Estimation of electrical conductivity for polymer composites with carbon black nanoparticles by interphase depth, tunneling characteristics and network percentage.
Article in Scientific reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Despite many experimented works on the conductivity of carbon black (CB)-polymer nanocomposites (PCBs), the modeling methodology in this field is imperfect requiring more development. The current article suggests a simple and accurate equation for the electrical conductivity of PCBs by CB radius, interphase depth, tunneling characteristics (λ), percolation onset, network percentage and interfacial tension. At the first step, the impact of model's parameters on the PCB conductivity is designed and justified. Then, the offered model is validated by the real data of numerous samples with dissimilar polymer media and CB nanoparticles. Bigger tunnels with the smaller widest weaken the conductivity, however the peak conductivity of 11.5 S/m is attained at tunneling distance (λ) of 2 nm and contact diameter (d) of 45 nm, while λ > 5 nm or d < 20 nm produce an insulating sample. Also, higher polymer surface energy (γ
