The invention discloses a
heat conducting and storing
graphene sizing phase-change material and a preparation method thereof, and relates to the technical field of
heat conducting materials. The heatconducting and storing
graphene sizing phase-change material comprises the following steps that
graphene powder is added into a reactor with deionized water to prepare a graphene solution, the reactoris placed into an
ice water bath, H2SO4 with the
mass concentration being 98%, a
saline solution and
potassium permanganate are added into the reactor, after the certain operation, a proper amount ofhydrogen
peroxide is dropwise added, and a graphene
oxide solution is obtained; dimethyl vinyl
silicone rubber,
heat conducting filler, crosslinking agent,
coupling agent,
platinum catalyst and dispersing agent are added into a vacuum kneading
machine, the graphene
oxide solution is poured into the vacuum kneading
machine to be kneaded,
thermal treatment is performed in the specific environment,and then the graphene
sizing phase-change material is obtained; the heat conducting and storing graphene sizing phase-change material has the natural physical state temperature regulating characteristics and flexibility of various phase-change materials and can be applied in the fields of thermal interface material and
electronic component cooling and heat dissipation, medical apparatuses and instruments, protective clothing and the like.
