Description

technical field [0001] The invention belongs to the field of composite material manufacturing, and in particular relates to a helical carbon nanotube hybrid graphene composite plastic and a preparation method thereof. Background technique [0002] Graphene is a new carbonaceous material in which carbon atoms are tightly packed into a single-layer two-dimensional honeycomb lattice structure. The carbon atomic structure of fully conjugated sheet arrangement endows graphene with excellent properties. The strength of graphene is the highest among the tested materials, reaching 130Gpa, more than 100 times that of steel, and has very high electrical conductivity and thermal conductivity, reaching 6000S / cm and 5300W / m respectively 2 / K therefore has broad application prospects. [0003] In helical carbon nanotubes, not only carbon atoms assemble to form a tubular structure, but also the formed tubular structure presents a mesoscopic-sized helical morphology. In terms of microsco...
