“…Thus, the CNTs can only grow thicker after this initial growth stage. Thickening of the CNTs, which process is associated with an increase in the number of graphitic walls, can proceed through the traditional CSDP growth mechanism described above, as well as through gas phase-induced thickening [19]. These ''graphitic carbonaceous impurities'' as reported by Yasuda et al tend to nucleate at defects on the CNT walls [14].…”

“…CNTA papers 18 were prepared simply by rolling and pressing 1.2 mm-thick CNT arrays grown on whole silicon wafers ( Figure S1 ). In order to minimize the decomposition of the LiPF 6 organic electrolyte commonly used in LIB at high potentials, an electrolyte comprising of LiF and a fluoride-anion receptor of tris(pentafluorophenyl)borane (TPFPB) in the organic solvents was formulated and demonstrated excellent electrochemical stability over 4.5 V vs. Li/Li + at 22°C and 70°C ( Figure S2 in supplementary materials ).…”

“…Millimeter-thick multi-walled CNT arrays were grown on the whole 4- or 6-inch silicon wafers, following water-assisted chemical vapor deposition (WACVD) method reported elsewhere 18 . The as-grown1.2 ± 0.2 mm-thick CNT arrays on the silicon wafers were rolled and pressed to CNT array (CNTA) papers.…”

High performance rechargeable batteries are urgently demanded for future energy storage systems. Here, we adopted a lithium-carbon battery configuration. Instead of using carbon materials as the surface provider for lithium-ion adsorption and desorption, we realized induced fluorination of carbon nanotube array (CNTA) paper cathodes, with the source of fluoride ions from electrolytes, by an in-situ electrochemical induction process. The induced fluorination of CNTA papers activated the reversible fluorination/defluorination reactions and lithium-ion storage/release at the CNTA paper cathodes, resulting in a dual-storage mechanism. The rechargeable battery with this dual-storage mechanism demonstrated a maximum discharging capacity of 2174 mAh gcarbon−1 and a specific energy of 4113 Wh kgcarbon−1 with good cycling performance.

Introduction It is 23 years since carbon allotrope known as carbon nanotubes (CNT) was discovered by Iijima, who described them as “rolled graphite sheets inserted into each other”. Since then, CNTs have been studied in nanoelectronic devices. However, CNTs also possess the versatility to act as drug- and gene-delivery vehicles. Areas covered This review covers the synthesis, purification and functionalization of CNTs. Arc discharge, laser ablation and chemical vapor deposition are the principle synthesis methods. Non-covalent functionalization relies on attachment of biomolecules by coating the CNT with surfactants, synthetic polymers and biopolymers. Covalent functionalization often involves the initial introduction of carboxylic acids or amine groups, diazonium addition, 1,3-dipolar cycloaddition or reductive alkylation. The aim is to produce functional groups to attach the active cargo. Expert opinion In this review, the feasibility of CNT being used as a drug-delivery vehicle is explored. The molecular composition of CNT is extremely hydrophobic and highly aggregation-prone. Therefore, most of the efforts towards drug delivery has centered on chemical functionalization, which is usually divided in two categories; non-covalent and covalent. The biomedical applications of CNT are growing apace, and new drug-delivery technologies play a major role in these efforts.
