“…The longitudinal GF was calculated from Eq. (7). Interestingly, the estimated GF of the monolayer graphene strain gauge at 25 °C is about 255, which is higher than the reviewed values for monolayer graphene, (9)(10)(11)(12)36) and opens a new era for piezoresistive strain gauges with very high sensitivity, while the measured GF of the multilayer graphene strain gauge at the same temperature is about 104.…”

“…Recently, graphene has been presented as a potential piezoresistive material that can withstand a large strain and is stable up to a temperature of 700 °C, aside from having a very high carrier mobility. (3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18) Moreover, graphene is compatible with the wafer level owing to its two-dimensional architecture, suggesting that the material could be a promising template for novel microfabrication processes.…”

“…Recently, we have reported the first production of a defective laser-reduced graphene oxide film with a multilayer structure for the microfabrication of a strain gauge sensor using a carbon dioxide (CO 2 ) laser beam to simultaneously reduce and pattern a drop-casted and pre-dried graphene oxide film dispersed over a flexible polyethylene terephthalate (PET) substrate. (6)(7)(8) A commercially available laser printing machine was adopted, enabling reliable, high-throughput production without special preparation or adjustment while using large patterning areas and a thick film. This further lowers the production cost.…”

Monolayer and multilayer graphene films have been grown on a Cu substrate by chemical vapor deposition (CVD) and then transferred onto a SiO 2 /Si substrate using polymethyl methacrylate (PMMA) to fabricate an ultrasensitive graphene-based strain gauge sensor. The graphene films were patterned using a CO 2 laser beam. The sensitivity and temperature dependence of the gauge factor (GF) of the fabricated sensors were examined at different applied strains and operating temperatures up to 0.05% and 75 °C, respectively. The fabricated gauges based on monolayer and multilayer graphene films show stable GFs of 255 and 104 within the applied temperature range, respectively. The patterning technique provides an interesting, lowcost, fast, and high-throughput process to realize scalable microfabrication for highly sensitive strain sensors with good temperature stability based on graphene piezoresistivity. A theoretical simulation of the GF of monolayer graphene has also been carried out on the basis of firstprinciples calculation. Simulation results follow the measured GFs in our experiment and other references. *. The data are averaged for all angles (0° ≤ θ < 360°).

“…GO film in TEM imaging presented some darker regions (see Figure 3c), related to the stacking of some GO layers 43 . FTIR analysis confirmed peaks ascribed to the function groups of GO at 1077.28 cm −1 , which is attributed to the C–O bond, 44,45 whereas the peak at 1633.76 cm −1 is attributed to the C=C bond. The C = O bonds of the carboxylic acid group were detected at the peak 1721.53 cm −1 , whereas the peaks in the range of 2933.83–3756 cm −1 are associated with the water function groups presenting O–H bonds (see Figure 4a).…”

The display of papyrus and paper (as cellulosic materials) in the Egyptian museums is always critical due to the traditional placement of display of sensitive materials between two plates of glass, acrylic, or other types of glazing materials. The sensitivity of the glazing materials to abrasion, ultraviolet rays, dust adhesion, and high light reflectivity are considered concerning issues to conservators, curators, and visitors. In this paper, thin protective coatings of graphene oxide (GO) were synthesized by modified Hummers' method and deposited on selected museums' glazing materials (glass and acrylic) using spin coating. Multi‐analytical techniques were employed to assess the applicability of GO‐coated glazing including scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), Raman spectroscopy (RS), Fourier transform infrared spectroscopy (FTIR), microhardness testing, NIR VIS, and UV spectrophotometer and static potential measurements. The results showed that the glass glazing hardness was increased by ~10% due to the deposition of the GO coating. Moreover, according to glazing type, the reflectance values of the GO‐coated glazing samples, compared with the uncoated samples, confirmed that the thin film of GO improved the UV rays blocking. As is evident in the GO‐coated glass where approximately 27% of UV rays have been blocked, likewise, 19% of UV rays were blocked in GO‐coated acrylic (TRU VUE). Considering VIS and NIR reflection spectra of GO‐coated plexiglass, a higher reflectance is presented by 29%. Furthermore, the static potential measurements showed an energy decline in GO‐coated glazing compared with the uncoated samples.

“…As a result, GNPs are considered a game changer for numerous sensing application. Recently, GNPs have aroused tremendous interest for various sensing applications (Gamil et al , 2014a; Gamil et al , 2014c; Sayed et al , 2016; Sayed et al , 2015). However, there are only few reports on using GNPs as a temperature-based resistance sensor.…”

Purpose This study aims to present an efficient and reliable graphene nanoplatelets (GNPs)-based temperature sensor. Design/methodology/approach A high-quality dispersion of GNPs was dropped by casting method on platinum electrodes deposited on a polyethylene terephthalate (PET) substrate. The GNPs were characterized by scanning electron microscope, Raman spectroscopy and X-ray diffraction spectra to ensure its purity and quality. The temperature sensing behavior of the fabricated sensor was examined by subjecting it to different temperatures, range from room temperature (RT) to 150 °C. Findings Excellent resistance linearity with temperature change was achieved. Temperature coefficient of resistance of the fabricated sensor was calculated as 1.4 × 10–3°C. The sensor also showed excellent repeatability and stability for the measured temperature range. Good response and recovery times were evaluated at all the measured temperatures. With measuring the sensor response, the ambient temperature can be determined. Originality/value The present work presents a new simply and low cost fabricated temperature sensor based on GNPs working at a wide temperature range.
