Abstract

The invention discloses a method used for extracting a carbene material from plant. The method comprises following steps: a, a plant material can be carbonized is delivered into a vacuum tank filled with nitrogen, and carbonization is carried out for 3 to 6h at 500 to 1800 DEG C so as to obtain carbon blocks; b, the carbon blocks are delivered into a high speed shearing machine for shearing at a rotating speed of 3800 to 24000rpm so as to obtain an ultrafine powder with a particle size ranging from 200 to 500nm; c, the obtained ultrafine powder is delivered into a container filled with ammonia gas and an inert gas, is subjected to deoxygenation at 300 to 400 DEG C for 4 to 10h, and then is subjected to ruthenium permeating modification for 30 to 180min; and d, the ultrafine powder obtained via ruthenium permeating modification is delivered into a low frequency vibration separator filled with ammonia gas for vibration separation at 10 to 50Hz so as to obtain a semitransparent flake-like powder. The method is capable of producing the carbene material with characteristics extremely similar to that of graphene, and the used raw material is a reproducible natural plant material.

Description

technical field [0001] The invention belongs to the field of graphene, and in particular relates to a method for extracting carbonene materials from plants. Background technique [0002] Graphene is a carbon atom with sp 2 Hybrid orbitals form a hexagonal planar film with a honeycomb lattice, a two-dimensional material with a thickness of only one carbon atom, and is a general term for single-layer graphene, double-layer graphene and multi-layer graphene. [0003] Graphene is the thinnest and hardest nano-material known, it is almost completely transparent, only absorbs 2.3% of light; the thermal conductivity is as high as 5300W / m·K, which is higher than that of carbon nanotubes and diamonds. Mobility over 15000cm 2 / V·s is higher than that of carbon nanotubes or silicon crystals, and its resistivity is only about 1Ω·m, which is lower than that of copper or silver. It is the material with the smallest resistivity in the world. Because of its extremely low resistivity and ...
