Embodiment

[0034] Preparation method of heat conduction enhanced organic phase change energy storage material:

[0035] Step 1, the emulsification process of the organic phase change material, first mix the nanoparticles and the organic phase change material and ultrasonically disperse for 30 minutes to form a uniform dispersion. Then, after mixing the dispersion with emulsifier and solvent evenly, stirring and emulsifying at 40-70°C and 1000-1500 RMP for 2 h to form a stable and uniform emulsion, and obtain an organic phase change material containing nanoparticles;

[0036] Step 2, take a clean and dry beaker, add porous material, and dry in an oven at 110°C for 30 minutes;

[0037] Step 3, mixing the dry porous material obtained in step 1 and the organic phase change material containing nanoparticles obtained in step 2, and ultrasonically dispersing for 10 min, so that the phase change material and the porous material are evenly mixed;

[0038] Step 4, put the mixed sample into a vacu...

Abstract

The invention discloses a heat conduction enhanced organic PCM (phase change material). The heat conduction enhanced organic PCM is prepared from an organic PCM containing nano-particles as a core material and a porous material as a wall material, wherein the nano-particles are boron nitride, CNTs (carbon nano tubes), expanded graphite and graphene oxide. A preparation method of the heat conduction enhanced organic PCM comprises the following steps: 1) a process of emulsifying the organic PCM; 2) a process of adsorbing the organic PCM containing the nano-particles by the porous material undera vacuum condition; and 3) a process of taking out a product obtained after vacuum adsorption. The heat conduction enhanced organic PCM has the advantages that 1) the heat response speed is high, i.e.the heat conduction property is high; 2) the heat accumulation density is high; 3) the heat cycling stability is high; and 4) raw materials are safe, non-toxic and non-corrosive, and the technical characteristics of being simple in preparation process and low in cost are achieved. Therefore, the heat conduction enhanced organic PCM is better in heat conductivity and stability, the using ratio ofenergy sources is improved, and the application prospect is wide.

Description

technical field [0001] The invention relates to the technical field of phase-change materials in the field of organic polymer compound preparation or chemical processing technology, in particular to a heat conduction-enhanced organic phase-change energy storage material and a preparation method thereof. technical background [0002] With the development of economy and the advancement of science and technology, traditional energy is being consumed at an alarming rate, and human beings are facing unprecedented energy shortages. There are two basic ways to solve this problem: one is to develop renewable energy; the other is to improve energy efficiency. Therefore, energy storage is particularly important. Thermal energy storage systems offer possibilities for energy storage, and latent heat storage is the most efficient way to store thermal energy. Phase change material (Phase Change Material, PCM) is a material that uses the heat absorption and heat release characteristics o...
