Abstract

See full text

Some embodiments of the disclosure provide an ultra-low temperature phase change gel including a phase change matrix, a temperature regulator and a nucleating agent. In some embodiments, the phase change matrix is used as a host material for phase change to store and release cooling capacity, the temperature regulator is used for regulating the phase change temperature of the phase change matrix, and the nucleating agent is used for reducing a supercooling degree of the phase change matrix. The phase change matrix includes a temperature control material and water. The temperature control material includes sodium silicate, dipotassium hydrogen phosphate and aluminum sulfate, and the temperature regulator comprises polyethylene glycol. The nucleating agent includes a composite material formed by free radical polymerization of a reaction monomer and a macroinitiator. The composite material includes polyacrylic acid grafted with silica hybrid nano particles.
