Embodiment 1

[0016] Take butadiene rubber as an example. Graphene, carbon nanotubes and butadiene rubber were mixed in an internal mixer for 10 minutes according to the weight ratio of 1:9:100, and the obtained composite material was vulcanized at 160° C. for 10 minutes to obtain a graphene / carbon nanotube / butadiene rubber composite Material. The volume resistivity of the material is 7×10 6 Ω·cm, the tensile strength is 3MPa, and the tear strength is 18KN / m.

Embodiment 2

[0018] Take silicone rubber as an example. Silicone rubber 100g is dissolved in 500ml of tetrahydrofuran (THF), graphene and carbon nanotubes are dispersed in 100ml THF by ultrasonic according to the weight ratio of graphene and carbon nanotubes, and the total weight of 3g is then mixed evenly in the air and Excess THF was removed in a vacuum oven. The obtained composite material was vulcanized at 160° C. for 10 minutes to obtain a graphene / carbon nanotube / silicone rubber composite material. The volume resistivity of the material is 4.9×10 9 Ω·cm, the tensile strength is 1MPa.

Description

technical field [0001] The invention relates to a conductive graphene carbon nanotube hybrid polymer composite material and a manufacturing method thereof. The graphene carbon nanotube hybrid polymer composite material can be used as an antistatic and electromagnetic shielding material to be made into a conductive carpet , packaging of electronic products, components of mobile phones, antistatic tread rubber for tires, and electromagnetic shielding coatings for aerospace equipment, etc. Background technique [0002] Since the discovery of carbon nanotubes by Iijima in 1991 and the first preparation of graphene by Andre Geim and Kostya Novoselov in 2004, these two carbon nanomaterials have received extensive attention, because both of them have very outstanding physical properties and are expected to pass Polymer modification to give polymers better properties. However, there have been two important problems in the application of carbon nanotubes that have not been resolved....
