Abstract
Herein, we report the first oxygen (O 2 ) and carbon dioxide (CO 2 ) dual gas-switchable thermoresponsive polymers based on a newly synthesized monomer N -(2-fluoroethyl amide)- N -(2-(diethylamino)ethyl) acrylamide, that is, AM(F1EA-DEAE), which bears both O 2 -switchable fluorinated ethyl amide (F1EA) and CO 2 -switchable N, N -diethylamino ethyl (DEAE) moieties on its side chain. PolyAM(F1EA-DEAE) samples prepared from reversible addition–fragmentation chain transfer (RAFT) polymerization exhibited good temperature-responsive properties. Their inherent low critical solution temperature (LCST) could be reversibly tuned to different levels by respectively purging O 2 or CO 2 into its aqueous solution. The O 2 -treatment shifted LCST to a higher temperature, while the CO 2 -treatment made the polymer fully water-soluble. The polymer could be readily recovered to its initial state by washing off the trigger gas with an inert gas such as nitrogen. This work provides an effective monomer design approach for the preparation of O 2 and CO 2 dual gas-responsive polymers.

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
