Abstract

The invention provides carbon nanotube paper and a making method thereof. The making method of the carbon nanotube paper comprises the steps that a carbon nanotube is mixed with an activating agent, subjected to ultrasonic concussion, and stirred to form suspension liquid of the carbon nanotube firstly; then the suspension liquid is washed, filtered by a magnetic filter, and subjected to continuous heating finally, so that the tightly arranged carbon nanotube paper with a carbon nanotube structure and an undamaged shape is obtained. The carbon nanotube paper has the characteristics of integral structure, uniformity and tightness in arrangement, high electrical conductivity, good mechanical strength and the like; the shape, the size and the thickness of the carbon nanotube paper can be controlled through controlling a raw material ratio, so that different carbon nanotube paper meeting requirements is made. The carbon nanotube paper can serve as anode materials of a super capacitor and a Li ion electrode, and electrode materials in a nanofiltration membrane, a sensor and electrochemical synthesis, thereby having a good application prospect.

Description

【Technical field】

[0001] The invention relates to carbon nanotube paper and a preparation method thereof, in particular to a carbon nanotube paper with no loss of carbon nanotube structure and shape and a preparation method thereof. 【Background technique】

[0002] Since the advent of carbon nanotubes (CNTs) in 1991, due to its unique physical and chemical properties, it has become a research hotspot at home and abroad. Carbon nanotubes have low impedance due to their good mechanical properties and fast electron transfer speed, so they have good application prospects in high-performance composite materials and other fields. Carbon nanotubes are intertwined by the van der Waals force between tubes to form a paper-like carbon nano-thin layer, called carbon nanotube paper (also known as Bucky paper, BP, Bucky paper). Since carbon nanotube paper is a carbon nanotube layer formed by intertwined carbon nanotubes, it is a self-supporting (Free-standing) structure. Compared with car...
