Article Abstract
Carbon nanotube (CNT) sheets represent a novel implementation of CNTs that enable the tailoring of electrical and mechanical properties for applications in the automotive and aerospace industries. Small molecule functionalization and postprocessing techniques, such as irradiation with high-energy particles, are methods that can enhance the mechanical properties of CNTs. However, the effect that these modifications have on the electrical conduction mechanisms has not been extensively explored. By characterizing the mechanical and electrical properties of multiwalled carbon nanotube (MWCNT) sheets with different functional groups and irradiation doses, we can expand our insights into the extent of the trade-off that exists between mechanical strength and electrical conductivity for commercially available CNT sheets. Such insights allow for the optimization of design pathways for engineering applications that require a balance of material property enhancements.

Bisphenol A (BPA) is a persistent organic pollutant with toxic effects on human health and ecosystems. In this study, the performance of MWCNT-OH functionalized with iron nanoparticles (MWCNT-OH@Fe) using sugarcane bagasse extract as a reducing agent (green synthesis) was evaluated for BPA adsorption. The kinetics are fast, between 10 and 20 min in the range of concentrations evaluated and the resistance to external film diffusion (external film mass transfer) identified as the rate-limiting step of the process.

High-performance, low-cost electrocatalysts are essential for freshwater-independent seawater electrolysis. We design a SWCNT-supported (FeCoNiMnCr)O high-entropy spinel oxide by a hydrothermal method and air-firing, where the conductive network enhances charge transfer and active site exposure. The catalyst achieves 282 mV@10 mA cm with 100 h stability in alkaline seawater.

Effective removal of trace heavy metal ions from aqueous bodies is a pressing problem and requires significant improvement in the area of absorbent material in terms of removal efficiency and sustainability. We propose an efficient strategy to enhance the adsorption efficiency of carbon nanotubes (CNTs) by growing dendrimers on their surface. First, CNTs were pre-functionalized with maleic acid (MA) via Diels-Alder reaction in presence of a deep eutectic solvent under ultrasonication.

Uniform dispersion of carbon nanotubes in a polymer matrix is a prerequisite for high-performance nanotube-based composites. Here, we report an in situ polymerization route to synthesize a range of phenolic composites with high loading of single-wall carbon nanotubes (SWCNTs, >40 wt%) and continuously tunable viscoelasticity. SWCNTs can be directly and uniformly dispersed in cresols through noncovalent charge-transfer interactions without the need for surfactants, and further concentrated before in situ polymerization of the solvent molecules, yielding phenolic composites in the forms of conductive pastes, highly stretchy doughs, and hardened solids with high nanotube loading and much enhanced electrical conductivity (up to 2.

A sensitive electrochemical glucose biosensor using ZrO₂@CNTs nanocomposite was developed for real-time metabolism monitoring for athletes. The nanocomposite was prepared by a simple ultrasound-assisted technique, and the glucose oxidase (GOx) was covalently immobilized to improve the biorecognition ability. CNTs treated with acid served as a highly conductive framework, and ZrO₂ nanoparticles can provide structural stability and catalytic performance, thus showing synergistic enhancement of electron transfer kinetics and enzyme loading capacity.
