摘要
In this research, we developed a simple direct friction method to fabricate transparent conductive films. It is a highly efficient technology as the progress consumes only several minutes from raw materials to final products and the adhesion between matrix and functional layer is strong. Flexible transparent conductive films (TCFs) based on graphite and polyethylene terephthalate substrates exhibited satisfied properties with surface resistivity from 5.07 to 83.6 K Omega sq(-1), optical transparency from 70 to 85% at 550 nm wavelength, and surface stability strong enough to protect them from aging under destructive surface treatments and bending. The main mechanisms are based on three key factors: (1) The lubrication property of two dimensional layered graphite, (2) Suitable wear properties of target transparent polymer matrix and rubbing medium, (3) A soft interlayer between glass block and rubbing medium. Furthermore, the samples show some potential applications such as flexible transparent heaters, flexible transparent humidity sensors and flexible transparent strain sensors. This technology has great potential to meet the requirements of transparent conductive electrodes for future optoelectronics: lightweight, flexible, economic, and especially compatible with large-scale manufacture. This method and the TCFs have some economical, environmental and energy saving advantages.
