Abstract

Surface modification of MXenes significantly expands their potential for a wide range of applications. Here, we demonstrate a one-pot spontaneous polymerization of acrylic acid onto MXene sheet surfaces using an aryl diazonium coupling agent (nitrobenzene diazonium salt) as an approach to tune MXene interfacial properties. We use this formation of polymer coatings as a coagulation strategy for spinning fibers from liquid crystal MXene dispersions, obtaining densified free-standing fibers with tensile strength and breaking energy of ∼155 MPa and ∼4.5 MJ m⁻³. This simple method potentially offers a scalable approach for fabricating functional MXene macroarchitectures.

改性 Ti3C2Tx MXene 表面的一锅法策略

MXenes 的表面改性大大拓展了其广泛应用的潜力。在这里，我们展示了一种使用芳基重氮偶联剂（硝基苯重氮盐）在 MXene 片材表面进行丙烯酸单锅自发聚合的方法，以此来调整 MXene 的界面特性。我们利用这种聚合物涂层的形成作为一种凝结策略，从液晶 MXene 分散体中纺制纤维，从而获得致密的独立纤维，其拉伸强度和断裂能分别为 ∼155 MPa 和 ∼4.5 MJ m-3。这种简单的方法有可能为制造功能性 MXene 宏架构提供一种可扩展的方法。

期刊介绍： Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance: A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting. B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
