| Abstract Scope |
MXenes are a class of 2D transition metal carbides, nitrides, or carbonitrides. They hold promise for applications in energy storage, catalysis, and electronics due to their exceptional properties. MXenes have garnered significant attention for their potential to reinforce polymer matrices by enhancing electrical conductivity and mechanical properties. This study explores the mechanical behavior of MXene/PVDF composites under various loading conditions using in situ mechanical testing in a scanning electron microscope. The research quantitatively assesses how different concentrations of MXene influence the composite’s mechanical strength, deformation, fracture, and electrical conductivity. Additionally, NanoCT is used to investigate these materials for defects and morphological changes in three dimensions. Using these advanced techniques, we observed structural changes, capturing critical phenomena such as crack development and interactions at the interface between MXene flakes and the PVDF matrix during loading. Our findings indicate a significant enhancement in both mechanical strength and conductivity with increased MXene content. |
