A novel fully bio-based Poly (Glycerol-Itaconic acid) (PGI) was designed and highly efficiently synthesized by solvent-free polycondensation. The Poly (ethylene glycol) (PEG) was used as the phase change material (PCM) working substance and encapsulated by the sustainable PGI supporter. PEG chains were tightly encapsulated with the PGI supporting material mainly under hydrogen bonds due to the structural compatibility between PGI and PEG. The PCMs can achieve high form stability and high phase change enthalpies in the same kinds of PCMs. Furthermore, the phase change temperatures and enthalpies of the PCMs can be adjusted conveniently by regulating the PEG content and molecular weight. Notably, this process extremely facilitates the realization of efficient mass production due to the eco-friendly nature, high efficiency and low cost.

全生物基聚(甘油-衣康酸)作为聚乙二醇基形式稳定相变材料的载体

一种新型的全生物基聚(甘油-衣康酸)(PGI)被设计并通过无溶剂缩聚高效合成。聚(乙二醇)(PEG)用作相变材料(PCM)工作物质,并由可持续的 PGI 支持体封装。由于 PGI 和 PEG 之间的结构相容性,PEG 链主要在氢键下被 PGI 支撑材料紧紧包裹。PCMs 可以在同种 PCMs 中实现高形式稳定性和高相变焓。此外,通过调节PEG含量和分子量可以方便地调节相变温度和相变焓。值得注意的是,该工艺具有环保、高效和低成本的特点,极大地促进了高效大规模生产的实现。
