Abstract

The invention discloses a preparation method of a supermolecule gel-based composite phase change material and belongs to the fields of composite materials and composite phase change materials. The preparation method comprises the following steps: preparing a supermolecule gel substrate with a three-dimensional network structure, and regulating the ratio of added raw materials and the three-dimensional network structure of the substrate, so as to well match different types of phase change core materials; dissolving the phase change core materials into water / alcohol to prepare a solution, dispersing the prepared supermolecule gel substrate into the water / alcohol solution of the phase change materials, and drying, so as to obtain the supermolecule gel-based composite phase change material with the shaping superiority. According to the supermolecule gel-based composite phase change material prepared by virtue of the preparation method, the phase change core materials can be effectively immobilized by virtue of a specific network mutual transmission structure of the supermolecule gel substrate, and the leakage problem of the phase change core materials is solved; the developed composite phase change material has relatively good compatibility with the phase change core materials and can be adaptable to different types of the phase change core materials. The preparation method is simple, convenient, feasible, beneficial to large-scale production and wide in application prospect, the process is simple, and conditions are mild.

Description

technical field [0001] The invention belongs to the field of composite phase-change materials, and in particular relates to a preparation method of supramolecular gel-based composite phase-change materials. Background technique [0002] In the context of increasingly scarce energy supply and worsening global climate deterioration, the replacement of traditional energy by new and renewable energy represented by wind energy, solar energy, geothermal energy, and ocean energy has become the only way for sustainable development. However, the distribution of the above-mentioned energy has the characteristics of intermittency, randomness, and volatility. In its energy utilization system, there are mismatches and uneven contradictions between energy supply and demand in terms of time, space, or intensity, resulting in unreasonable and uneven energy utilization. A lot of waste. Energy storage methods mainly include sensible heat, latent heat and chemical reaction heat. Latent heat ...
