| 摘要 |
The present invention relates to a phase-change composite containing a carbon nanomaterial and a preparing method therefor. The phase-change composite according to the present invention has a structure in which a carbon nanomaterial, of which a surface is functionalized with a surfactant, is adsorbed onto a surface of a core, which is functionalized with a surfactant charged oppositely to the former surfactant, through electrostatic attraction, and thus the phase-change composite is economical since it can be prepared through a simple process; the change in the thermal property of the phase-change material is significantly small; the phase-change composite has excellent shape stability at a high temperature, which is higher than the transition temperature thereof, as well as excellent thermal conductivity, and therefore, the phase-change composite can be favorably used in various fields of thermal storage materials using thermal property controlling materials, electronic device overheat controlling materials, solar heat materials, vehicle parts, building materials, and fibrous materials. |
