Accounts of Chemical Research, 2018
Research on graphene abounds, from fundamental science to device applications. In pursuit of complementary morphologies, formation of graphene foams is often preferred over the native two-dimensional (2D) forms due to the higher available area. Graphene foams have been successfully prepared by several routes including chemical vapor deposition (CVD ...

Laser-Induced Graphene Triboelectric Nanogenerators
ACS Nano, 2019Triboelectric nanogenerators (TENGs) show exceptional promise for converting wasted mechanical energy into electrical energy. This study investigates the use of laser-induced graphene (LIG) composites as an exciting class of triboelectric materials in TENGs. Infrared laser irradiation is used to convert the surfaces of the two carbon sources, polyimide

Flexible and Stackable Laser-Induced Graphene Supercapacitors
ACS Applied Materials & Interfaces, 2015In this paper, we demonstrate that by simple laser induction, commercial polyimide films can be readily transformed into porous graphene for the fabrication of flexible, solid-state supercapacitors. Two different solid-state electrolyte supercapacitors are described, namely vertically stacked graphene supercapacitors and in-plane graphene ...

Laser-Induced Solid-Phase Doped Graphene
ACS Nano, 2014There have been numerous efforts to improve the performance of graphene-based electronic devices by chemical doping. Most studies have focused on gas-phase doping with chemical vapor deposition. However, that requires a complicated transfer process that causes undesired doping and defects by residual polymers. Here, we report a solid-phase synthesis of

High-Resolution Laser-Induced Graphene from Photoresist
ACS Nano, 2021The fabrication of patterned graphene electronics at high resolution is an important challenge for many applications in microelectronics. Here, we demonstrate the conversion of positive photoresist (PR), commonly employed in the commercial manufacture of consumer electronics, into laser-induced graphene (LIG).

Laser-induced transformation of graphene into graphene oxide nanospheres (GONs)
Materials Research Bulletin, 2019Abstract In this work, we report a template-free synthesis of graphene oxide nanosphere (GONs) by the laser ablation of graphene in ethanol. The GONs were formed by crumpling of graphene sheet under the infrared nanosecond pulsed laser irradiation. FESEM and HRTEM images of as-prepared GONs were recorded to analyse the morphological characteristics ...
