Embodiment 1
[0038] See attached figure 1 A schematic diagram of the manufacturing method of the flexible renewable dehumidification composite material, the method includes the following steps:
[0039] S1. Mix thermoplastic polyurethane and conductive carbon black at a mass ratio of 1:1, use NMP as a solvent, mix and mix to form a flexible thermoelectric slurry with a mass fraction of 25%, and put the slurry into an electrospinning machine 1 for spinning Formed, then cooled by cooling water 2, and then sent into an 80°C blast drying oven 4 under the traction of auxiliary rollers 3 to obtain a flexible thermoelectric substrate 81, as shown in the attached figure 2 shown;
[0040] S2. Mix PDMS and NMP solution uniformly to form an insulating polymer slurry with a mass fraction of 45%, and the flexible thermoelectric substrate 81 passes through the insulating polymer slurry 5 and the 80° C. blast drying oven 4 in sequence to obtain an insulating layer 82. as attached image 3 shown;
