Special Issue Information

Dear Colleagues,

The application of carbon nanomaterials (carbon nanotubes, carbon nanofibers, graphene, graphene oxide, porous carbons, and diamond-like carbons, etc.) and related materials for chemical sensing is important due to their unique properties and ability to modify the characteristics of detection of various substances.

This Special Issue will focus on understanding the properties of carbon nanomaterials and their impact on various sensors. In particular, the characteristics of sensors, such as response, sensitivity, selectivity, operating temperature, operating relative humidity, and their interconnection with the structure, surface area, and the chemistry of the surface of active materials are of interest. The modification, functionalization, and activation of the surface of carbon nanomaterials in order to improve the response and other characteristics is also an urgent problem considered in the Special Issue.

In this Special Issue, we invite researchers and authors to submit review articles and original research on carbon nanomaterials and related materials for sensing applications. Potential topics include, but are not limited to, the following:

  • Carbon nanomaterials and related materials for gas sensors;
  • Carbon nanomaterials and related materials for biosensors;
  • Carbon nanomaterials and related materials for electrochemical sensors;
  • Functionalization of carbon nanomaterials for sensing applications;
  • Hybrid materials based on carbon nanomaterials for gas sensors and biosensors;
  • Doped carbon nanomaterials for chemical sensing;
  • Operating conditions of gas sensors based on carbon nanomaterials;
  • Quantum chemical simulation of adsorption processes in hybrid materials.

The use of graphene and other carbon nanoparticles is now of interest for developing chemical (gas and compounds detectors) and physical sensors. In this work, a graphene nanoplatelet (GNP)-PDMS sensor is proposed. More specifically, its strain-sensing capabilities under consecutive cycles as well as the crack propagation mechanisms are widely analyzed. First, an analysis of the electrical properties shows that the increase of the GNP content leads, as expected, to an increase of the electrical conductivity, ranging from values around 10−3 to 1 S/m for 5 and 11 wt.% samples. The analysis of crack propagation monitoring capabilities shows an exceptional sensitivity of the proposed flexible sensors, with a highly exponential behavior of the electrical resistance due to the prevalent breakage of the electrical pathways as crack propagation occurs. Furthermore, the analysis of the electrical response under cyclic load proves a very high robustness, with a similar response when comparing different cycles and an electrical sensitivity that increases when decreasing the GNP content (from 15–25 to 25–50 at 7 and 11 wt.% GNP content, respectively), a fact that is explained by the prevalence of tunneling mechanisms at low contents. Finally, a proof-of-concept of human motion monitoring by the detection of neck, wrist and facial movements is successfully achieved, indicating the high applicability of the proposed sensors.
