孔材料；分析了復合材料中相變組分及成型工藝等對材料結構及相變蓄熱、力學及熱穩定性等性能的影響；同時展望了功能化PVA基相變復合材料的研究方向及發展前景。

Abstract:

Due to the relatively better processability, safety and biodegradability, hydrophilic polyvinyl alcohol (PVA) is widely used as supporting material to encapsulate phase change materials（PCMs） in its three-dimensional network structure, to solve the problem of the leakage of phase change components and make the composites obtain good thermal conductivity. On the basis of that, the methods compounding PCMs with PVA matrix through intermolecular forces of physical blending or covalent bonds of chemical grafting were reviewed. The advantages and disadvantages of both methods for encapsulating PCMs were compared. The types, forming methods and properties of PVA-based phase change composite were summarized. It includes phase change composite fibers prepared by wet spinning, dry spinning and electrostatic spinning, phase change composite films prepared by physical blending, and phase change composite porous materials prepared by one-step in-situ compounding. The effects of phase change components and forming process on the structure, thermal properties, mechanical performance and thermal stability of composites were analyzed. The research direction and development prospect of functional PVA-based phase change composites were also pointed out.
