Beschreibung
Zusammenfassung:	The invention discloses a flexible composite phase change membrane and a preparation method and application thereof, the preparation method comprises the following steps: S1, dissolving polyacrylonitrile and polystyrene in an organic solvent to obtain an electrostatic spinning solution, and carrying out electrostatic spinning by adopting the electrostatic spinning solution to obtain a nanofiber membrane; s2, dipping the nanofiber membrane in the S1 into a solvent containing soluble metal salt and an organic carboxylic acid ligand, and drying to obtain a nanofiber membrane loaded with an MOF material; s3, carrying out annealing treatment on the nanofiber membrane loaded with the MOF material to obtain a carbon nanofiber membrane; and S4, performing vacuum impregnation on the carbon nanofiber membrane in the phase change material, and drying to obtain the flexible composite phase change membrane. The preparation method provided by the invention is simple and suitable for large-scale production, the prepared fle
