Viscoelastic Response of Poly(dimethylsiloxane) in the Adhesive Interaction with AFM Tips
Bibliographic record
Abstract
As follow-up to a previous study,(1) the viscoelastic response of cross-linked poly(dimethylsiloxane) (PDMS) in the adhesive interaction with AFM tips is reported. The indentation of the AFM tip into the polymer caused by adhesion is monotonically dependent on the loading speed. During the unloading process, the adherence force between the AFM tip and the polymer has a turning point at a specific unloading speed. It is found that the viscoelastic relaxation processes in the bulk polymer, which may have more than one component, cause the monotonic rate dependence of the adhesion-induced indentation; the competition between the bulk relaxation and the interfacial relaxation results in the turning point of the adherence force at a specific ramp speed. Experiments at different dwell times provide additional evidence for the existence of material relaxation. Methyl- and hydroxyl-functionalized AFM tips were used to study PDMS samples and indicated strong dipolar attractions formed at the tip-sample interface.

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.
