Presentation Title:

Gold Nanoparticle Inks for Room-Temperature Printing Electronic Devices

Time: TBD

Presentation Abstract:

Metal nanoparticle inks have already been widely investigated because of their emergent applications in flexible electronics. In our current researches, we focus on the development of gold nanoparticle inks modified with -conjugated molecules for printing electronic devices at room temperature as shown in Figure 1a. [1-4] The resolution as high as 1 micron was realized at a large scale. In addition, this strategy can be implemented at ambient atmosphere so that a wide variety of substrates, like polymer, paper and biomaterial can be used as shown in Figure 1b-1d. Therefore, this process will be promising for low-cost, high-efficiency printing and manufacturing of high-performance flexible IoT (Internet of Things) devices, including organic transistor [1-3], non-volatile memory and wearable sensor [4].
