摘要：

传统热致相分离法（TIPS）是制备分离膜的重要方法，但操作温度较高，易引起聚合物分解，对设备要求也较高。低温热致相分离法（LT-TIPS）具有操作温度低、膜结构易调控的优点，近年来受到研究者们的关注。本文介绍了LT-TIPS相图特征、单一潜溶剂体系、混合潜溶剂体系、铸膜液中添加剂对膜结构的影响以及LT-TIPS膜应用的研究进展，并分析了LT-TIPS制膜方法面临的挑战和未来发展方向。

Thermally induced phase separation (TIPS) method is an important membrane fabrication method, with problems such as high operating temperature. Low temperature thermal phase separation (LT-TIPS), as an improved TIPS process, has the advantages of low operating temperature and easy adjustment of membrane structure. This review introduces the phase diagram of the low temperature thermally introduced phase separation (LT-TIPS) method, the progress in single solvent system, mixed solvents system and the effects of additives on membrane structure, along with the applications of membranes. The challenges and future development of the LT-TIPS method are provided
