Carbon nano paper and its preparation method and application

Abstract

The invention relates to carbon nano paper and a preparation method and application thereof. The carbon nano paper comprises two or more functional layers which are successively stacked, wherein each functional layer is prepared from a carbon nano material; the diameters of the carbon nano materials in the various functional layers are successively increased according to the stacking sequence; at least one functional layer further comprises nano particles of metal or metal oxide deposited on the surface of the carbon nano materials. The carbon nano paper has the characteristics of large specific surface area, excellent electrical conductivity and excellent breathability. Different kinds of metals are used for preparing different series of carbon nano paper products of load metal or metal oxide nano particles, and by the characteristic of the metal nano particles, the carbon nano paper can be applied to various fields.

Description

technical field

[0001] The invention relates to the field of carbon nanometer materials, in particular to carbon nanometer paper and its preparation method and application. Background technique

[0002] Carbon nanomaterials are carbon nanoscale allotropes, mainly including carbon nanotubes, carbon nanofibers, graphene, carbon nanohorns and fullerenes. Carbon nanomaterials have excellent electrical and mechanical properties, and are nanoscale and light in weight. They have a wide range of applications in the fields of energy storage electrodes, catalyst supports, reinforced composite materials, wave-absorbing and electromagnetic shielding materials, flame-retardant materials, microelectronics, and filtration. the use of.

[0003] Carbon nanopaper (also known as Bucky paper, Bucky paper) is a self-supporting paper-like material formed by cross-linking and polymerizing carbon nanomaterials (carbon nanotubes or carbon nanofibers). On the one hand, it retains carbon Nanomateria...
