Hierarchical Interfacial Assembly of ABC Triblock Copolymer
Bibliographic record
Abstract
Hierarchical assembly, allowing molecular order and structural control at multilength scales, is the basis of life itself and may be used in the fabrication of future electronic, optical, and other devices. Despite its importance, hierarchical assembly has been seldom practiced for block copolymers in solvents. This paper reports a method for the two-tier assembly of block copolymers. At tier 1, an ABC triblock copolymer is self-assembled into spherical or cylindrical micelle-like aggregates in decahydronaphthalene (DN) with the B block making up the insoluble core and the A and C blocks making up the soluble corona. At tier 2, the aggregates are further assembled by adsorption via the Pickering effect on surfaces of droplets of methanol that is immiscible with DN, has been added into the DN aggregate solution, and solubilizes the C block but not the A and B blocks. While the final 3-D shape of the hierarchically assembled block copolymer is invariably spherical, the 2-D morphologies are different being ordered ribbons at 52 ± 2 °C and balls in sockets at 22 ± 2 °C.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
