Self-assembly of inverted phases in AB/CD diblock copolymer blends
Bibliographic record
Abstract
Conventional ordered phases of block copolymers are nanoscopic structures with discrete domains (spheres or cylinders) composed of the minority blocks embedded in a continuous matrix composed of the majority blocks. Inverted phases of block copolymers refer to the novel ordered structures with discrete domains composed of the majority blocks. In this work, the formation and relative stability of various inverted phases in AB/CD diblock copolymer blends are studied using self-consistent field theory. The results reveal that the ratio of the block copolymer lengths and the copolymer concentration play a crucial role in stabilizing the inverted structures, and the relative stability of various inverted phases depends sensitively on the interaction strengths. The spatial distribution of the different blocks is used to elucidate mechanisms for the formation of inverted phases. The findings provide insights into the formation of inverted phases and suggest design strategies for functional nanostructures with potential applications in nanolithography and photonic crystals.

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.
