[0030] The invention provides a composite hydrogel for heat management on the surface of a heat source and reuse of waste heat. The composite hydrogel with simultaneous evaporation and heat dissipation and waste heat recovery refers to polyacrylamide hydrogel with a certain concentration of hygroscopic salt and Materials composed of solutions of chemical thermoelectric materials. The hygroscopic salt is lithium bromide, lithium chloride, calcium chloride, etc., with a molar concentration of 0-17.3mol / L. The chemical thermoelectric material is potassium ferricyanide / potassium ferrocyanide or potassium ferricyanide / ammonium ferrocyanide, etc., with a molar concentration of 0-0.4mol / L. The surface of the composite hydrogel with simultaneous evaporative heat dissipation and waste heat recovery capability is smooth and smooth, and can directly cover the surface of a heat source. The concentration of the mixed solution composed of hygroscopic salts and chemical thermoelectric mater...
Embodiment 1
[0038] Provided in this example, the specific preparation method of the composite hydrogel with simultaneous evaporation and heat dissipation and waste heat recovery capabilities is as follows:
[0039] Step 1, 2M acrylamide as monomer, 0.001M N,N'-dimethylbisacrylamide as crosslinking agent, 0.002M 2-hydroxy-4'-(2-hydroxyethoxy)-2-methylbenzene Acetone was used to prepare a mixed solution for the UV initiator.
[0040] Step 2. Pour the solution obtained in step 1 into 10×5×3.6cm 3 in the mold.
[0041] Step 3, using a UV lamp to cure for 8 hours under a nitrogen atmosphere to obtain a polyacrylamide hydrogel.
[0042] Step 4. Take out the polyacrylamide hydrogel from the mold, and place it on a heating platform at 60° C. until it is completely dry.
[0043] Step 5. Submerge the dried polyacrylamide hydrogel in a mixed solution of potassium ferricyanide / potassium ferrocyanide (0.1M) and lithium bromide (9.4M) until it swells completely.
[0044] Step 6. Take out the gel, w...
