Investigation of the Effect of Dispersion Route Using Solvent and Melt Mixing in Linear Low‐Density Polyethylene ( LLDPE ) and Carbon Nanofibers Nano‐Composite

Year: 2025

Type: article

Abstract: ABSTRACT Processing route plays a decisive role in tailoring the multifunctional performance of carbon nanofiber (CNF)‐reinforced polymer nanocomposites. Here, melt mixing and solution processing were compared to evaluate their influence on volume resistivity, thermal conductivity, and electromagnetic interference (EMI) shielding. Solution‐processed composites achieved superior conductivity at lower CNF loading (1.0 wt%) due to improved dispersion and network formation, while melt‐mixed composites required higher loading (3.0 wt%) for comparable performance. Thermal conductivity and EMI shielding effectiveness also improved with increasing CNF content, with absorption dominating the shielding mechanism. These findings highlight the potential of CNF‐reinforced polymer composites for advanced electrical and EMI shielding applications, with processing route playing a key role in tailoring multifunctional properties.
