Formation of Large-Scale Flexible Transparent Conductive Films Using Evaporative Migration Characteristics of Au Nanoparticles

Abstract

To sustain the growing demand of transparent conductive films for wide applications, such as flat panel displays, a much more cost-effective film is required over the widely used indium tin oxide film. Here we developed a promising method to manufacture a cost-effective flexible transparent conductive film of high performance by first making grid-iron patterns of thin lines on a large scale using evaporative migration characteristics of gold nanoparticles, and then by burying the grid-iron pattern into a poly(ethylene terephthalate) film.

Hydrogen reduced graphene oxide/metal grid hybrid film: towards high performance transparent conductive electrode for flexible electrochromic devices

“…Indium tin oxide (ITO), the most widely used transparent conductor, is inadaptable for the use in the next generation flexible optoelectronics due to its brittle nature. Various materials such as carbon nanotubes [4], graphene [5][6][7], the metal grid [8,9], metal nanowires [10,11] and conductive polymers [12] are hence investigated to replace ITO. Among these candidates, the metal grid is quite promising because of its excellent electrical and optical properties [13].…”

Fabrication of non-close-packed colloidal monolayers by convective self-assembly using cationic polyelectrolyte-grafted silica particles

“…The colloidal layers have attracted much attention because of their potential applications, such as photonic crystals [1,2], chemical and biosensors [3,4], optical devices [5][6][7], and data storages [8], and have been extensively investigated so far [9][10][11][12][13]. Although the properties of such colloidal layers primarily depend on the particle arrangement as well as the particle types, most colloidal layers in the reported studies have only a close-packed (CP) structure.…”
