Competitive Adsorption in Polymer Nanocomposites: The Molecular Weight and End-Group Effect Revealed by SANS and MD Simulations.
Article in ACS applied materials & interfaces, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Understanding polymer adsorption at interfaces is essential for designing advanced polymer-based nanomaterials with tailored interfacial properties. Although adsorption significantly influences the macroscopic properties of polymer composites and thin films, a comprehensive understanding of molecular weight (MW)-dependent adsorption remains challenging and controversial, particularly in polydisperse polymer systems, due to the limitations of experimental approaches. Here, we investigate competitive adsorption in bidisperse poly(ethylene glycol) (PEG) melts and demonstrate that shorter chains preferentially adsorb onto nanoparticle surfaces. Combined experiments and molecular dynamics simulations reveal that the high density of terminal hydroxyl groups in short PEG chains strengthens hydrogen bonding at the interface, thereby inducing enthalpy-driven adsorption despite identical polymer backbones. This results in a densely packed interfacial layer that alters the conformation of longer chains. These findings highlight the critical role of end-group functionality in interfacial polymer behavior and provide new insights for tailoring nanocomposite properties.
