Mechanical Behavior and Fracture Mechanisms of MXene/PVDF Nanocomponsites: In Situ Characterization and Multiscale Analysis

ABSTRACT The integration of two‐dimensional (2D) MXene nanosheets into polyvinylidene fluoride (PVDF) matrices enables the design of multifunctional nanocomposites with enhanced properties. However, most attention has been dedicated to their electrical and dielectric characteristics, with information about the effect of MXene on mechanical properties being limited. This study systematically investigates the mechanical performance, fracture behavior, and interfacial mechanics of PVDF‐based compos
