20.500.12556/RUL-182613 Mechanistic structure–property relationships in carbon/polymer composites: connectivity, junction resistance, and durability Carbon/polymer composites are increasingly designed as microstructure-engineered multifunctional materials that combine mechanical reinforcement with electrical/thermal transport, electromagnetic interference (EMI) shielding, and sensing. Performance is governed less by filler fraction than by the coupled control of network topology, junction resistance, and interfacial thermal boundary resistance under processing-induced shear and thermal histories. Electrical response follows percolation combined with tunneling/contact-controlled junctions, producing nonlinear σ(φ) behavior and high piezoresistive sensitivity near the percolation threshold. In contrast, thermal transport is commonly limited by Kapitza resistance and filler–filler junction resistance, restricting exploitation of the intrinsic conductivity of CNTs and graphene. Recent advances emphasize hybrid and 3D carbon architectures that densify connectivity, reduce junction losses, and enable programmable anisotropy via scalable routes such as masterbatch extrusion and additive manufacturing. However, translation remains constrained by dispersion-driven variability, transport–toughness trade-offs, and incomplete durability assessment under cycling, humidity, and reprocessing. This review consolidates mechanistic structure–processing–property relationships and provides application-driven design rules for sensors, EMI shielding, and thermal management. carbon-polymer composites percolation and tunneling interfacial thermal resistance hybrid architecture 3D architecture durability recyclability kompoziti iz ogljika in polimerov kontaktne povezave medfazni toplotni upor hibridna arhitektura tridimenzionalna arhitektura trajnost možnosti recikliranja true false true Angleški jezik Slovenski jezik Članek v reviji 2026-05-19 10:15:01 2026-05-19 10:15:14 2026-05-20 04:45:55 0000-00-00 00:00:00 2026 0 0 46 str. issue 10, art. 1220 Vol. 18 2026 0000-00-00 Zaloznikova Objavljeno apc 0000-00-00 0000-00-00 0000-00-00 620.1:678.7 2073-4360 10.3390/polym18101220 278600963 Sharma,_Klobcar_..._Mechanistic_structure...pdf Sharma,_Klobcar_..._Mechanistic_structure...pdf 1 1E08714555CA530918BB06D20325AB97 d1980da06b933212bff8d2b0fc944d2a5dfcd7881a5779747f7b065b1fe271b3 f6ea49d5-535a-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234026 https://www.mdpi.com/2073-4360/18/10/1220 1 8fd487ff-535a-11f1-b0ab-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=234025 Fakulteta za strojništvo 0 0 0
