Graphene’s infusion in textiles is the future of wearable electronic clothing

Scientists have successfully printed washable and stretchable electronic circuits into fabric, paving the way for smart textiles and wearable electronics Original source | [...]

Nanotechnology is a key tool to increase the capabilities of electronics devices while reducing their weight and thickness of the screens, and power consumption. Nanoelectronic applications can increase density memory chips or reduce the size of transistors used in integrated circuits.
For example, carbon nanotubes are used for building transistors with lower dimensions, while graphene films are used to enable very high speed for those devices.
Generally thermoplastic polymers are insulator materials with conductivity values of the order of 10-16 to 10-14 S/cm and additional fillers (e.g. metallic particles or carbon black) are needed to enhance their electrical conductivity. Recently, nanocomposites based on carbon nanostructures and thermoplastic polymers have been proposed. Electrical conductivity values of the order of semiconductors (10-10-102 S/cm) were found being suitable for their application in flexible transparent transistors, thin film loudspeakers, capacitors, solar cells, among other applications.
Graphene–conjugated polymer (CP) nanocomposites have shown potential applications in supercapacitors, photovoltaic devices, OLEDs, and biosensing devices. In addition to graphene, other 2D materials, such as metal dichalcogenide nanosheets, have recently attracted tremendous attention due to their outstanding performance in device applications.

However, the resulting material is grainy and has poor electrical properties. Researchers led by Jaeho Kim and Hiromoto Itagaki at the National Institute of Advanced Industrial Science and Technology (AIST) found that they could grow higher-quality graphene by more carefully controlling the plasma.

Because of the strong infrared (IR) absorption of CNTs, the printed patterns can be selectively sintered by noncontact IR radiation efficiently to show great electrical conductivity. The electrical resistance of the written patterns on paper also show an insignificant increase after bending, folding, and crumpling. Furthermore, the conductive composite exhibits great healability after destructive damages. The conductivity of the damaged patterns after severe folding or […]
