Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
A preparation method of a composite phase-change material comprises the following steps:
the method comprises the following steps: dissolving polydopamine in a phosphoric acid buffer solution at room temperature, stirring, performing suction filtration after reaction is completed to obtain a dark precipitate, and drying the dark precipitate to obtain black powdery polydopamine nanoparticles;
this step may be specifically performed as follows: dissolving 0.25-0.5 g of polydopamine in 50-200 mL of phosphoric acid buffer solution as a reaction medium with the pH value of 8.5 in an open container, continuously stirring at the rotating speed of 500-700 rpm, reacting at room temperature (25 ℃) for 12-24 h, performing suction filtration, and drying the obtained dark precipitate (the drying temperature is 45-75 ℃ and the drying time is 12-24 h) to obtain black powdery polydopamine nanoparticles, wherein the preparation method of the phosphoric acid buffer solution comprises the following steps: sodium dihydrogen phosphate and disodium hydrogen phosphate were dissolved in water to prepare a phosphate buffer solution having a pH of 8.5.
Step two: dissolving polyethylene glycol in absolute ethyl alcohol, adding the polydopamine nano-particles after the polyethylene glycol is completely dissolved to form a suspension, carrying out vacuum impregnation on the suspension, stirring, drying, and completely evaporating ethanol to obtain the composite phase change material taking the polyethylene glycol as a core material and the polydopamine nano-particles as carriers.
This step may be specifically performed as follows: preparing a novel composite shape-stabilized phase change material by taking polyethylene glycol as a core material and polydopamine nano-particles as a carrier: dissolving 0.1-0.3 g of polyethylene glycol in 10-15 mL of absolute ethanol, adding 0.05-0.1 g of polydopamine nanoparticles after the polyethylene glycol and the polydopamine are completely dissolved, wherein the mass ratio of the polyethylene glycol to the polyethylene glycol and the polydopamine is 0.45-0.85, carrying out vacuum impregnation operation on suspension formed by the polyethylene glycol and the polydopamine for 1-2 h, stirring the suspension at the temperature of 45 ℃ for 4-8 h at the rotating speed of 500-700 rpm, drying the mixture in a constant-temperature drying oven at the temperature of 45 ℃ for 12-24 h after the suspension is finished, completely evaporating the ethanol, and finally obtaining a solid product, namely the composite phase change material.
The performance of the composite phase change material prepared by the above method is shown in fig. 1 to 7:
as can be seen from fig. 1, 2, 3 and 4, PEG was successfully complexed with the polydopamine carrier PDA.
As can be seen in fig. 5, pure PEG showed two strong diffraction peaks at 19.08 ° and 23.19 °, indicating the highly crystalline structure of the pure PEG material. The diffraction peak positions of the PEG/PDA material of the phase-change composite material are basically the same as those of the pure PEG material, and the peak values are respectively positioned at 19.06 degrees and 23.28 degrees, which shows that the introduction of the mesoporous material does not influence the crystal structure of the PEG, namely the crystallinity of the PEG.
As can be seen from FIG. 6, pure PEG showed an endothermic melting peak at 63.31 ℃ with a melting enthalpy of 195.36J/g, and an exothermic crystallization peak at 35.03 ℃ with a solidification enthalpy of 175.86J/g. Comparative example phase change composite PEG/PDA showed an endothermic melting peak at 63.49 deg.C with a melting enthalpy of 105.12J/g, an exothermic crystallization peak at 32.44 deg.C with a solidification enthalpy of 90.24J/g. Therefore, the phase change composite material PEG/PDA has a higher enthalpy value, which shows that the PEG is fixed by using polydopamine as a carrier to prepare the shape-stabilized phase change material, so that the PEG can be prevented from leaking in the phase change process, and the heat storage performance of the PEG cannot be influenced.
As can be seen from fig. 7, comparing the curve corresponding to the phase change composite PEG/PDA with the curve corresponding to the polydopamine carrier PDA, the curve corresponding to pure PEG, no significant new peak is observed in the curves, which indicates that the interaction between PEG and polydopamine PDA is physical and that the interaction can prevent the phase change composite from leaking out during the phase change process.
