Problems solved by technology

However, high-purity (99% semiconducting or 99% metallic) carbon nanotubes are extremely expensive. For example, the 99% semiconducting carbon nanotubes of NanoIntegris, which is more commonly used in the nano field, sell for $799 per milligram, and the product itself There are also certain restrictions on the size, such as the average length of 1 micron, etc., which are the bottlenecks for the industrialization of carbon-based devices (chips)

Abstract

The invention provides a method for growing carbon nanomaterials. The method comprises the following steps: preparation of a carbon nano raw material dispersing solution, dispersing a carbon nano raw material into a first solution, preparation of a carbon nanoparticle dispersing solution, carrying out physical and / or chemical treatment on the carbon nano raw material dispersing solution, transferring carbon nanoparticles in the carbon nanoparticle dispersing solution to a substrate by virtue of the carbon nanoparticle dispersing solution, growing the carbon nanomaterials on the substrate based on the transferred carbon nanoparticles.

Description

technical field [0001] The present application relates to the field of nanomaterials, in particular to a method for growing carbon nanomaterials. Background technique [0002] Carbon nanomaterials such as carbon nanotubes are tubular one-dimensional nanomaterials formed by winding single-layer or multi-layer graphene sheets. Carbon nanotubes have excellent optical, electrical, thermal and mechanical properties, and their current densities are as high as, for example, 10 9 A / cm 2 , the electron mobility can reach for example 10000cm 2 / V·s, the thermal conductivity is as high as 6600W / mK, and the Young's modulus is as high as 1TPa, which is about 5 times that of steel. Based on the above excellent properties, carbon nanotubes can be used in many fields such as electricity and mechanics. [0003] At present, the main methods for preparing carbon nanotubes are: arc discharge method, laser burning candle method, chemical vapor deposition method, etc., and chemical vapor depo...
