Large Area, Highly Transparent, and Mechanically Stable Adhesive Films with Tunable Refractive Indices
Bibliographic record
Abstract
Abstract Optical bonding with both excellent mechanical and optical properties is highly desirable for many advanced optical device applications. This paper presents a facile method for fabricating large‐area, highly transparent, and mechanically stable adhesive films with a tunable refractive index (RI) by the layer‐by‐layer (LbL) assembly of cationic branched poly(ethylenimine) (PEI) and an anionic blend of poly(acrylic acid) (PAA) and poly(4‐styrenesulfonic acid) (PSS). Scanning electron microscopy and atomic force microscopy studies indicate that the resulting (PEI/PAA–PSS)* n adhesive films with n PEI/PAA–PSS deposition layers are smooth and homogeneous. A satisfactory bonding strength is demonstrated for both two‐sided and one‐sided bonding methods, which provide a bonding strength greater than 5.71 ± 0.71 MPa. A linearly tunable RI from 1.5410 to 1.5792 is achieved with a transparency greater than 94% in the visible region. Moreover, the preparation and debonding of adhesive films can be conducted in water, which is convenient and environmentally friendly.

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.
