Multifunctional self-healing supramolecular structural toughened resins, formulated to counteract the insulating properties of epoxy polymers and integrating auto-repair mechanisms, are morphologically spectroscopically characterized using Tunneling Atomic Force Microscopy (TUNA) Fourier transform infrared spectroscopy (FT-IR), respectively. Specifically, multifunctional resin comprises molecular fillers electrically conductive carbon nanotubes (CNTs) embedded in matrix. The selected molecules can form non-covalent bonds with hydroxyl (OH) carbonyl (C=O) groups matrix through their H-bonding donor acceptor sites. An FT-IR analysis has been conducted evaluate interactions that barbiturate acid derivatives, serving as fillers, constituent parts blend. highlights morphological characteristics CNTs, dispersion within polymeric matrix, affinity for globular rubber domains. TUNA technique maps samples’ electrical conductivity at micro- nanoscale spatial Detecting currents reveals networks, determined by hydrogen bonds, samples, showcasing features sample containing an nanofiller hosting
