Abstract

The invention relates to the technical field of nano materials, in particular to an attapulgite nano material and a preparation method and application thereof. The preparation method of the attapulgite nano material comprises the following steps that attapulgite and a nano material are mixed and then subjected to ultrasonic shock treatment, and the attapulgite nano material is obtained. The preparation method is easy to implement, strong acid is not needed for heating, and pollution to the environment and damage to nano materials are lowered. In addition, the attapulgite and carbon nano tubes can form mixed micelles adsorbed on the surface of the carbon nano tubes, and the micelles mutually repel each other through the electrostatic effect, and the agglomeration and mutual intertwining of the carbon nano tubes are hindered.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to an attapulgite nanomaterial and its preparation method and application. Background technique [0002] Carbon nanotubes have been widely used due to their chemical inertness, large specific surface area, variable structure, and adjustable physical and chemical properties. Can be divided into multi-walled carbon nanotubes (multiple-walled carbon nanotubes, MWNTs) and single-walled carbon nanotubes (single-walled carbon nanotubes, SWNTs). However, the suspension stability of carbon nanotubes in the carbon nanotube dispersion is poor, the sedimentation speed is fast, easy to agglomerate, and difficult to disperse, which limits the application range of carbon nanotubes. At present, to solve the problem of poor dispersion of carbon nanotubes in solution, there are mainly methods such as using concentrated acid to treat carboxylation, adding surfactants, adding coupling agents, a...
