J Raman Spectroscopy

Graphene oxide (GO) enhanced textiles were studied using Raman spectroscopy. Compared with regular textiles, GO‐enhanced textiles show GO's signature D and G peaks at 1,350 and 1,580 cm−1; they also show GO's harmonics peaks at 2,690 and 2,925 cm−1. The intensity of GO's signature peaks has linear correlation with GO's percentage in weight. A principal component analysis (PCA) and support vector machine (SVM) model are used to classify textile samples with 98.75% accuracy.

“…This research provided a low cost, practical method for utilizing DIW for micro-and nanoscale devices. Additional studies have used DIW printing technologies for all-solid-state graphene-based in-plane MSCs, [175] highly transparent and flexible graphene MSCs, [176] rGO-coated textile fabrics as electrodes in supercapacitors, [177] and MSCs with interdigitated graphene patterns. [178] Ujjain et al used DIW to print a CNT electrode for supercapacitors.…”

Superior electrochemical performance, structural stability, facile integration, and versatility are desirable features of electrochemical energy storage devices. The increasing need for high‐power, high‐energy devices has prompted the investigation of manufacturing technologies that can produce structured battery and supercapacitor electrodes with optimized charge transport. While conventional electrode production techniques are becoming increasingly obsolete and incompatible with technological developments such as wearables and flexible electronics, additive manufacturing (AM) has emerged as one of several state‐of‐the‐art tools to produce 3D‐structured electrodes with morphology control, high yield, and scalability. Herein, a comprehensive review of the major AM technologies and most recent literature about designing and manufacturing electrode materials for batteries and supercapacitors is presented. A thorough discussion of research opportunities and challenges in this promising field is also presented to introduce the potential and importance of AM to current developments involving electrode materials.

“…A platinum-coated atomic force microscope tip has been used to induce the locally catalytic reduction of graphene oxide, enabling nanoribbons to be produced with widths of 20-80 nm [30]. Recently, an original method based on reactive inkjet printing was proposed for the production of reduced graphene oxide on textile substrate elements, which were then applied in a supercapacitor [31].…”

“…Summarizing the literature and issues discussed above, two conclusions can be made. First, a variety of methods and substrates can be used for graphene synthesis and to support the graphene layer: the chemical vapor deposition of graphene on various materials, such as metallic foil (Cu, Ni) [16,17], SiC [23], SiO 2 /Si [18,20,22], or on glass [19]; transferring CVD graphene onto SiO 2 /Si [21,24,25,52,54], PMMA [26], or on Si/SiN [27]; laser-induced chemical vapor deposition [34,35]; graphene ink coating on glass [57,58]; direct laser synthesis [37,38]; spin-coating a GO solution onto glass [41][42][43]45], polymer [48,49], or on sapphire [30]; and reactive inkjet printing of GO on textile surfaces [31]. Second, different types of lasers can be used for graphene patterning, including nano-, pico-, and femtosecond pulsed lasers generating beams with wavelengths from UV to IR.…”

Sensors

This paper describes a method for patterning the graphene layer and gold electrodes on a ceramic substrate using a Nd:YAG nanosecond fiber laser. The technique enables the processing of both layers and trimming of the sensor parameters. The main aim was to develop a technique for the effective and efficient shaping of both the sensory layer and the metallic electrodes. The laser shaping method is characterized by high speed and very good shape mapping, regardless of the complexity of the processing. Importantly, the technique enables the simultaneous shaping of both the graphene layer and Au electrodes in a direct process that does not require a complex and expensive masking process, and without damaging the ceramic substrate. Our results confirmed the effectiveness of the developed laser technology for shaping a graphene layer and Au electrodes. The ceramic substrate can be used in the construction of various types of sensors operating in a wide temperature range, especially the cryogenic range.
