Graphene Synthesis from Organic Substrates: A Review

“…Figure shows how femtosecond direct laser writing may be used to create FsLIG microelectrodes in a single step upon natural leaves under ambient conditions. A powerful ytterbium-doped fiber femtosecond laser which produces light with the third harmonic wavelength of 346 nm was used for this process …”

“…Therefore, a revolutionary method for converting waste leaves into high-value goods might have a big influence on how our society develops sustainably. 74 According to a comprehensive study 74 on the outcomes of laser wavelength and formation of femtosecond-laser-induced graphene (FsLIG), a narrowly focused UV femtosecond laser beam is utilized to directly create arbitrary FsLIG patterns upon naturally fallen leaves in atmospheric air. UV wavelengths are best for this method due to leaves' strong UV photon absorption.…”

“…A powerful ytterbium-doped fiber femtosecond laser which produces light with the third harmonic wavelength of 346 nm was used for this process. 74 FsLIG on leaves' adaptability and universality open pathways to the creation of affordable, environment-friendly, flexible electronics based on graphene and encourage the creation of transient or eco-friendly electronics for a sustainable society.…”

“…Last but not least, leaves are very thin and flexible by nature; these qualities make them ideal for flexible and wearable electronics. Therefore, a revolutionary method for converting waste leaves into high-value goods might have a big influence on how our society develops sustainably …”

In Situ Laser-Induced 3D Porous Graphene within Transparent Polymers for Encapsulation-Free and Tunable Ultrabroadband Terahertz Absorption

“…However, the development of flexible encapsulation treatments for heterogeneous structures remains challenging owing to potential delamination issues of functional and encapsulation layers during device stretching and bending process . This challenge persists across studies on electromagnetic shielding, including those involving other flexible devices. − Consequently, the pursuit of a porous material capable of surmounting these hurdles while facilitating efficient manufacturing is imperative for the advancement of ultrathin, pliable electromagnetic absorbers.…”
