“…These include the dispersion of 2DMs directly in solvents like NMP or DMF without binder,[61a,170b] and the use of binders as viscosity modifiers and stabilizers. Commonly selected binders include EC[58–60,61b,173] and ethylene glycol. [61a,62,170a] However, UILPE in high boiling point solvents is unsuitable for printing due to its low viscosity and limited ink concentration.…”

2D materials (2DMs), which can be produced by exfoliating bulk crystals of layered materials, display unique optical and electrical properties, making them attractive components for a wide range of technological applications. This review describes the most recent developments in the production of high-quality 2DMs based inks using liquid-phase exfoliation (LPE), combined with the patterning approaches, highlighting convenient and effective methods for generating materials and films with controlled thicknesses down to the atomic scale. Different processing strategies that can be employed to deposit the produced inks as patterns and functional thin-films are introduced, by focusing on those that can be easily translated to the industrial scale such as coating, spraying, and various printing technologies. By providing insight into the multiscale analyses of numerous physical and chemical properties of these functional films and patterns, with a specific focus on their extraordinary electronic characteristics, this review offers the readers crucial information for a profound understanding of the fundamental properties of these patterned surfaces as the millstone toward the generation of novel multifunctional devices. Finally, the challenges and opportunities associated to the 2DMs' integration into working opto-electronic (nano) devices is discussed.

“…The increase in the conductivity of such fi lms after laser annealing is related to the reduction of the structural disorder as confi rmed with the help of Raman spectroscopy. [ 64 ] Simulations of temperature dynamics after laser irradiation were also studied in our works. The transient temperature distribution in GO fi lms was simulated using pulsed laser irradiation (t = 10 ps) with a wavelength of 1064 nm and a Gaussian temporal beam profi le applying the software COMSOL Multiphysics, and the results are presented in Figure 10 .…”

the manipulation of graphene and its derivatives occupy a relatively insignifi cant part, i.e., less than 1%. The fi rst publications on graphene modifi cation with laser irradiation appeared in 2008, however, since 2010, the number of publications has risen exponentially.Graphene oxide (GO) has emerged as a versatile material for nanocarbon research. Several types of oxygen-containing functional groups present on the basal plane, and the sheet edge allows GO to interact with a broad range of organic and inorganic materials. [ 9 ] Furthermore, GO is an abundant and low-cost material synthesized from graphite or graphite oxide; it retains a layered structure but, at the same time, it can be characterized by the loss of electronic conjugation caused by the oxy groups at the edge or plane defects. GO has a potential use in energy, [ 10 ] electronics, [ 11 ] molecular sensing areas, [ 12 ] catalysis, [ 13 ] etc. Moreover, it can be reduced chemically or thermally in order to achieve graphenelike properties. [ 14 ] The material produced during such a procedure is usually referred to as "reduced GO" (rGO). However, residual defects such as remnant oxygen atoms, [ 15 ] Stone-Wales defects (pentagon-heptagon pairs), [ 16 ] and holes [ 17 ] appearing due to the loss of carbon (in the form of CO or CO 2 ) from the basal plane [ 18 ] limit the electronic quality of rGO.A laser is a powerful tool which is used for various applications in industry, medicine, science, and material processing. [ 19 ] It is usually employed in different processes such as ablation, etching, cutting of various materials, as well as direct A dramatic rise in research interest in laser-induced graphene oxide (GO) reduction and modifi cation requires an overview of the most recent works on this subject. Typical methods for the recognition and confi rmation of modifi ed graphene and its derivatives, such as Raman, Fourier-transform infra-red (FTIR), X-ray photoelectron (XP), and ultraviolet-visible (UV-vis) spectroscopies, are introduced briefl y in this review. A major part of the survey is devoted to the main modifi cation ways and the laser parameters used in the literature. A discussion of possible reduction and modifi cation mechanisms is also presented. Recent applications, especially in the biomedical fi eld such as cell therapy treatment, as well as signifi cant results of GO modifi cation, are discussed in detail. Finally, perspectives for the application of laser-induced GO modifi cations in passive THz photonics and biomedicine are briefl y addressed.

“…Secor and co-workers proposed a graphene ink-nitrocellulose electrochemical sensor for H 2 O 2 determination [33]. Several works have demonstrated that a post treatment of the graphene ink could improve its conductivity through thermal reduction process [12,34,35]. More specifically, Arapov et al [12], Secor et al [34], and Del et al [35] enhanced graphene ink films to sheet resistances of 1.4 Ω/cm, 21.4 Ω/cm, and 30 kΩ/cm, respectively.…”

Graphene ink is a commercialized product in the graphene industry with promising potential application in electronic device design. However, the limitation of the graphene ink is its low electronic performance due to the ink preparation protocol. In this work, we proposed a simple post-treatment of graphene ink coating via electrochemical oxidation. The electronic conductivity of the graphene ink coating was enhanced as expected after the treatment. The proposed electrochemical oxidation treatment also exposes the defects of graphene and triggered an electrocatalytic reaction during the sensing of paracetamol (PA). The overpotential of redox is much lower than conventional PA redox potential, which is favorable for avoiding the interference species. Under optimum conditions, the graphene ink-based electrochemical sensor could linearly detect PA from 10 to 500 micro molar (µM), with a limit of detection of 2.7 µM.
