Decoupling Rheological and Electrical Percolation Thresholds in CNT-Reinforced Polypropylene Nanocomposites: A Framework for Tunable Multifunctionality Maziyar Sabet Polymer Composites, 2026 This study quantifies the dual percolation behavior of carbon‐nanotube (CNT)–reinforced polypropylene (PP) by pairing dynamic oscillatory rheometry, impedance spectroscopy, and scanning electron microscopy (SEM) across matched loadings. A rheological (stress‐bearing) network emerges at ~0.30 wt% CNT, evidenced by a low‐frequency G′ plateau, while electrical percolation occurs at ~0.40 wt%, producing a rise of ≈6 orders of magnitude in DC conductivity. All datasets are reported as discrete points with mean ± SD ( n ≥ 3). Fitting σ ( ϕ ) to a percolation law, σ = σ 0 ( ϕ − ϕ c ) t for ϕ ≥ ϕ c , yields the critical loading ( ϕ c ) and exponent ( t ), thereby decoupling stress‐bearing connectivity from charge transport. SEM corroborates network densification across the percolation window. The resulting design map—insulating → rheologically percolated (dielectric) → electrically percolated (conductive)—enables independent tuning of mechanical reinforcement and electrical functionality for applications ranging from structural dielectrics to sensing and EMI shielding. The framework provides a practical route to structure–property control in CNT‐based macromolecular systems under scalable processing.
AI-Assisted Design of Halogen-Free EVA/Mg(OH)2–CNT/GNP Nanocomposites for Enhanced Electrical, Thermal, and Flame-Retardant Performance Maziyar Sabet, Amalia Batrisyia Binti Ans Nawi, D. M. Reddy Prasad Polymer Engineering and Science, 2026 Flexible and wearable electronics require polymer composites that unite electrical conductivity, thermal management, mechanical compliance, and inherent flame retardancy. Conventional halogen‐free EVA systems often optimize a single property and rely on qualitative dispersion assessment, limiting reproducibility and low‐loading multifunctionality. Here, EVA/Mg(OH) 2 nanocomposites reinforced with hybrid multi‐walled carbon nanotubes (MWCNTs) and graphene nanoplatelets (GNPs) were evaluated using an AI‐assisted FESEM image‐segmentation framework. Dispersion was quantified via network connectivity, inter‐particle distance, and agglomeration index, and these metrics correlated strongly with electrical and thermal transport. The optimized 5 wt% hybrid formulation achieved σ = 1.4 × 10 −2 S m −1 , k = 0.62 W m −1 K −1 , EMI shielding effectiveness > 20 dB in the X‐band (8–12 GHz), and UL 94 V‐0 classification, while retaining flexibility. The electrical percolation threshold (~4 wt%) was markedly lower than many EVA benchmarks, confirming the efficiency of the 1D–2D hybrid network. By advancing dispersion analysis from qualitative observation to a quantifiable design variable, this work establishes a data‐driven pathway for scalable, halogen‐free nanocomposites. The results highlight routes to lightweight, multifunctional materials for flexible electronics, automotive electronics, and aerospace thermal management, underscoring the role of AI‐enabled analysis in polymer‐engineering design.
Processing-driven alignment of carbon nanotubes and crystallization control in thermoplastic nanocomposites: In-situ structural and rheological analysis Maziyar Sabet Journal of Thermoplastic Composite Materials, 2026 This study investigates the coupled influence of shear-induced carbon nanotube (CNT) alignment and crystallization control in thermoplastic nanocomposites, providing real-time insight into processing–structure–property relationships. Using in-situ wide-angle X-ray diffraction (WAXD), differential scanning calorimetry (DSC), and rotational rheology, we track the evolution of CNT orientation and crystallization kinetics in a high-density polyethylene (HDPE) matrix under controlled shear. A critical shear threshold of ∼100 s −1 is identified, above which CNTs transition from a random to a highly aligned state, with the orientation factor increasing from 0.12 to 0.87. This alignment markedly accelerates crystallization, elevating the onset temperature by up to 8°C and reducing induction time by more than 50%. Aligned CNTs act as efficient nucleating agents and thermal pathways, generating anisotropic lamellar morphologies and enhanced thermal stability. The synergistic effects of CNT concentration and shear intensity yield a quantitative framework linking processing parameters, structural descriptors, and crystallization response. The methodology and correlations established here provide processing-embedded strategies to engineer thermoplastic nanocomposites with tunable thermal, mechanical, and structural performance, directly relevant to extrusion, fiber spinning, and additive manufacturing.
