低共熔溶剂在储能与传热方面的研究进展

低共熔溶剂（deep eutectic solvents，DESs）通常是由一定化学计量比的氢键受体和氢键给体以氢键缔合的形式组成。因其具有低成本、无毒、饱和蒸气压低、热稳定性好、导电性好等优点，现已在有机合成、材料化学、电化学、生物质降解、催化等多个领域得到广泛应用。近年来，随着现代社会对高效能量存储和换热方面需求不断增加，低共熔溶剂在储能与传热等领域的应用受到研究人员的广泛关注。从“储与传”的角度详细综述了近年来低共熔溶剂在储能与传热方面的研究进展，从不同能量传递形式的角度出发主要分为以下两个部分：作为低共熔相变储能材料满足对潜热、相变温度及稳定性等方面的要求；作为传热工质满足对高效传热的需求。

Recent advances of deep eutectic solvents in energy storage and heat transfer

Deep eutectic solvents (DESs) are new type of ionic liquid alternatives, usually composed of a certain stoichiometric ratio of hydrogen bond acceptors and hydrogen bond donors via hydrogen bonding association. Because of its low cost, non-toxicity, good thermal stability, low saturated vapor pressure and electrical conductivity, it has been widely used in many fields such as organic synthesis, material chemistry, electrochemistry, biomass degradation, catalysis and so on. In recent years, with the increasing demand for efficient energy storage and heat transfer in modern society, the application of low eutectic solvents in the fields of energy storage and heat transfer has attracted extensive attention from researchers. In this paper, the research progress on energy storage and heat transfer of low eutectic solvents in recent years is reviewed in detail from the perspective of “storage and transfer”. It is mainly divided into the following two parts from the perspective of different energy transfer forms: as a phase change energy storage material to meet the requirements for latent heat, phase change temperature and thermal stability, and as a highly efficient heat transfer working fluid to meets the demand for effective heat transfer.
