Embodiment Construction

[0025] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] (1) 0.6g ferrocene Fe(C 5 h 5 ) 2 Dissolve in 30 mL of acetone and sonicate vigorously for 10 min. After sonication, slowly add 3 mL of HO 2 o 2 , stirred vigorously for 30 minutes. The solution was then transferred to a polytetrafluoroethylene-lined stainless steel autoclave with a total capacity of 50 ml and a pressure of 1.2 MPa. The temperature in the kettle was adjusted to 210°C and kept for 24 hours. After the reaction, the solution was cooled to room temperature and treated with ultrasonic dispersion for 15 minutes. The precipitate in the solution was separated by centrifugation with a magnet, and then washed with acetone to obtain a carbon support containing The starting material of ferroferric oxide.

[0027] (2) The magnet collects the initial material and washes it with 1mol / L hydrochloric acid at room temperature to...

Abstract

The invention discloses a hydrate temperature-controlled energy storage magnetic composite material and a preparation method thereof. The hydrate temperature-controlled energy storage magnetic composite material includes a hydrate and a hydrate support, and the hydrate support has two layers. The inner layer is elemental carbon and the outer layer is polymer. The preparation process first uses an autoclave to use ferrocene particles as a template, and wraps the particles with amorphous carbon; then removes the ferric oxide in it with hydrochloric acid, and after removing part, the initial material is soaked in tetrahydrofuran aqueous solution until the material is filled with tetrahydrofuran aqueous solution to prepare base material particles; then monomers, cationic surfactants, and initiators are cross-linked on the surface of base material particles to form a polymer layer to stabilize the material structure and make the final product. The product prepared by the invention has the performance of temperature control and energy storage, can be used periodically, and has a magnetic response function, and can be used for temperature control of electronic equipment and its components with electromagnetic shielding function.

Description

technical field [0001] The invention belongs to the field of energy utilization, and in particular relates to a hydrate temperature-controlled energy-storage magnetic composite material and a preparation method thereof. Background technique [0002] Today, energy and environment are two major issues of human sustainable development. The main fossil energy will cause greenhouse gas emissions, climate change and other issues. Heat energy is an important energy source, which is widely used in production and life, and is also discharged on a large scale. Thermal energy storage can harvest and store waste heat in production and life, effectively solving the problem of time and space difference between thermal energy demand and supply. [0003] Thermal energy storage can be used to store thermochemical energy, sensible heat, latent heat, or a combination of the three. Among them, latent thermal energy storage is a phase change material that achieves higher thermal energy storag...
