Unveiling the Critical Role of Surface Oxidation of Electroresponsive Behaviors in Two-Dimensional Ti<sub>3</sub>C<sub>2</sub>T<sub><i>x</i></sub> MXenes
Bibliographic record
Abstract
Here, two-dimensional (2D) C/TiO2 hybrids synthesized via oxidation of Ti3C2Tx MXenes are reported as an ideal electrorheological (ER) candidate in pursuit of high ER efficiency. The lamellar structure of conductive carbon layers provides abundant electron transport channels, aiming to shorten the response time to an electric field, while the TiO2 nanoparticles deliver high surface polarization leading to high ER effects. The oxidation degrees of Ti3C2Tx MXenes are systematically controlled through the hydrothermal method (h-C/TiO2) or CO2 calcination (c-C/TiO2). We comprehensively studied the relationship between the surface oxidation and ER behaviors of these C/TiO2 hybrids. It was found that the h-C/TiO2 hybrid exhibited superior ER behaviors compared with the c-C/TiO2 hybrid. The holey h-C/TiO2 architecture creates large electron and oil transport pathways, which is responsible for the superior ER performances. Overall, this research provides original insights into the exciting electroresponsive materials of this quickly growing 2D MXene family as well as provides a guideline for processing oxidation of MXenes for diverse applications.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
