520	3		_aThe rapid growth of the electronic industry has led to increased electromagnetic (EM) wave production, posing health risks and causing electromagnetic interference (EMI). This highlights the need for effective EM shielding materials. This thesis develops carbon-doped titanium carbonitride (TiCN)/epoxy nanocomposites as efficient EM shielding materials. The carbon-doped TiCN, known for its excellent conductivity, enables absorption and reflection of EM waves, while the epoxy matrix enhances chemical and thermal stability, as well as dielectric properties. Carbon-doped TiCN was synthesized via hydrothermal methods and characterized using X-ray Diffraction (XRD), Fourier Transform Infrared Spectroscopy (FTIR), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDX), and BrunauerEmmett-Teller (BET) analysis. Key findings include dominant XRD peaks corresponding to TiCN crystallinity, uniform carbon dispersion on TiCN particles as revealed by FESEM, and FTIR identification of functional groups such as C-N, C-O, TiN, Ti-O, and Ti-C. BET analysis showed the highest surface area of 9.59 m²/g for the 2:1 sample. The nanocomposites were fabricated by mixing carbon-doped TiCN with epoxy resin and evaluated using a Vector Network Analyzer (VNA) in the X-band frequency range (8.2–12.4 GHz). The 5:1 sample achieved the highest shielding effectiveness (SE) of 9.1 dB at 10.5 GHz with a 2 mm thickness. Additionally, 20% filler demonstrated maximum SE of 8.9 dB at 10.6 GHz. These results suggest that carbon-doped TiCN/epoxy nanocomposites are promising materials for mitigating EM wave pollution, particularly with optimized doping and filler compositions
