Special Issue Information

Dear Colleagues,

One- and two-dimensional (1D and 2D) nanomaterials have attracted a broad interest within the scientific community over the past few decades due to their extraordinary electrical, optical, mechanical, thermal, and chemical properties. The need to replace Indium Tin Oxide (ITO) in transparent electrodes arises from the potential future scarcity of Indium and the consequent rising cost, as well as its related environmental issues. The high electrical conductivity, along with low optical conductivity, have made 1D and 2D nanomaterial network films promising candidates for the development of transparent conducting elements that may replace ITO. These are key components in devices like displays, touch screens, LEDs or solar cells, which are ubiquitous in everyday life. Moreover, nanomaterial films offer flexibility, which is a potential value add that ITO does not offer, and expands the possible applications towards flexible electronics.

Significant progress has been made over the last years in developing nanomaterial-based transparent electrodes. This Special Issue of Applied Sciences presents the latest developments in the fabrication and application of such components throughout the worldwide scientific community, identifies existing technology gaps, and helps draw a path forward for large scale industrial application.

Transparent electrodes are essential elements of devices bearing a screen or display, as well as solar cells, LEDs etc. To overcome the drawbacks presented by indium tin oxide, nanomaterials have been proposed for a long time as alternatives. Metal nanowires are particularly interesting for their high intrinsic electrical conductivity. Copper nanowires have attracted wide interest due to the low cost and high abundancy of the starting material. However, they are easily oxidized thus suitable strategies must be devised to prevent it. This review discusses the fundamental properties and challenges of copper nanowires, focusing on the efforts made to make them longer and thinner then the strategies to prevent oxidation and to join them in the network are presented. After that, mechanical properties are summarized and applications are presented, before conclusions and perspectives are finally given. Full article

Silver nanowire networks are attractive for flexible transparent electrodes due to their excellent optical transparency and electrical conductivity. Their mechanical reliability under bending is an important feature for the adoption of silver nanowire transparent electrodes for flexible electronics. Therefore, various studies have been conducted to understand the deformation behavior of silver nanowire networks, which are different from those of bulk silver or silver thin films. The focus of this review is to elucidate the deformation mechanism of silver nanowire networks under high cycles of bending and to present ways to improve the mechanical reliability of silver nanowire transparent electrodes.
