“…The preparation methods of carbon nanotubes basically use energy to decompose the carbon source into atomic or ionic forms, and then condense into a onedimensional structure of carbon. At present, three most popular fabrication methods have been utilized to obtain large-scale carbon nanotubes, which are, Arc Discharge method (Chhowalla and Unalan, 2011), Laser Ablation method (Danilov et al, 2014) and Chemical Vapor Deposition (CVD) method (Kumar and Ando, 2010). CNT prepared by different methods significantly vary with respect to their structure and properties.…”

Energy storage is a key requirement for the emerging wearable technologies. Recent progress in this direction includes the development of fiber based batteries and capacitors and even some examples of such fibers incorporated into prototype textiles. Herein we discuss the advantages of using the wet-spinning process to create nanostructured carbon based materials as wearable energy storage. The ability to control the physical, mechanical, electrical, and electrochemical properties of carbon nanotube based fibers holds great promise to develop smart polymeric structure as an energy storing materials including fibers and textiles. This is the first comprehensive review to discuss effect of nanostructured energy materials on the electrochemical properties of carbon nanotube based fibers which covers the various compositions, spinning and fabrication conditions on the performance of wearable energy storage.

“…At the next stage, the as‐fabricated SWCNT film stripes were micro‐sliced into two separate parts to perform device anode and cathode, respectively (Figure 1b). Noticeably, it was done with femtosecond laser (pulse duration 200 fs and wavelength λ = 1040 nm) at low pulse repetition rate to achieve average intensity below the threshold for PEN melting, while at the same time providing fluence level in each pulse around 0.5 J cm −2 which is sufficient for SWCNT film ablation [ 42 ] and being typical regime for carbon‐based nanomaterials removal. [ 43 ] It is worth noting, that this principle could be applied for SWCNT film ablation on any transparent polymer substrate.…”

Metal–halide perovskites have recently shown tremendous progress in flexible photodetector applications owing to their great optical and electronic properties. However, apart from charge generating material, the high performance device requires a reasonable choice of electrodes for efficient carrier management as well. For example, the widespread use of gold and silver electrodes often results in perovskite device degradation while being expensive. Here, low‐cost and chemically inert single‐walled carbon nanotube (SWCNT) thin films are employed as electrodes to create highly responsive and flexible photodetector based on cesium lead tribromide (CsPbBr3) microcrystals. Direct growth of the perovskite on SWCNT forms excellent contact between the components leading to the state‐of‐the‐art responsivity for flexible perovskite photodetectors 1321 A W−1 at 5 V and under illumination intensity 1 mW cm−2 at 505 nm wavelength. The advanced properties of SWCNT films realized on a flexible substrate allow for robust operation over 104 cycles of device bending along with all parameters stability at ambient conditions for at least 1.5 months. The proposed design reveals the potential of SWCNT thin film electrodes for high performance perovskite flexible devices.

“…Danilov and coworkers ablated dense SWCNT based bulk materials at two wavelengths, with single and multi-shot laser exposure. They reported less damage with shallow material removal, and high damage demonstrated by micro craters by single and multi-shot laser irradiation, respectively [27]. On the other hand, Arutyunyan et al [28] studied the selective removal of a specific category of SWCNT thin film by resonant ablation through femtosecond pulses.…”

Processing of Single-Walled Carbon Nanotubes with Femtosecond Laser Pulses

There are continued efforts to process and join single wall carbon nanotubes (SWCNTs) in order to exploit their exceptional functional properties for real-world applications. In this work, we report experimental observations of femtosecond laser irradiation on SWCNTs, in order to process and join them through an efficient and cost-effective technique. The nanotubes were deagglomerated in ethanol by an ultrasonicator and thin slurries of SWCNTs were spread evenly on glass substrates. A laser micromachining workstation for laboratory FemtoLAB (workshop of photonics) has been employed to irradiate the different SWCNTs film samples. The effect of laser parameters, such as pulse wavelength, laser power, etc., were systematically tuned to see the possibility of joining the SWCNTs ropes. Several experiments have been performed to optimize the parameters on different samples of SWCNTs. In general, the nanotubes were mostly damaged by the infrared (1st harmonics femtosecond laser) irradiation on the focal plane. However, the less damaging effect was observed for second harmonics (green wavelength) irradiation. The results suggest some joining of nanotubes along the sides of the focus plane, as well as on the center at the brink of nanotubes. The joining is considered to be established within the region of the high field intensity of the exposed femtosecond laser beam.
