Cooperative principle in multiple glass transitions and strain relaxations of thermochemically responsive shape memory polymer
Bibliographic record
Abstract
Abstract Cooperative principle in shape memory polymers (SMPs) result in their effective communication with the external thermochemical stimuli and then the SMPs act cooperatively to generate stimulus-responsive shape memory effect (SME). Their SME can be triggered by chemical stimuli and the corresponding thermochemically responsive behaviors are often explained by the reversible rearrangement of macromolecule segments due to changes of their configurational entropy. In this paper, we propose a new cooperative model to describe the multiple glass transitions and strain relaxations of an SMP in response to the water by means of selective and chemical plasticization effect on the partial segments in a macromolecule. Based on this model, the plasticization effect on the glass transition temperature, relaxation time and recovery strain of the SMP have been systematically investigated. Finally, the constitutive model for thermochemically responsive SMPs with two viscoelastic transitions and multiple SMEs was established to describe their overall mechanical responses, and a good agreement between the numerical and experimental results has been achieved.

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.
