“…Shahzad et al [17] synthesized a kind of fluorinedoped reduced graphene oxide which showed higher electrical conductivity of 750 S m −1 than that of undoped rGO which was 195 S m −1 , and EMI was simultaneously enhanced. RGO was deposited on a screen-printed gold electrode by electrochemical method with subsequent modification of carbon-gold nanocomposites to prepare gas sensor which possessed good sensitivity and linearity [18]. Single Co atoms (≈ 5.3%) were anchored on graphene oxide to solve the problem of the decomposition of insulating Li 2 CO 3 on the cathode, and it exhibited high sustained discharge capability [19].…”

Interfacial bonding between the fibers and matrix plays a large role in mechanical properties of composites. In this paper, poly(oxypropylene) diamines (D400) and graphene oxide (GO) nanoparticles were grafted on the desized 3D multi axial warp knitted (MWK) glass fiber (GF) fabrics. The surface morphology and functional groups of modified glass fibers were characterized by scanning electron microscopy (SEM) and fourier transform infrared spectra (FT-IR). Out-of-plane compression properties and the failure mechanisms of composites at different temperature were tested and analyzed. The results revealed that GO nanoparticles were successfully grafted on fibers under the synergistic effect of D400. In addition, D400-GO-grafted composite possessed the highest mechanical properties than desized composite and GO-grafted composite. Their strength and modulus were improved by 10.16%, 10.06%, 8.92%, 8.75%, 7.76% and 40.38%, 32.74%, 29.85%, 26.98%, 25.16% compared to those of desized composites at 30∘C, 60∘C, 90∘C, 120∘C, 150∘C, respectively. The damage to D400-GO-grafted composite was yarns fracture accompanied with fibers breakage, matrix cracking, interface debonding. At higher temperature, interlayer slipping with matrix plasticization was the main failure mode.

Over the past decade, organic semiconductors and renewable resources have aroused great interest in basic research and practical applications. Composites based on organic materials and materials of biological origin, if not all bio-based, are potentially abundant and partly biodegradable. These materials have demonstrated advantages making them ideally suited for gas-sensing applications. Herein, we present different detection principles of gas sensing, such as electrochemical, resistive, capacitive, and acoustic sensors. Besides, we describe sensing properties and suitable materials to enhance the selectivity, sensitivity and response/recovery time of gas sensors. In addition, an overview of different forms of materials based on renewable resources and inorganic/organic semiconductors, as well as the development of different types of sensors are discussed. Finally, challenges and future directions are examined in order to develop a low-cost microscale sensing technology using composite materials based on renewable resources. We anticipate that chemical engineering, computer science, machine learning and embedded systems can contribute to the development of new sensing materials.

“…In 2019, Wan et al [ 171 ] synthesised a novel and highly sensitive rGO-based electrochemical gas sensor with carbon–gold nanocomposites (CGNs) by glucose carbonisation and deposition of AuNPs via the hydrothermal procedure ( Figure 4 ). This rGO–CGN customised gas sensor exhibited considerably improved existing reactions during oxygen sensing.…”

The environmental crisis, due to the rapid growth of the world population and globalisation, is a serious concern of this century. Nanoscience and nanotechnology play an important role in addressing a wide range of environmental issues with innovative and successful solutions. Identification and control of emerging chemical contaminants have received substantial interest in recent years. As a result, there is a need for reliable and rapid analytical tools capable of performing sample analysis with high sensitivity, broad selectivity, desired stability, and minimal sample handling for the detection, degradation, and removal of hazardous contaminants. In this review, various gold–carbon nanocomposites-based sensors/biosensors that have been developed thus far are explored. The electrochemical platforms, synthesis, diverse applications, and effective monitoring of environmental pollutants are investigated comparatively.
