Carbon nanotube conducting slurry dispersion effect test apparatus

Abstract

The invention discloses a carbon nanotube conducting slurry dispersion effect test apparatus. The apparatus comprises a ceramic grinder, the ceramic grinder is filled with a carbon nanotube conducting slurry and a zirconium oxide bead; the inner wall surface of the ceramic grinder is provided with three electrode groups with different depths, every electrode group comprises an electrode a and an electrode b, a distance between the electrode a and the electrode b is constant, and the electrode a and the electrode b are positioned in the same liquid level depth of the carbon nanotube conducting slurry; the electrodes a and the electrodes b in all the electrode groups are led out through leading wires, and form a parallel circuit which is connected with a resistor; toggle switches are arranged in the parallel circuit; and a timer is arranged in the resistor, and the resistor is connected with a stirring motor. The apparatus can accurately and effectively judge the dispersion effect of the a carbon nanotube slurry, can give the dispersion stirring time node of the carbon nanotube slurry, can automatically control the stirring node of a stirring shaft, and avoids excess stirring.

Description

technical field [0001] The application relates to an auxiliary testing device in the production process of carbon nanotube slurry, in particular to a testing device for the dispersion effect of carbon nanotube conductive slurry. Background technique [0002] As a one-dimensional nanomaterial, carbon nanotubes are light in weight, perfectly connected in a hexagonal structure, and have many unusual mechanical, electrical, and chemical properties. [0003] Carbon nanotubes have good mechanical properties. The tensile strength of CNTs reaches 50-200GPa, which is 100 times that of steel, but the density is only 1 / 6 of steel, which is at least an order of magnitude higher than that of conventional graphite fibers; its elastic modulus can reach 1TPa , equivalent to the modulus of elasticity of diamond, about 5 times that of steel. For carbon nanotubes with a single-walled ideal structure, the tensile strength is about 800 GPa. Although the structure of carbon nanotubes is similar...
