“…Therefore, in the past decades, much efforts [7,43,48] have been devoted to improve the performance of the SWCNT-TCFs. Specifically, sulfur-assisted SWCNTs grown by the FC-CVD technique have been extensively employed to fabricate high-performance SWCNT-TCFs [48,49]. Unfortunately, in the literature the concrete impact of sulfur addition in enhancing the conductivity of the SWCNT films is ambiguous.…”

“…Since, in most of the cases without sulfur, no information about SWCNT yield, morphology, structure and also the performance of the SWCNTs based films has been provided [48,49]. Consequently, the real out-turn of the sulfur addition on yield, morphology and structure of SWCNTs is ambiguous.…”

“…On the contrary, our results showed that spark-produced Ni has poor catalytic activity towards the synthesis of SWCNTs in the FC-CVD method. Also, Fe is widely explored catalyst for the synthesis of SWCNTs in the FC-CVD method [48,49]. Therefore, we synthesized bimetallic catalyst particles of Co with Fe and Ni which have never been studied in the FC-CVD growth of SWCNTs.…”

“…It is important to differentiate the metallic SWNTs (m‐SWNTs) from the semiconducting SWNTs (s‐SWNTs) as SWNTs can have mixtures of m‐SWNTs and s‐SWNTs . The Schottky barriers between m‐SWNTs and s‐SWNTs have to be considered when investigating the doping effect …”

The charge interaction and corresponding doping effect between single‐walled carbon nanotubes (SWNTs) and various fullerene derivatives, namely, C60, phenyl‐C61‐butyric acid methyl ester (PC61BM), methano‐indenefullerene (MIF), 1′,1″,4′,4″‐tetrahydrodi[1,4]methanonaphthaleno[5,6]fullerene (ICBA), 1,4‐bis(dimethylphenylsilylmethyl)[60]fullerene (SIMEF‐1), and dimethyl(orthoanisyl) silylmethyl(dimethylphenylsilylmethyl)[60]fullerene (SIMEF‐2), are investigated. A variety of analytical techniques, including field‐effect transistors (FETs) made of horizontally aligned arrays of SWNTs, is used as a means of investigation. Data from different measurements have to be used to obtain a concrete evaluation for the fullerene‐applied SWNTs. The data collectively points toward the conclusion that fullerenes with high molecular orbital energy levels, namely, MIF, SIMEF‐1, SIMEF‐2, and PC61BM, induce p‐type doping, while fullerenes with low molecular orbital energy levels, namely, ICBA and C60, induce n‐type doping on the carbon nanotubes. Nevertheless, the SWNTs retained p‐type characteristics because n‐doping induced by the fullerenes are weak compared to the p‐doping of the water and oxygen on carbon nanotubes. This means that fullerene derivatives have the ability to fine‐tune the energy levels of carbon nanotubes, which can play a crucial role in carbon nanotube‐based electronics, such as solar cells, light‐emitting devices, and FETs.

Solid and flexible electrochromic (EC) devices require a delicate design of every component to meet the stringent requirements for transparency, flexibility, and deformation stability. However, the electrode technology in flexible EC devices stagnates, wherein brittle indium tin oxide (ITO) is the primary material. Meanwhile, the inflexibility of metal oxide usually used in an active layer and the leakage issue of liquid electrolyte further negatively affect EC device performance and lifetime. Herein, a novel and fully ITO-free flexible organic EC device is developed by using Ag-Au core-shell nanowire (Ag-Au NW) networks, EC polymer and LiBF 4 /propylene carbonate/ poly(methyl methacrylate) as electrodes, active layer, and solid electrolyte, respectively. The Ag-Au NW electrode integrated with a conjugated EC polymer together display excellent stability in harsh environments due to the tight encapsulation by the Au shell, and high area capacitance of 3.0 mF cm −2 and specific capacitance of 23.2 F g −1 at current density of 0.5 mA cm −2 . The device shows high EC performance with reversible transmittance modulation in the visible region (40.2% at 550 nm) and near-infrared region (−68.2% at 1600 nm). Moreover, the device presents excellent flexibility (>1000 bending cycles at the bending radius of 5 mm) and fast switching time (5.9 s).
