Transparent Metal Mesh Conducting Film

Transparent Metal Mesh Conducting Film

Transparent Metal Mesh conducting electrode film is highly desirable for application in touch screen panels, flexible organic light diode (OLED), and wearable displays, sensors, and actuators. Metal Cu particles have been used for conducting electrodes by using various fabrication process.One-step direct nanoimprinting of gold particles and poly dimethylsilxane PDMS mold. Particles were also imported by PDMS mold on the polyimide film, and an organic field effect transistor device was fabricated . The direct imprinting process using a PDMS mold leaves metal particles on top of the film substrate so that it has limited application in transparent touch screen panel (TSP) fabrication, The direct imprinting and screen printing processes have the merits of being simple processes operated at ambient condition. However, they result in an embossed pattern on the film subtrate, so they may not withstand such hard mechanical stresses as bending and stretching.

Transparent Metal Mesh conducting electrode film is highly desirable for application in touch screen panels, flexible organic light diode (OLED), and wearable displays, sensors, and actuators.

Metal Cu particles have been used for conducting electrodes by using various fabrication process.One-step direct nanoimprinting of gold  particles and poly dimethylsilxane PDMS mold.

Particles were also imported by PDMS mold on the polyimide film, and an organic field effect transistor device was fabricated . The direct imprinting process using a PDMS mold leaves metal particles on top of the film substrate so that it has limited application in transparent touch screen panel (TSP) fabrication, The direct imprinting and screen printing processes have the merits of being simple processes operated at ambient condition. However, they result in an embossed pattern on the film subtrate, so they may not withstand such hard mechanical stresses as bending and stretching.


In this work, we synthesized both Cu nanoparticles for application to the large size touch screen panels. Indium tin oxide (ITO) has been widely used in transparent conducting electrodes (TCEs) to make small TSPs used in smartphones. However, ITO conductors cannot be used in large TSPs over 15 inches due to the trade-off between high transparency and low electrical resistance required for the operation of touch screen panels and the requirement of increasing the thickness of ITO thin films to lower the electrical resistance. Of the transparent conducting materials such as carbon nanotubes (CNTs), graphene, conducting polymer (PEDOT: PSS; poly (3,4-ethylenedioxythiophene) polystyrene sulfonate), and metal nanostructures, silver nanoparticles and silver-coated copper (Cu@Ag) nanoparticles have high potential for application in large TSPs, including flexible and stretchable versions. This is due to the suitability of the silver nanoparticle paste to the metal mesh-type transparent conducting electrode. In the metal mesh method, the transparent electrodes are patterned by using the trench filling process. In this method, a narrow engraved trench (~2.5 µ m) pattern is formed by coating a ultra violet (UV) curing resin on the substrate film and then pressing with a transparent mold followed by UV exposure and demolding. The gap between the trenches is over 100 µ m, so the visible light transmittance of the metal mesh film is over 88% while the resistivity of the Ag nanoparticle paste is less than 10 Ω · cm by the percolation mechanism. Metal mesh TCEs also have the merit of easy hard coating layer formation on top of atrench pattern layer filled with silver particles compared to the imprinting or screen printing processes with embossed silver electrode patterns.

It is the perfect sensing film that applied on a Multi Touch Panel, and fix very well with all Softwares and Windown Android systems,

It is Metal Mesh technology, and GFF structure, works well with stylus, and finger touches, its more sensitive and much longer service life than traditonal solutions, such as ITO and other touch technics.
