The invention discloses a collecting for carbon nano tube dispersions and belongs to the field of carbon nano tube dispersion. The collecting device is composed of a carbon nano tube dispersion circulation pipeline, an oriented conveying device and a collecting and spraying device. The oriented conveying device is mainly composed of an oriented conveying device shell, a high-voltage power supply, a grounding device and electrodes. The collecting and spraying device is mainly composed of a water pump, a spraying nozzle, a porous filtering screen, a collecting and spraying device shell, a water inlet and drainage pipeline system and a collecting cylinder. The nano tube dispersion circulation pipeline is located inside the oriented conveying device, and the oriented conveying device and the collecting and spraying device are connected through a pipeline. The oriented conveying device can generate electrified particle air flow moving in an oriented mode and draw the carbon nano tube dispersions to the collecting and spraying device; the porous filtering screen is installed in the collecting cylinder, and by separating the collecting cylinder and the collecting and spraying device shell, the carbon nano tube dispersions gathered on the porous filtering screen after flushing can be obtained.
Description
technical field [0001] The invention relates to the collection of carbon nanotube dispersions, in particular to a collection device for obtaining carbon nanotube dispersions by a gas phase dispersion method, and belongs to the field of dispersion of nanometer materials. Background technique [0002] Carbon nanotubes are tubular substances with nanoscale diameters formed by curling graphite sheets according to a certain helical angle. It has a very large aspect ratio, and the heat exchange performance along the length direction is high, while the heat exchange performance in the vertical direction is relatively low. Through proper orientation, carbon nanotubes can synthesize anisotropic heat conduction materials. Due to the large van der Waals attraction, huge specific surface area, and very high aspect ratio between carbon nanotubes, carbon nanotubes generally exist in the state of entangled aggregates. , carbon nanotubes have a certain degree of agglomeration, which affect...
