Plasmon assisted Ti₃C₂T_x grafting and surface termination tuning for enhancement of flake stability and humidity sensing performance

Abstract

Humidity sensors play a critical role in monitoring human activities, environmental health, food processing and storage, and many other fields. Recently, some 2D materials, particularly MXenes, have been considered as...

Wholly degradable quasi-solid-state thermocells for low-grade heat harvesting and precise thermal sensing

“…1k, all XRD spectra of the PEDOT:PSS/Ti 3 C 2 T x composite films exhibited characteristic peaks corresponding to the (002), (004), and (008) planes of Ti 3 C 2 T x . 48 The (002) peaks were zoomed in (inset of Fig. 1k) and the corresponding interlayer spacing of the (002) planes was determined using the Bragg equation, which was found to be 13.347, 13.900, 14.167, and 14.781 Å for the pure Ti 3 C 2 T x film, PT 1-5, PT 1-2, and PT 1-1, respectively.…”

Printed High-Adhesion Flexible Electrodes Based on an Interlocking Structure for Self-Powered Intelligent Movement Monitoring

“…Transition metal carbides, carbonitrides, and nitrides, called MXenes, are a new and popular family of two-dimensional materials. − MXene-based materials and devices have been extensively used in the fields of energy harvesting and storage , and flexible electronics , as a result of their high conductivity, controllable surface terminal, and adjustable morphologies. − The generic chemical formula of MXenes is M n +1 X n T x , where M is a transition metal, X is C or N, and T is a surface terminator. , MXenes are typically obtained by selectively removing the “A-element” layer (Al or Ga) from the MAX phase by chemical etching methods. , Therefore, solution-processed MXene enables the use of printing and coating technologies for device fabrication, , such as transistors, radio-frequency antennas, supercapacitors, flexible sensors, , and patterned conductive electrodes . Printing technologies present critical advantages over traditional vacuum filtration and self-assembly methods, including a simple fabrication process, compatibility with the target substrate, cost performance, and large-volume manufacturing. , …”
