This work investigates the design and electrothermal behavior of epoxy-based vitrimers (epoximers) with tunable dynamic properties and embedded carbon nanomaterials. By integrating transesterification-based exchangeable networks with conductive fillers, these materials exhibit controlled mechanical properties, electrical conductivity, and processability. These transesterification-based vitrimer/epoxy hybrid systems are catalyzed by 1,5,7-triazabicyclo [4.4.0] dec-5-ene (TBD). The resulting composites can be selectively heated using electromagnetic fields, including radiofrequency and plasma sources, enabling rapid reshaping, reversible adhesion, and localized repair without the need for bulk thermal curing. These epoximer networks combine the high mechanical strength of traditional epoxies with the dynamic bond exchange behavior of vitrimers, enabling reprocessability and reshaping without compromising stiffness. Increasing vitrimer content enhances dynamic exchange and reconfigurability, while higher epoxy content raises the glass transition temperature. Incorporation of carbon nanotubes (CNTs) imparts electrical conductivity and enables selective, non-contact heating using RF fields. The study establishes clear relationships between network chemistry, filler loading, and field-induced heating efficiency, revealing design rules for programmable vitrimer behavior. Beyond reprocessability, the enhanced electrical and dielectric response of CNT-loaded epoximers makes them promising candidates for electromagnetic interference (EMI) shielding and other multifunctional applications where structural adaptability is critical.
