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 Ti₃C₂T_x MXene nanosheets and prepare a novel electrically conductive adhesive based on epoxy resin filled with Ti₃C₂T_x MXene nanosheets by solution blending. The structure, morphology, and performance of Ti₃C₂Tx MXene nanosheets and epoxy/Ti₃C₂T_x MXene nanosheets composite were investigated. The results show that Ti₃C₂T_x MXene possesses nanosheet structure. Ti₃C₂T_x MXene nanosheets were homogeneously dispersed in epoxy resin. Electrical conductivity and mechanical properties measurements reveal that the epoxy/Ti₃C₂T_x MXene nanosheet composite exhibited both good electrical conductivity (4.52 × 10⁻⁴ S/m) and favorable mechanical properties (tensile strength of 66.2 MPa and impact strength of 24.2 kJ/m²) when the content of Ti₃C₂T_x MXene nanosheets is 1.2 wt %. Thus, Ti₃C₂T_x MXene is a promising filler for electrically conductive adhesive with high electric conductivity and high mechanical performance.

In this study, a novel hierarchical carbon fiber@cobalt ferrite@manganese dioxide (CF@CoFe₂O₄@MnO₂) composite was facilely prepared via a sol–gel method and hydrothermal reaction.

A novel CF@NiFe₂O₄@p-PANI hybrid was designed. Phytic acid-doped polyaniline was applied in the synthesis of an EM wave absorber. The hybrid exhibits excellent EM wave-absorbing performance.
