Embodiment Construction

[0010] The method for modifying carbon nanotubes provided by the embodiments of the present invention comprises the following steps:

[0011] First, 1 part of carbon nanotubes is mixed with 10 to 100 parts of 30 to 70% polydioxyethylthiophene-polystyrene sulfonic acid (PEDOT-PSS) polymer aqueous solution in parts by weight;

[0012] Then, the above-mentioned mixed solution is heated to 30-60° C., and ultrasonically oscillated for 1-24 hours, so that the surface of the carbon nanotube is double-modified by polydioxyethyl thiophene and polystyrene xanthate.

[0013] The concrete steps of this embodiment are as follows:

[0014] (1) 2 grams (g) of dry carbon nanotubes were mixed with 200 milliliters (mL) of a 50% polyethylene glycol thiophene-polystyrene sulfonic acid (PEDOT-PSS) polymer aqueous solution. Wherein, the carbon nanotubes can be single-wall carbon nanotubes or multi-wall carbon nanotubes prepared by arc discharge method, laser melting method or chemical vapor deposi...

Description

【Technical field】 [0001] The invention relates to a method for modifying carbon nanotubes. 【Background technique】 [0002] Carbon nanotubes are a new type of nanomaterial discovered by Japanese scientist Professor Iijima in 1991. They are tubes rolled into graphene sheets. Carbon nanotubes are classified into single-walled carbon nanotubes and multi-walled carbon nanotubes. [0003] Because carbon nanotubes have excellent properties in mechanics, electronics, physics, chemistry, etc., such as unique metal or semiconductor conductivity, extremely high mechanical strength, high-capacity hydrogen storage capacity and adsorption capacity, field electron emission performance, orientation Thermal conductivity and strong broadband electromagnetic wave absorption characteristics have made carbon nanotubes receive great attention from the fields of physics, chemistry and material science, as well as high-tech industry departments, and at the same time promote the extensive research ...
