1、 Background introduction: The significance and challenges of embedded metal mesh flexible transparent conductive film
With the popularization of electronic products and the demand for lightweight and flexibility
Transparent conductive filmThe requirements are also increasing. Traditional transparent conductive films such as ITO thin films have problems such as short service life, fragility, and high cost. Therefore, high-performance embedded metal mesh flexible transparent conductive films have emerged. This technology uses two main processes, 3D printing and hot stamping, to meet the needs of large-scale manufacturing while also possessing conductivity, transparency, and flexibility. It can be applied in various fields such as smart electronic devices and photovoltaic cells.
2、 No need for expensive equipment, reducing production costs
Cost effectiveness is currently one of the important factors affecting the popularization of technology applications. The high-performance embedded metal mesh flexible transparent conductive film adopts a two-step process of 3D printing and hot stamping, without the need for expensive equipment such as photolithography and nanoimprinting, effectively reducing production costs. Meanwhile, due to the high utilization rate of materials, waste of materials is reduced, making it more environmentally friendly and sustainable.
3、 Simple process and high production efficiency
High performance embedded system
Metal grid flexible transparent conductive filmThe manufacturing process is simple and efficient. The entire process only requires two main processes, 3D printing and hot stamping, which greatly improves production efficiency compared to the complex and multi-step traditional technology. Moreover, 3D printing technology has high automation and flexibility, which can achieve diversified product production and better meet personalized market demands.
4、 There are various types of metal mesh materials that can be applied, expanding the scope of application
High performance embedded metal mesh flexible transparent conductive film can be applied to various metal mesh materials, and the viscosity is almost unlimited. This means that we can choose metal grids of different materials, such as copper, silver, etc., and prepare them according to specific needs. This feature greatly expands the types of metal mesh materials that can be applied, meeting the needs of different industries.
5、 Realize seamless large-scale manufacturing and overcome existing technological challenges
Traditional techniques often encounter difficulties in preparing large-sized flexible transparent conductive films, such as the inability to achieve the manufacturing of large-sized seamless micro nano masks or molds. The high-performance embedded metal mesh flexible transparent conductive film adopts electric field driven jet micro 3D printing technology, which enables the manufacturing of large-sized films without the need for splicing or other methods. This breakthrough not only solves the manufacturing problem, but also improves the reliability and stability of the product.
