Problems solved by technology

However, the unavoidable problem that follows is that the TCF prepared with silver nanowires has a large surface roughness and poor adhesion. To solve this problem, Yu Chunyu's research group at Harbin Institute of Technology used PEDOT:PSS as a modification AgNWs / PEDOT:PSS composite TCF with excellent electrical conductivity was prepared; Wang’s group coated ZAO on the surface of silver nanowires to prepare AgNWs / ZAO composite TCF; some researchers also used PVC and other polymers to prepare TCF based on The composite TCF of silver nanowires, although the composite TCF of silver nanowires can effectively solve the problems of poor adhesion and surface roughness to a certain extent, it also reduces the visible light transmittance of TCF and affects its work function.

Abstract

The invention relates to a preparation method of silver nanowire transparent conducting thin film based on a three-dimensional microstructure. The preparation method comprises the steps that S1, silver nanowires are prepared; S2, the three-dimensional microstructure is established on a glass substrate; S3, the silver nanowires with certain length-diameter ratio are embedded into the three-dimensional microstructure of the glass substrate. The preparation method adopts a hydrothermal method, silver nitrate is used as a silver source, glucose is used as a reducing agent, ferric sulfate is used as an inducing agent and polyethylene pyriloxanone (PVP) is used as a morphology inducing agent to prepare the silver nanowires with adjustable length-diameter ratio, and the silver nanowire transparent conducting thin film is prepared by using the silver nanowires different in length-diameter ratio. In addition, the silver nanowires are embedded into the three-dimensional microstructure of the glass substrate, so that the light transmittance of the film is improved and is higher than 91.3%; in addition, the preparation method integrates internal portion layer embedding, heating and curing of the short silver nanowires and external layer modified long silver nanowires, the photoelectric property of the conductive thin film is further improved, and its resistance is about 20 omega / sq.

Description

technical field [0001] The invention relates to the technical field of nanomaterials, in particular to a method for preparing a silver nanowire transparent conductive film based on a three-dimensional microstructure. Background technique [0002] Metallic transparent conductive films (TCFs) have broad application prospects in touch screens, displays, heaters, antistatic biosensors, new energy sources, solar cells, flexible electronics, and wearable electronics. At present, indium tin oxide (ITO) is generally used as the main transparent conductive electrode material in transparent conductive films. Usually, a layer of ITO is sputtered on the surface of the device substrate, and the formed TCF has high transmittance, excellent conductivity, and smooth surface. etc., but due to the brittleness of indium tin oxide material itself, its application in the field of flexible electronic devices and wearable devices is limited. [0003] At present, research on new thin film material...
