We demonstrate a Ti 3 C 2 T x MXene coated textile supercapacitor configured as five cells stacked in series with high operating potential range of 6 V, capable real time operation wireless sensor for over 90 minutes.
Fourier-transform infrared (FTIR) spectroscopy characterization is a powerful and easy-to-use technique frequently employed for the fingerprinting of materials. Although MXenes are large fastest growing family inorganic 2D materials, lack systematic FTIR studies hinders its application to often leads misinterpretation results. In this study, we report experimental calculated spectra 12 most typical carbide carbonitride with different compositions (5 transition metals) all four basic...
Abstract Driving the pseudocapacitive redox intercalation in 2DMXenes with neutral electrolytes is important for safer, more sustainable, and improved electrochemical charge storage. Single transition metal MXenes, such as Ti 3 C 2 , have shown great promise energy storage, owing to their high conductivity activity. Mixed metallic out‐of‐plane ordered Mo remained underexplored storage because of absence activity most electrolytes. Simultaneous structural modifications instigating...
Abstract MXenes are promising passive components that enable lithium‐sulfur batteries (LSBs) by effectively trapping lithium polysulfides (LiPSs) and facilitating surface‐mediated redox reactions. Despite numerous studies highlighting the potential of in LSBs, there no systematic MXenes’ composition influence on polysulfide adsorption, which is foundational to their applications LSB.

Abstract The origin of MXene's excellent electromagnetic shielding performance is not fully understood. MXene films, despite being inhomogeneous at the nanometer scale, are often treated as if they compared to bulk conductors. It reasonable wonder treatment a homogeneous material remains valid very small film thickness and it depends on interlayer spacing. goal present work test model applicable nanometer‐thin Ti 3 C 2 T x films and, so, investigate how parameters may depend variations in...
While transition‐metal oxides such as α‐MoO 3 provide high capacity, their use is limited by modest electronic conductivity and electrochemical instability in aqueous electrolytes. Two‐dimensional (2D) MXenes, offer metallic conductivity, but capacitance Insertion of partially solvated cations into Ti C 2 MXene from lithium‐based water‐in‐salt (WIS) electrolytes enables charge storage at positive potentials, allowing a wider potential window higher capacitance. Herein, we demonstrate that...
Abstract The rise of the Internet Things has spurred extensive research on integrating conductive materials into textiles to turn them sensors, antennas, energy storage devices, and heaters. MXenes, owing their high electrical conductivity solution processability, offer an efficient way add electronic functions through simple dip coating. However, manual development MXene‐coated restricts quality, quantity, variety. Here, a versatile automated yarn coater tailored for producing continuously...
Polyvinylidene fluoride (PVDF) is a semicrystalline polymer used in thin-film dielectric capacitors because of its inherently high constant and low loss tangent. Its can be increased by the formation alignment β-phase crystalline structure, which facilitated 2D nanofillers. carbides nitrides, MXenes, are promising candidates due to their notable permittivity ability increase interfacial polarization. Still, mixing challenging weak interactions poor dispersibility MXenes PVDF. This work...
Abstract Due to the ubiquity of textiles in lives, electronic (E‐textiles) have emerged as a future technology capable addressing myriad challenges from mixed reality interfaces, on‐garment climate control, patient diagnostics, and interactive athletic wear. However, providing sufficient electrical power textile form factor has remained elusive.
