| Abstract Scope |
The structural integrity of MXene and MXene-based materials is important across many applications from sensors to energy storage. While MXene processing has received significant attention, its structural integrity for real-world applications remains challenging due to its flake-like form factor. This study investigates the mechanical response of layered MXene-polymer nanocomposites (MPC) employing a bioinspired nacre-like brick-and-mortar architecture through parameterized finite element analysis (FEA). By doing so, the research aims to uncover the factors influencing the mechanical response of these composites to offer insights into critical factors for materials processing. Specifically, an automated framework is developed to generate MPCs with a high concentration of MXene (> 70%) with nacre-like geometrical features such as aspect ratio (AR) and flake thickness and perform parameterized FEA for randomized distribution of flake geometries and varying interfacial strength. The investigation reveals that while cohesive contact strength, flake concentration, and AR significantly impact strength and toughness, local structural features like flake distribution and interphase polymer location substantially influence crack initiation, its location, and subsequent arrest or propagation. The comparison with theoretical models and existing computational and experimental work underscores the importance of interfacial strength, stress transmission, and local structural features, including the presence and location of defects in shaping the material's mechanical attributes. |
