Description
Technical Field
The invention belongs to the technical field of photoelectric material preparation, and particularly relates to a preparation method of a highly-oriented one-dimensional conductive filler-based TCF material.
Background
A transparent conductive thin film (TCF) having both excellent transparency and conductivity is a key index for realizing high performance of an optoelectronic device, and actually, TCF has also attracted great attention as a flexible electrode in fields such as a touch screen panel, a flexible organic solar cell, and an organic light emitting diode. The one-dimensional conductive filler (metal nanowires, carbon nanotubes, etc.) has ultrahigh conductivity, light transmittance, flexibility and large length-diameter ratio, so that the one-dimensional conductive filler is widely used for manufacturing TCF (thin film transistor) by various solution-based spin coating, spray coating, vacuum filtration and bar coating.
However, in the conventional preparation process, the one-dimensional conductive filler is mainly randomly distributed on the surface of the matrix, so that various problems inevitably occur, such as the coffee ring phenomenon easily occurs, and the surface roughness is increased; the volatilization of the solvent needs to be assisted by high temperature; the random distribution of the conductive network can not combine high light transmission and conductivity, and only the threshold permeability value of the conductive network can be reduced, so that the balance between light transmission and conductivity is achieved. Of course, in theory, the ordered arrangement distribution of the TCF conductive network is the most effective means for solving the above problems, and corresponding prior arts also include a solution method-based langmuir-blodgett technique, a nano-groove pre-orientation method, a doctor-blade printing technique, a shear induced orientation technique, and the like to improve the ordered arrangement distribution of the TCF conductive network. However, these methods also have some disadvantages, such as the preparation means requires high precision and complicated preparation process, additional process means such as template pre-preparation, template transfer or pre-growth of conductive fillers are required, the evaporation rate of the solvent is slow, the preparation efficiency is reduced, and the scale-up preparation is impossible. Therefore, research and development of a method for preparing uniform TCF is an important subject of research and development in the industry.

During operation, an atomizing nozzle connected with a high-pressure air source can be used as an atomizing mechanism, the aqueous dispersion of the one-dimensional nano material is uniformly sprayed on the flexible film substrate on the bearing main body, the bearing main body is driven by a motor to move at a uniform speed for turnover, and meanwhile, the atomizing nozzle can be driven by the X-axis linear driving mechanism to set a horizontal moving speed and a horizontal moving displacement in the same axial direction according to the axial length of the bearing main body, so that the solution can be uniformly sprayed on the flexible film substrate. Before spraying, the distance between the atomizing nozzle and the flexible film substrate can be adjusted under the driving of the Y-axis linear driving mechanism.
