| Research Abstract |
In this research, we prepared ITO-free transparent conductive films for substitution of ITO to solve exhaustion problems of rare metals resources. We have previously reported that preparation of polymer network patterns by using self-organization process. By using this technique, we prepared gold line-and-space pattern structures by dewetting of gold nanoparticle dispersion. This gold line-and-space pattern structures shows great potentials for use as transparent conductive films. Visible wavelength transmittances of gold line-and-space pattern structures were ca. 80 %, conductivity was same as ITO transparent conductive films, and also we can prepare gold line-and-space pattern structures on flexible polymer substrates. As these results suggest this gold line-and-space pattern structures can be used as ITO-free transparent conductive films.
