Predicting of tunneling conductivity for polymer-carbon black nanocomposites by interphase percolation.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Earlier studies primarily focused on the experimental aspects of percolation onset and conductivity in polymer/carbon black (CB) nanocomposites, but the modeling approach was largely underexplored. In this study, a new equation is developed to determine the CB percolation threshold, taking into account the superficial properties of CB and polymer, as well as crucial terms such as CB radius (R) and interphase thickness (t). Also, a model is advised to simulate the conductivity of CB-filled examples by accounting for R, contact circle diameter, the number of contacts, and "t". Validation by laboratory data confirms the reliability of the proposed model. The results indicate that a smaller "R" and a higher volume portion of CB significantly enhance the conductivity, achieving 7.7 S/m at minimum R = 5 nm and the highest CB volume fraction of 0.036. A direct correlation is also found between the number of CB contacts (m) and composite conductivity, where the highest network volume portion of 0.88 and supreme m = 37 produce the supreme conductivity of 2.45 S/m.
