MK, 317W/mK and 237W/mK.Excellent heat conduction and mechanical property makes graphene in the great development potentiality of field of heat management, but this
A little performances are all based on microcosmic nanoscale, to form the application also bigger difficulty of macroscopic view.Therefore, by microcosmic graphite
Alkene assembles the material to form macroscopic view, while it will be that graphene scale application is used for heat management to keep or keep its nano effect substantially
The important channel in field.
