Special Issue Information

Dear Colleagues,

Carbon nanotubes (CNTs), with their unique cylindrical structures and diverse exceptional properties, have attracted extensive attention over the past three decades. Research and applications have advanced significantly across various fields. Recently, with the rapid development of artificial intelligence (AI) techniques, the integration of nanoscience and AI has paved the way for innovative approaches to CNT synthesis, optimizing parameters with unprecedented precision and efficiency. From controlled growth mechanisms to tailored structural design, these advancements not only propel the field forward but also open avenues for the unparalleled customization of CNT properties.

This Special Issue of Nanomaterials will explore several key themes, incorporating both traditional and AI-enhanced modern research methodologies, including but not limited to scalable and sustainable methods for CNT synthesis, investigations into structural properties, and the transformative impact of CNTs across diverse fields such as nanoelectronics, energy storage, composite reinforcement, and biomedical applications. The objective is to capture the interest of both academic and industrial researchers, fostering an enhanced understanding of CNTs while also introducing innovative ideas to shape future applications and technologies. Researchers are encouraged to contribute original research articles or review articles addressing the current state of advancements in the CNT field.

The affinity between carbon nanotubes (CNTs) and organic compounds is of substantial importance since it strongly relates to the dispersibility of CNTs in those compounds. Several affinity evaluation methods have been developed so far, and the concept of the Hansen solubility parameter is a representative method widely used in the field of nanocarbon materials. Here, we demonstrate that CNT-loaded silica columns can effectively assess the affinity of organic compounds for CNT surface by exploiting the chromatographic retention time as a criterion. Obtained trends of the affinity of organic compounds for CNT were compared to those based on Hansen solubility parameter distance values. Most organic compounds showed similar trends, but one exceptional compound was observed. Simple CNT dispersion tests were conducted with these organic compounds to demonstrate the advantage of the chromatographic assessment. Further, we conducted comparison experiments using a pyrene-functionalized column and other CNT-loaded columns to elucidate the characteristics of each CNT column. The chromatographic approaches using CNT columns would be beneficial for realizing CNT suspensions with improved CNT dispersibility. Full article

Achieving the thermal conductivity required for efficient heat management in semiconductors and other devices requires the integration of thermally conductive ceramic fillers at concentrations of 60 vol% or higher. However, an increased filler content often negatively affects the mechanical properties of the composite matrix, limiting its practical applicability. To address this issue, in this paper, we present a new strategy to reduce the required ceramic filler content: the use of a thermally conductive ceramic composite filler with carbon nanotubes (CNTs) grown on aluminum nitride (AlN). We combined catalyst coating technology with vacuum filtration to ensure that the catalyst was uniformly applied to micrometer-sized AlN particles, followed by the efficient and uniform synthesis of CNTs using a water-assisted process in a vertical furnace. By carefully controlling the number of vacuum filtration cycles and the growth time of the CNTs, we achieved precise control over the number and length of the CNT layers, thereby adjusting the properties of the composite to the intended specifications. When AlN/CNT hybrid fillers are incorporated into silicone rubber, while maintaining the mechanical properties of rubber, the thermal diffusivity achieved at reduced filler levels exceeds that of composites using AlN-only or simultaneous AlN and CNTs formulations. This demonstrates the critical influence of CNTs on AlN surfaces. Our study represents a significant advancement in the design of thermally conductive materials, with potential implications for a wide range of applications. Full article
