Preparation methods, characteristics, and application fields of metal grid nano silver wires

Metal grid nano silver wire is a new typeTransparent conductive materialIt has become one of the research hotspots in the field of transparent electronic devices due to its high transparency, low resistivity, flexibility, good stability, and controllability. This article will provide a detailed introduction to the preparation methods, characteristics, and application fields of metal grid nano silver wires.

1、 Preparation method of metal mesh nano silver wire
There are two main methods for preparing metal grid nano silver wires, namely template method and template free method:

1. Template method Template method is to take a layer of porous polymer film or alumina film as template, deposit silver nanowires on the surface of the template by electrodeposition or sol gel method, and then prepare silver nanowires with metal mesh by removing the template. This method is used to prepareMetal grid nano silver wireIt has high transparency and low resistivity, but the preparation process is relatively complex, requires the use of expensive template materials, and cannot achieve large-area preparation.

2. Template free method Template free method is to directly prepare silver nanowires with metal mesh under the condition of template free. The commonly used template free preparation methods include phase transformation, electrochemical deposition, solution method, and thermal evaporation method. Among them, phase transformation and electrochemical deposition are currently the most commonly used preparation methods. Phase change method is to gradually aggregate silver nanowires into a grid structure through optical laser or electron beam irradiation. The electrochemical deposition method involves depositing nano silver wires on the substrate surface through electrochemical deposition, forming a grid structure. Due to its simple preparation process, low cost, and ability to achieve large-area preparation, the template free method is widely used in industrial production.

1. High transparency metal mesh nano silver wires have high transparency, reaching up to 90%! On (MISS). Therefore, this material has become an ideal material for preparing highly transparent electronic devices.
2. Low resistivity metal grid nano silver wires have very low resistivity, typically between 10 ^ -4 and 10 ^ -3 Ω· cm. This low resistivity makes metal mesh silver nanowires an excellent conductive material for transparent electronic devices.
3. Flexible and malleable metal mesh nano silver wires have good flexibility and plasticity, which can bend and stretch without losing their conductivity, and can adapt to various shapes. This characteristic makes metal mesh silver nanowires widely applicable in fields such as wearable electronic devices and flexible electronic devices.

4. Good stability and controllabilityMetal grid nano silver wireHas good stability and controllability. During the preparation process, the morphology and size of silver nanowires can be controlled by adjusting the preparation conditions, thereby achieving precise regulation of their properties.
