Abstract As a novel type of transition metal-based 2D materials, the most popular MXene (Ti₃C₂T_x，where T is a surface termination, typically O, OH, and/or F) has been endowed amazing prospects in versatile fields, including energy storage, electromagnetic interference shielding, electronics and photon-detectors. At the same time, the inevitable oxidation structure observed in experiment also affect the property of MXene. With the help of the surface termination and surface oxidation, MXene showed diversity magnetic, electronic and optical behavior. However, our knowledge about the fundamental thermal and mechanical properties of MXene is limited, especially regarding the effect of surface structure on the mechanical… More >

Abstract With the advancement of technology, shielding for terahertz (THz) electronic and communication equipment is increasingly important. The metamaterial absorption technique is mostly used to shield electromagnetic interference (EMI) in THz sensing technologies. The most widely used THz metamaterial absorbers suffer from their narrowband properties and the involvement of complex fabrication techniques. Materials with multifunctional properties, such as adjustable conductivity, broad bandwidth, high flexibility, and robustness, are driving future development to meet THz shielding applications. In this article, a theoretical simulation approach based on finite difference time domain (FDTD) is utilized to study the absorption and shielding characteristics of a two-dimensional… More >

Abstract Waterborne polymers are vital for coating industry to reduce carbon emissions. However, formation of robust and self-healable films at ambient temperature remains a challenge owing to high energy cost of film formation process. This work reports a solar-driven film formation of waterborne polyurethanes (WPUs) containing disulfide bonds via in-situ incorporation of 2D titanium carbide (MXene) with ability to convert light to heat. Instead of directly mixed with WPUs, MXene is added to join the reaction with isocyanate-terminated pre-polymer before emulsification process. This approach not only prevents aggregation of MXene in water but stabilizes MXene against thermal degradation which is the… More > Graphic Abstract

Abstract In this study, nanocomposite of ternary nitrate molten salt induced with MXene is developed. LiNO₃-NaNO₃-KNO₃ with wt% of 35:12:53 and 35:10:55 are produced and doped with MXene in the wt% of 0.2, 0.5, 1.0, and 1.5. FTIR result indicates the composites had no chemical reaction occurred during the preparation. UV-VIS analysis shows the absorption enhancement with respect to the concentration of MXene. Thermogravimetric analysis (TGA) was used to measure the thermal stability of the LiNO₃-NaNO₃-KNO₃ induced with MXene. The ternary molten salts were stable at temperature range of 600–700°C. Thermal stability increases with the addition of MXene. 1.5 wt% of… More >
