| contents | This thesis thoroughly investigates the production, characterization, and applications of graphene-based materials (GBMs) and amorphous magnetic materials, particularly in electromagnetic shielding and gas sensing. Four main research lines are pursued: GBM production, GBMs and amorphous magnetic materials in shielding applications, GBMs in gas sensors, and amorphous magnetic materials in magnetoelastic resonance-based sensors. Scalable methods for GBM production are explored, including ball milling, yielding few-layered mesoporous graphene (FLMG). FLMG enhances electromagnetic shielding when combined with amorphous magnetic microwires (MW), showing synergistic effects. FLMG also demonstrates effective NO2 detection in gas sensors, with UV irradiation improving sensor performance. Amorphous magnetic materials show promise in magnetoelastic resonance-based sensors for biomedical applications. Overall, this thesis addresses current limitations in electromagnetic shielding and gas detection, supported by patents and scientific publications. |
