Title:
METHOD OF PREPARING GRAPHENE MICROCAPSULE FIBER
Document Type and Number:
WIPO Patent Application WO/2020/056883
Kind Code:
A1
Abstract:
A method of preparing graphene microcapsule fiber. The spherical microcapsule prepared by the method has a shell, a core structure, and an emulsifier linking the shell and the core structure. The shell structure is composed of a microcapsule wall material, and the core structure is composed of a microcapsule core material. The microcapsule wall material is mainly graphene, the core material is a phase change material, the graphene is modified graphene, and the phase change material is paraffin. A certain amount of graphene is dissolved in water, followed by the addition of an ethanol solution of a silane coupling agent at a pH value of 3-5, stirring, filtering, washing, and drying to obtain the modified graphene. The method of preparing a graphene microcapsule fiber utilizes the characteristics of graphene and paraffin to increase the thermal conductivity coefficient of the microcapsule wall material, such that the paraffin in the microcapsule core material can achieve functions of absorbing heat and controlling heat release, ensuring that body temperature can be controlled to a comfortable perceived temperature.
