Multiscale interlinked structures limit fatigue crack propagation in a MXene-polyurethane composite.
Article in Nature communications, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Self-healing materials hold significant commercial potential if their mechanical properties meet industrial requirements. However, conventional viscoelastic self-healing materials face an inherent compromise between fatigue resistance and stiffness, limiting their viability as substitutes for load-bearing rubber. To overcome this challenge, we construct multiscale structures, achieved through hydrogen bonding-driven assembly of a microscale transition metal carbide/carbonitride (MXene) framework within a self-healing polyurethane matrix featuring nanoscale continuous dynamic hard phase. This synergistic design endows the resulting composite with a fatigue threshold of 8226.3 J m⁻², modulus of 51.1 MPa, self-healing with 1 min recovery activated by near-infrared irradiation, and enhanced thermomechanical stability. Mechanism analysis reveals that the nanoscale continuous hard domains, coupled with the microscale MXene framework, collectively enable multiscale stress deconcentration while suppressing thermal activation effects in the composite. This study presents promising results for designing multifunctional, high-performance polymer composites via controlled multiscale structural coupling.
