“…By taking advantage of a polymer's nature, all kinds of excellent structures with the uniform size of the 0D micro-ball can be synthesized. Based on electrostatic interactions, RGO would cover the polymer balls to produce polymer ball @RGO nanoparticles [128][129][130][131]. Due to the bending of graphene sheets by the van der Waals attractive force, the PMMA ball @ RGO-based tactile sensor, at pressures < 1 torr, showed an increased resistance value [131].…”

“…Graphene offers great potential for electronics, optoelectronics, and energy storage applications due to its high charge carrier mobility, large specific surface area, good chemical/physical stability, and biocompatibility . Graphene has been synthesized in various ways such as epitaxial growth on silicon carbide via sublimating Si atoms, chemical or solvothermal reductions of exfoliated graphite oxides, and chemical vapor deposition (CVD) from C‐containing gases . These methods are, however, still away from green manufacturing fulfilling all five criteria listed above .…”

Fast, simple, cost-efficient, eco-friendly, and design-flexible patterning of highquality graphene from abundant natural resources is of immense interest for the mass production of next-generation graphene-based green electronics. Most electronic components have been manufactured by repetitive photolithography processes involving a large number of masks, photoresists, and toxic etchants; resulting in slow, complex, expensive, less-flexible, and often corrosive electronics manufacturing processes to date. Here, a one-step formation and patterning of highly conductive graphene on natural woods and leaves by programmable irradiation of ultrafast high-photon-energy laser pulses in ambient air is presented. Direct photoconversion of woods and leaves into graphene is realized at a low temperature by intense ultrafast light pulses with controlled fluences. Green graphene electronic components of electrical interconnects, flexible temperature sensors, and energy-storing pseudocapacitors are fabricated from woods and leaves. This direct graphene synthesis is a breakthrough toward biocompatible, biodegradable, and ecofriendlily manufactured green electronics for the sustainable earth.
