Since silver has excellent electrical conductivity, preferably, in a preferred embodiment of the present invention, the metal micro-nano material is si...

Embodiment 1

[0062] Metal micro-nano material-silver nanowire transparent conductive film matrix, which is prepared by the following method:

[0063] (1) First configure a polyol solution of PVP with a certain molecular weight, heat it in a water bath and stir it magnetically to dissolve it completely, and cool it to room temperature. Configure AgNO 3 The polyol solution was placed on a magnetic stirrer to dissolve it completely. At the same time, configure a certain concentration of NaCl solution to completely dissolve it. When mixing the solution, pay attention to the order of addition: first mix the polyol solution of a certain molecular weight PVP and AgNO 3 Mix the polyol solution with a glass rod at room temperature, then add a certain amount of NaCl solution, and stir evenly.

[0064] Transfer the uniformly mixed solution to the reactor, and use the alcohol thermal method to prepare silver nanowires. The first choice is a closed system, which can block the oxygen in the air. Air...

Abstract

The invention provides a preparation method of metal micro-nano material transparent conductive film patterning and application thereof, and relates to the field of preparation of metal micro-nano material transparent conductive films. The preparation method specifically includes the following steps: a polar solution containing a metal micro-nano material is coated on a flexible film, after dryinghydrophilic treatment, a polar solution with certain viscosity with the flexible film is adopted to draw arbitrary patterns, and finally, microwave treatment of 0.3 GHz to 300GHz is carried out. A heating effect is caused by use of the interaction of microwaves with polar molecules on the metal micro-nano material, thus the metal micro-nano material is heated until the material fuses, and the properties of the metal micro-nano material transparent conductive film can be effectively improved. The preparation method does not need an additional printing coating process, the required preparationtreatment time is short and the efficiency is high, large-scale continuous production can be achieved, and thus the preparation method is suitable for industrial production.

Description

technical field [0001] The invention relates to the field of preparation of transparent conductive films of metal micro-nano materials, and in particular to a preparation method and application thereof for patterning transparent conductive films of metal micro-nano materials. Background technique [0002] In today's information age, our daily life is inseparable from various electronic devices, and transparent conductive films (TCFs) with high conductivity and high transparency are crucial to the performance of various electronic devices. Electronic devices such as touch screens, flat-screen TVs, e-readers, smartphones, smart glass, organic solar cells, and liquid crystal displays cannot do without transparent conductive materials. Among all transparent conductive materials, indium tin oxide (ITO) is the most commonly used in the current electronics industry. Due to its fragility and brittleness, ITO is widely used in flexible displays, flexible touch screens, flexible solar...
