Abstract

fetched live from OpenAlex

Abstract Lightweight and flexible materials with high conductivity and low thickness are highly desirable for electromagnetic interference (EMI) shielding applications. Developing hybrid nanostructured materials, which combine the properties of their constituents, is an excellent strategy to create highly effective EMI shields. In this study, we report a hybrid polymer nanocomposite composed of carbon nanotube (CNT) and ZnO nanowire (ZnONW) for EMI shielding applications. We found that the combination of a conductive filler (CNT) and a dielectric filler (ZnONW) with a similar geometry is an effective method to fabricate nanocomposites with enhanced EMI shielding. We achieved high average shielding effectiveness of 27.3 dB (with a maximum of 41 dB at 10.2 GHz) for a sample of CNT:ZnONW (5.0:2.5 wt%) with only 1.1 mm thickness, which is among the best‐reported values in the literature for polymer nanocomposites with similar filler loading and thickness. This performance originates from the excellent electrical conductivity and dielectric properties of hybrid nanocomposites, combined with the geometry of ZnO nanowire. A comparison of the shielding properties of the developed hybrid nanocomposites with the literature implies that they are promising functional materials in the world of EMI shielding applications.

Teacher imitation

Not 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.
