2 wrz 2020 · Apart from the foremost use in fiber-reinforced composites, carbon fibers are used in electrode/microelectrodes (i.e., a single carbon fiber), flexible heating applications, whenever a low wear friction on the contact interface is required (e.g., brush contact).
15 wrz 2020 · To address this problem, we report here the treatment of microstructured carbon fiber (CF) via a surface engineering strategy, which adopts controllable oxygen (O) functional groups on the CF surface with both highly redox-active sites and fast electron/ion transport.
15 kwi 2021 · This process can tailor the O-species configuration for engineering edge-O active sites, and meanwhile re-establish a π-π conjugated system on the plane of carbon skeleton. Such a design endows the edge-O functionalized carbon fiber (EOCF) with abundant active sites and good electrical conductivity.
Carbon nanotube wiring may be extremely light and mechanically stronger and more efficient in transferring high frequency signals than any conventional conducting material, being cost-effective simultaneously. However, transfer of the unique properties of individual CNTs to the macro-scale proves to be quite challenging. This Feature Article ...
15 lip 2024 · Therefore, ACFs are a promising catalyst for the oxidation of H 2 S at room temperature. In this work, a series of Na 2 CO 3 loaded ACF catalysts were prepared and tested for H 2 S catalytic oxidation at room temperature. Particularly, the active oxygen species of the reaction were deeply explored.
1 gru 2016 · Relationships between carbon fiber microstructure and material performance is undertaken in order to assess the current status of the mechanical, thermal, and electrical properties of commercially available PAN and pitch based carbon fibers, as well as recently developed experimental carbon fibers.
5 cze 2023 · Abundant oxygen-containing functional groups and a certain number of GQDs can increase the surface activity of carbon fibers and provide more active reaction sites in the electrochemical process, which improves some pseudocapacitance properties and the electrochemical properties of carbon fibers.
