Special Issue Information

Dear Colleagues,

Carbon nanomaterials have revolutionized the field of materials science, and their multifunctional applications continue to expand. From the discovery of graphene's remarkable properties to the development of novel carbon nanotubes and other carbon-based structures, these materials have opened up new possibilities for various industries. This Special Issue, titled "Carbon Nanomaterials for Multifunctional Applications", aims to explore the latest advances in harnessing the unique properties of carbon nanomaterials for diverse applications. Carbon nanomaterials, such as graphene, carbon nanotubes, and fullerenes, exhibit exceptional properties, including high mechanical strength, electrical conductivity, thermal stability, and a large surface area. These attributes make them invaluable for a wide range of applications, from electronics and energy storage to aerospace and biomedical devices.

We invite researchers to contribute their original research articles, communications, and reviews to this Special Issue. Topics of interest include, but are not limited to:

  1. Novel Fabrication Techniques: Exploring innovative methods for the synthesis and production of carbon nanomaterials, pushing the boundaries of what is possible in terms of structure, purity, and scalability.
  2. Design of Multifunctional Materials: Investigating the design and development of advanced materials that incorporate carbon nanomaterials to achieve multifunctionality. This may include flexible composites, coatings, and hybrids with tailored properties.
  3. Advanced Characterization: Presenting cutting-edge techniques and tools for characterizing the microstructure and properties of carbon nanomaterials, shedding light on their behavior in various environments.
  4. Applications in Emerging Fields: Highlighting the use of carbon nanomaterials in exciting and emerging fields, such as nanoelectronics, sensor technology, energy conversion and storage, catalysis, and more.
  5. Carbon Nanomaterials for Environmental Solutions: Exploring how carbon nanomaterials can address environmental challenges, such as gas adsorption and separation, water purification, and sustainable energy generation.
  6. Safety and Toxicology: Discussing the safety and potential toxicological concerns associated with the use of carbon nanomaterials, along with strategies for responsible research and application.

Abstract
Polypyrrole (PPy)-capped silver nanowire (Ag NW) nanomaterials (core–shell rod-shaped Ag NW@PPy) were synthesized using a one-port suspension polymerization technique. The thickness of the PPy layer on the 50 nm thickness/15 μm length Ag NW was effectively controlled to 10, 40, 50, and 60 [...] Read more.
Polypyrrole (PPy)-capped silver nanowire (Ag NW) nanomaterials (core–shell rod-shaped Ag NW@PPy) were synthesized using a one-port suspension polymerization technique. The thickness of the PPy layer on the 50 nm thickness/15 μm length Ag NW was effectively controlled to 10, 40, 50, and 60 nm. Thin films cast from one-dimensional conductive Ag NW@PPy formed a three-dimensional (3D) conductive porous network structure and provided excellent electrochemical performance. The 3D Ag NW@PPy network can significantly reduce the internal resistance of the electrode and maintain structural stability. As a result, a high specific capacitance of 625 F/g at a scan rate of 1 mV/s was obtained from the 3D porous Ag NW@PPy composite film. The cycling performance over a long period exceeding 10,000 cycles was also evaluated. We expect that our core–shell-structured Ag NW@PPy composites and their 3D porous structure network films can be applied as electrochemical materials for the design and manufacturing of supercapacitors and other energy storage devices.

Graphene shows great potential in developing the next generation of electronic devices. However, the real implementation of graphene-based electronic devices needs to be compatible with existing silicon-based nanofabrication processes. Characterizing the properties of the graphene/silicon interface rapidly and non-invasively is crucial for this endeavor. In this study, we employ terahertz emission spectroscopy and microscopy (TES/LTEM) to evaluate large-scale chemical vapor deposition (CVD) monolayer graphene transferred onto silicon wafers, aiming to assess the dynamic electronic properties of graphene and perform large-scale graphene mapping. By comparing THz emission properties from monolayer graphene on different types of silicon substrates, including those treated with buffered oxide etches, we discern the influence of native oxide layers and surface dipoles on graphene. Finally, the mechanism of THz emission from the graphene/silicon heterojunction is discussed, and the large-scale mapping of monolayer graphene on silicon is achieved successfully. These results demonstrate the efficacy of TES/LTEM for graphene characterization in the modern graphene-based semiconductor industry. Full article
