Embodiment

[0052] This embodiment proposes a single-oriented carbon nanotube jet printing arrangement method, the specific steps are as follows figure 1 Shown:

[0053] S1. Immerse the substrate in the piranha solution: take a piece of SiO 2 sheet, where SiO 2 The thickness of the layer is 500nm, followed by ultrasonic cleaning with acetone, ethanol, and water for 20 minutes, rinsed with a large amount of ultrapure water after each ultrasonic wave, then immersed in piranha solution, and treated in piranha solution at 80°C for 10 minutes; finally Rinse with a large amount of ultrapure water and blow dry with nitrogen. The piranha solution is a strong oxidizing mixed solution of concentrated sulfuric acid: hydrogen peroxide = 3:1, which can convert SiO 2 The organic matter on the surface is oxidized and greatly increases the number of hydroxyl groups on the surface of SiO2, increasing its wettability;

[0054] S2, immerse the substrate into the silane modification solution and let it st...

Abstract

The invention provides a single aligned carbon nano tube jet-printing arrangement method. The method comprises the steps that a substrate is modified with octadecyltrichlorosilane (OTS), so that the surface of the substrate has a hydrophobic property; precise control over the thin film position, the aligned density and patterning of aligned carbon nano tubes is achieved on the functional hydrophobic substrate through ink-jet printing, and a carbon nano tube thin film which is uniform in density and consistent in orientation and has different patterns is arranged. By means of the method, the carbon nano tube arrangement area of the size from several micrometers to the wafer level can be effectively controlled; the problems can be solved that in all existing arrangement methods, the arrangement position, the arrangement orientation, the arrangement density and the thin film array patterning of one-dimensional nano materials on the substrate cannot be efficiently and precisely controlled;the method can be widely used for preparing various high-performance photoelectric devices, logic circuits and functional thin films based on the carbon nano tubes, and the method also has a wide application prospect in the field of flexible wearable nano devices.

Description

technical field [0001] The invention belongs to the field of nano-processing, and in particular relates to a single-orientation carbon nanotube spray printing arrangement method. Background technique [0002] Carbon nanotubes are one-dimensional tubular molecules formed by curling graphene. It not only has the excellent mechanical properties, thermal properties, and high carrier mobility of graphene, but also has the characteristics of one-dimensional tubular properties and SP2 hybridization. The C-C bond structure and the unique helical structure exhibit excellent photoelectric properties, and have great application prospects in the fields of optoelectronic devices, integrated circuits, and functional thin films. However, in order to prepare high-performance carbon nanotube optoelectronic devices and logic circuits, and give full play to the excellent properties of a single carbon nanotube, it is key to develop a new arrangement technology to achieve a large area of ​​preci...
