Abstract
Understanding the interfacial shear strength (ISS) of MXenes is essential for improving their mechanical reliability in applications where layered MXene structures experience repeated mechanical loads. The ISS governs the ability of adjacent layers to resist sliding or delamination. This study investigates the ISS and associated interfacial properties of Ti 3 C 2 T x -Ti 3 C 2 T x , Ti 3 C 2 T x -graphene, and Ti 3 C 2 T x -MoS 2 interfaces through a combination of friction force microscopy and density functional theory (DFT) calculations. Experimental results show that the Ti 3 C 2 T x -Ti 3 C 2 T x homo-interface demonstrates the strongest interactions, with the highest ISS, coefficient of friction, and adhesion energy, compared to the Ti 3 C 2 T x -graphene and Ti 3 C 2 T x -MoS 2 hetero-interfaces. Furthermore, DFT simulations based on experimentally relevant compositions and configurations highlighted the critical influence of surface terminations (including −H, −F, −OH, −O, and −Cl groups) on the interfacial behavior of heterostructures. These findings offer mechanistic insights into the role of surface chemistry in tuning friction and adhesion, providing a foundation for the design of robust MXene-based interfaces.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
