“…The first report was from Li et al, who studied the photothermal conversion property of Ti 3 C 2 T x and reported that the internal light-to-heat conversion efficiency of MXene, more specifically Ti 3 C 2 , was measured to be 100%. Also, they have reported that MXene materials possess higher electric conductivity than CNT and rGO materials, the two popular and effective photothermal materials in the literature. ,, This study indicated that the MXenes consistently exhibited higher light absorption than CNT in the entire wavelength range, as depicted in Figure b. In this work, a single wavelength laser illuminated the droplet of an aqueous solution containing Ti 3 C 2 T x .…”

MXenes are the new members in the family of two-dimensional (2D) layered materials composed of transitional metal carbides, nitrides, or carbonitrides. Among all other MXenes, Ti3C2T x MXene is the most studied one due to the exceptional properties that make it suitable for various applications, including optoelectronics. Ti3C2T x MXene can be fabricated and processed in a variety of scalable and cost-effective ways. MXenes are solution-processable materials that can be deposited by spin, spray, or dip coating, painting, or printing. They exhibit excellent optical transparency, high metallic conductivity, efficient photothermal conversion, plasmonic behavior, and tunability of the optical response over traditional 2D materials. These features have led to a fast evolution of this material with many explorations of its applications in the field of optoelectronics. This short review summarizes the recent updates on the synthesis, optical, as well as electronic properties, and the various optoelectronic applications of Ti3C2T x MXene in the materials point of view. The challenges to be overcome for their successful integration into the optoelectronics domain and opportunities for future explorations are also discussed.

We have developed a simple method to fabricate multi-walled carbon nanotube (MWNT) wiring on a plastic film at room temperature under atmosphere pressure. By irradiating a MWNT thin film coated on a polypropylene (PP) film with a laser, a conductive wiring made of a composite of MWNT and PP can be directly fabricated on the PP film. The resistance of MWNT wiring fabricated using this method were ranging from 0.789 to 114 kΩ/cm. By changing the scanning speed of laser, we could fabricate various regions with different resistances per unit length even within a single wiring. The formation mechanism of the MWNT wiring with tunable resistance was discussed from both experimental results, such as microscopic structural observation using cross-sectional scanning electron microscopy and microscopic Raman imaging, and simulation results, such as heat conduction in the film during local laser heating. The results suggest that the MWNT wiring was formed by PP diffusion in MWNT at high temperature. We also demonstrated that excess MWNTs that were not used for wiring could be recovered and used to fabricate new wirings. This method could be utilized to realize all-carbon devices such as light-weight flexible sensors, energy conversion devices, and energy storage devices.

“…The principle of photothermal means that after the material is illuminated by light, the photon energy interacts with the lattice, the vibration intensifies, and the temperature of the material increases. 33 Figure 6a shows the TPU/ANF@CNT composite fiber under the illumination of the infrared lamp. The CNT in the surface conductive layer absorbs infrared light to make the temperature rise and emits thermal photons.…”

Flexible and highly conductive fiber has attracted considerable attention with its massive potential in functional fabric, stretchable circuits, and wearable electronic devices. Herein, we prepared a novel secondary structure composite fiber based on aramid nanofibers (ANF)-reinforced thermoplastic polyurethane (TPU) fiber accompanied by carbon nanotube (CNT)-coated on its surface. The composite fibers' dispersibility, micromorphology, and application were systematically investigated. The TPU/ANF-0.5 wt% sample showed a robust reinforcing effect, as Young's modulus and tensile strength reached 17.2 and 20.2 MPa, respectively. Meanwhile, the conductive coating layer in the outer frame was formed via a TPU solution with 10 wt% CNT content, which gives the fiber excellent flexible electrical conductivity. Such a unique structural design enables the fiber to be closely attached to human skin and monitor human movement. In addition, this TPU/ANF@CNT composite fiber can also be used for light and electric heating. The photothermal equilibrium temperature can reach 120 C in 50 s, and the electrothermal equilibrium temperature increases to 62 C under 30 V. In summary, this secondary structure composite fiber with excellent electrical and mechanical properties might have great practical application potential in wearable electronic devices.
