MXene represents new kinds of two-dimensional material transition metal carbides and/or carbonitrides, which have attracted much attention in various applications including electrochemical storage devices, catalysts, and polymer composite. Here, we report a facile method to synthesize TiCT MXene nanosheets and prepare a novel electrically conductive adhesive based on epoxy resin filled with TiCT MXene nanosheets by solution blending. The structure, morphology, and performance of TiCTx MXene nanosheets and epoxy/TiCT MXene nanosheets composite were investigated. The results show that TiCT MXene possesses nanosheet structure. TiCT MXene nanosheets were homogeneously dispersed in epoxy resin. Electrical conductivity and mechanical properties measurements reveal that the epoxy/TiCT MXene nanosheet composite exhibited both good electrical conductivity (4.52 × 10 S/m) and favorable mechanical properties (tensile strength of 66.2 MPa and impact strength of 24.2 kJ/m) when the content of TiCT MXene nanosheets is 1.2 wt %. Thus, TiCT MXene is a promising filler for electrically conductive adhesive with high electric conductivity and high mechanical performance.
MXene是一类新型的二维材料，即过渡金属碳化物和/或碳氮化物，在包括电化学存储设备、催化剂和聚合物复合材料在内的各种应用中备受关注。在此，我们报道了一种简便的方法来合成TiCT MXene纳米片，并通过溶液共混制备一种基于填充有TiCT MXene纳米片的环氧树脂的新型导电胶粘剂。研究了TiCTx MXene纳米片以及环氧/TiCT MXene纳米片复合材料的结构、形态和性能。结果表明，TiCT MXene具有纳米片结构。TiCT MXene纳米片均匀分散在环氧树脂中。电导率和力学性能测试表明，当TiCT MXene纳米片的含量为1.2 wt%时，环氧/TiCT MXene纳米片复合材料同时具有良好的电导率（4.52×10 S/m）和优异的力学性能（拉伸强度为66.2 MPa，冲击强度为24.2 kJ/m）。因此，TiCT MXene是一种用于具有高电导率和高力学性能的导电胶粘剂的有前景的填料。
