The polyether amine-based flexible phase change materials with high enthalpy value, preparation method and application thereof, which belongs to the technical field of the polymer phase change materials for energy storage. Phase change materials for heat storage comprise flexible polyether amine-based high molecule network and organic solid-liquid phase change components which is in-situ loaded in the high molecule network. Among them, the flexible polyether amine-based high molecule network has good compatibility with organic phase change components, and the organic phase change molecules are wrapped around polyether amine-based high molecule chains to form crystalline domain with overall flexibility, realizing the organic combination of flexibility and high heat storage capacity. Design and development of the flexible phase change materials with high enthalpy value possess important application value in the flexible wearables and thermal management of electronic components.

Polyether amine-based flexible phase change materials with high enthalpy value, preparation method and application thereof

The present invention relates to the technical field of new materials, and relates to a thermal conduction enhanced organic composite shape-stabilized phase change material and a preparation method thereof. A thermal conduction enhanced organic composite shape-stabilized phase change material, which is composed of a coordination crosslinked network polymer, an organic solid-liquid phase change material and a thermal conduction enhancer, the mass percent are as follows: coordination crosslinked network polymer 1-50%, organic solid-liquid phase change material 40-98.9%, and thermal conduction enhancer 0.1-10%, the coordination crosslinked network polymer being formed by complexing of polymer compound with metal ions. The invention has simple synthesis process and convenient applications, the material having large enthalpy of phase change, excellent shape stabilizing effect, while the phenomenon of liquid leakage will not occur during operation. The material has broad application prospects in the field of thermal energy storage and management.
