| 10 | Tailoring MXene Thickness and Functionalization for Enhanced Room‑Temperature Trace NO_(2) Sensing显示文摘In this study,precise control over the thickness and termination of Ti3C2TX MXene flakes is achieved to enhance their electrical properties,environmental stability,and gas-sensing performance.Utilizing a hybrid method involving high-pressure processing,stirring,and immiscible solutions,sub-100 nm MXene flake thickness is achieved within the MXene film on the Si-wafer.Functionalization control is achieved by defunctionalizing MXene at 650℃ under vacuum and H2 gas in a CVD furnace,followed by refunctionalization with iodine and bromine vaporization from a bubbler attached to the CVD.Notably,the introduction of iodine,which has a larger atomic size,lower electronegativity,reduce shielding effect,and lower hydrophilicity(contact angle:99°),profoundly affecting MXene.It improves the surface area(36.2 cm^(2) g^(-1)),oxidation stability in aqueous/ambient environments(21 days/80 days),and film conductivity(749 S m^(-1)).Additionally,it significantly enhances the gas-sensing performance,including the sensitivity(0.1119Ωppm^(-1)),response(0.2% and 23%to 50 ppb and 200 ppm NO_(2)),and response/recovery times(90/100 s).The reduced shielding effect of the–I-terminals and the metallic characteristics of MXene enhance the selectivity of I-MXene toward NO2.This approach paves the way for the development of stable and high-performance gas-sensing two-dimensional materials with promising prospects for future studies. | Muhammad Hilal Woochul Yang Yongha Hwang Wanfeng Xie | 2024 | Nano-Micro Letters2024，16，5： | 0 |
| 11 | 3D Monte Carlo simulation modeling for the electrical conductivity of carbon nanotube-incorporated polymer nanocomposite using resistance network formation显示文摘High electrical and thermal conductivity associated with high stiffness and strength offer tremendous opportunities to the development of a series of carbon nanotube incorporated composite materials for a variety of applications.In particular,a small amount of carbon fibers or carbon nanotubes in a non-conductive polymer will transform a composite into a conductive material,which reveals superb potential of their future application in electronic devices.The relation between the amount of carbon nanotubes in a polymer and the electrical conductivity of it can be studied experimentally as well as theoretically with various simulation models.A three-dimensional (3D) Monte Carlo simulation model using resistance network formation was developed to study the relation between the electrical conductivity of the polymer nanocomposite and the amount of carbon nanotubes dispersed in it.In this model,carbon nanotubes were modeled as curvy cylindrical nanotubes with various lengths and fixed tube diameter,all of which were randomly distributed in a non-conductive constrained volume,which represents polymer.The model can be used to find the volumetric electrical resistance of a constrained cubic structure by forming a comprehensive resistance network among all of the nanotubes in contact.As more and more nanotubes were added into the volume,the electrical conductivity of the volume increases exponentially.However,once the amount of carbon nanotubes reached about 0.1 % vt (volume percentage),electrical percolation was detected,which was consistent with the experimental results.This model can be used to estimate the electrical conductivity of the composite matrix as well as to acquire the electrical percolation threshold. | Nanzhu Zhao Yongha Kim Joseph H.
