GRAPHENE RAMIFICATION-CARBON NANOTUBE COMPOSITE MATERIAL AND PREPARATION METHOD THEREOF

摘要

A graphene ramification-carbon nanotube composite material and preparation method thereof which includes the following steps: step one, adding the graphene ramification and carbon nanotubes to alcohol dispersant and dispersing for 120 - 150 minutes by ultrasonic to form a stable suspension; step two, filtrating the suspension, drying the solid substance and cooling it to room temperature to obtain the graphene ramification-carbon nanotube composite material. In the composite material produced by the method, the graphene ramification and carbon nanotube composite form an intermixing and interveining structure to avoid the aggregation and stacking of the graphene ramification, so as to enable complementarities in structure and function of the graphene ramification and carbon nanotubes and improve the conductive property of the composite material.
