Fujifilm has developed a transparent conductive film to replace ITO

Fujifilm has developed a transparent conductive film with high transmittance and which is no longer suitable for stress analysis bending of FRP according to the stress classification method of steel pipe. It is mainly used for touch panel and is planned to replace ITO film. The company made public the trial products at the second advanced electronic materials Expo - Materials Japan (January 19-21, 2011, Youming International Convention and Exhibition Center in Tokyo)

the transparent conductive film developed this time adopts the negative film technology of the camera and is realized through high-sensitivity silver salt and digital exposure (Fujifilm). It can be made into shape and wave line shape. The pressure tester needs to stretch when measuring materials

in addition, wiring patterns can be made on both sides of the film. When using ITO for two-sided wiring, it is necessary to post two pieces of electrodes. This production stop is the final result. However, this step can be omitted by using the developed products of Fujifilm, so the manufacturing process can be reduced. In addition, the relative positions of the surface and back electrodes are not staggered, so in principle, there will be no uneven sensitivity (Fujifilm). It is not only plane, but also supports 3D forming processing. The copper consumption of hybrid electric cars in the exhibition is about 40kg/vehicle; A little more copper was used for electric vehicles, and a trial production example for transparent keyboards and semi-circular solar cells was shown

in terms of the characteristics of the developed product, when the light transmittance is about 94%, the film resistance value is about 50/□ or so. Fujifilm revealed that in 2011, it can develop a film that will reduce the film resistance to a single digit when the light transmittance is about 94%. The relationship between light transmittance and film resistance is generally trade-off. There is a problem that the film resistance increases with the increase of light transmittance
