PHASE-TRANSITIONAL MATERIAL, METHOD OF MANUFACTURING THEREOF AND METHOD OF MANUFACTURING MODULE WITH PHASE-TRANSITIONAL MATERIAL

A phase-transitional material, a method of manufacturing thereof, and a method of manufacturing a module with the phase-transitional material are disclosed. A phase-transitional material which contains a metal to form a coordinate bond and a solvent to dissolve the metal, a method of manufacturing the phase-transitional material, including removing oxygen and moisture in air by placing a metal under a vacuum condition (S1 step), preparing the metal as a powder or lamina, introducing the metal into a container having an open face under an inert gas atmosphere, and fastening a connection unit allowing a solvent to be introduced into the face and a vacuum state to be created (S2 step), achieving a temperature equilibrium by maintaining an ambient temperature at a boiling or freezing point of the solvent after maintaining the vacuum state for a predetermined time using the connection unit, and introducing the solvent through the connection unit (S3 step), preparing a solution by mixing the metal with the solvent in the container homogenously (S4 step), and storing the container at −10 to 10° C. to allow the solution to expand and flow out through the connection unit (S5 step), and a method of manufacturing a module with the phase-transitional material may produce highly-efficient electric energy by converting energy lost as heat into electric energy. Furthermore, a phase-transitional material with which heat may be effectively emitted from electronic equipment devices such as computers and a module with the phase-transitional material may be provided.
