“…We have made clear that it was possible to control the size and density of the obtained nanopores by adjusting the nc-Cu/C sputtering conditions. We also showed that the electrical conductivity of the obtained np-C was dependent on its microstructure and morphology [6]. Nevertheless, our study was limited to the synthesis of nc-Cu/C films deposited at low temperature (i.e.…”

“…Recently, our group has developed a two-step approach to synthesize np-C thin films [6]. The process consists in the deposition of copper/carbon nanocomposite (nc-Cu/C) thin films followed by a selective chemical etching of the copper phase in order to obtain np-C.…”

“…Different systems have been explored, including Ni [13], Fe [14], Cu [15,16], Au and Pt [14]. Our nc-Cu/C thin films were synthesized by co-sputtering of a graphite and a copper target in co-focal configuration at low temperature [6]. We have made clear that it was possible to control the size and density of the obtained nanopores by adjusting the nc-Cu/C sputtering conditions.…”

, et al.. Effect of temperature on the synthesis of nanoporous carbon from copper/carbon thin films to nanoporous carbon for sensing applications. Thin Solid Films, Elsevier, 2017Elsevier, , 630, pp.59-65. <10.1016Elsevier, /j.tsf.2016.014>. A C C E P T E D M A N U S C R I P T ACCEPTED MANUSCRIPT AbstractOver the last few years, a broad panel of carbon materials was proposed for sensing applications. Among these materials, nanoporous carbon (np-C) is of particular interest due to its high specific surface area and low fabrication cost. In this contribution, the synthesis of np-C thin films using an approach combining the growth of copper/carbon nanocomposite thin films by co-sputtering followed by a selective wet etching of copper in nitric acid is studied.By adjusting the deposition conditions (e.g., powers applied to the sputtering targets, deposition temperature) of the nanocomposite thin films, it is shown that the pore size and the structure of the carbon skeleton can be modified. Furthermore, the possibility of integrating such nanoporous materials in field effect transistors for sensing application is also demonstrated.

“…Motivated by these promising properties, many efforts have been made to synthesize porous carbon materials, [15][16][17] of which dual templating combining soft and hard templates has become a promising method. Hierarchical porous materials synthesized by dual templating own high surface area, easy accessibility to active sites, and high mass transport and diffusion rate at the same time.…”

The hierarchically porous carbon fabrics with controlled conductivity and hydrophilicity have been fabricated by dual templating method of soft templates nested on hard templates. A non‐woven fabric coated with a solution of F127/resol has been carbonized for the synthesis of both macro‐porous structures of 10–15 µm in diameter having meso‐porous carbon structures of 4–6 nm, respectively. After carbonization treatment, not only conductivity is significantly improved, the hierarchically porous carbon also shows superhydrophilicity or water‐absorbing nature due to mild hydrophilic material and its dual scale roughness. The porous carbon becomes conductive with resistivity widely tuned from 5.4 × 103 Ωm to 3.1 × 10−3 Ωm by controlling the carbonization temperature. As the increased wettability for organic liquids could lead organic molecules deep into carbonized fabrics, the sensitivity of hierarchically porous carbon fabrics benefits the detection for methanol(CH3OH) or hydrogen peroxide (H2O2). This new design concept of hierarchically porous structures having the multi‐functionality of high wettability and conductivity can be highly effective for electroanalytical sensors.

Transparent electrodes (TEs) are pivotal components in many modern devices such as solar cells, light‐emitting diodes, touch screens, wearable electronic devices, smart windows, and transparent heaters. Recently, the high demand for flexibility and low cost in TEs requires a new class of transparent conductive materials (TCMs), serving as substitutes for the conventional indium tin oxide (ITO). So far, ITO has been the most used TCM despite its brittleness and high cost. Among the different emerging alternative materials to ITO, metallic nanomaterials have received much interest due to their remarkable optical‐electrical properties, low cost, ease of manufacturing, flexibility, and widespread applicability. These involve metal grids, thin oxide/metal/oxide multilayers, metal nanowire percolating networks, or nanocomposites based on metallic nanostructures. In this review, a comparison between TCMs based on metallic nanomaterials and other TCM technologies is discussed. Next, the different types of metal‐based TCMs developed so far and the fabrication technologies used are presented. Then, the challenges that these TCMs face toward integration in functional devices are discussed. Finally, the various fields in which metal‐based TCMs have been successfully applied, as well as emerging and potential applications, are summarized.
