| Abstract Scope |
Epoxy resins are widely used in electronic packaging and microelectronic applications because of their mechanical strength, thermal stability, chemical resistance, processability, and insulating properties. However, advanced electronic systems require epoxy-based materials with controlled electrical conductivity for electrostatic dissipation, antistatic protection, sensing, and reliable device performance. In this work, MWCNT/ Cd3As2/ epoxy hybrid nanocomposites were prepared to improve the electrical response of the epoxy matrix. Multi-walled carbon nanotubes were introduced as conductive fillers to form interconnected charge-transport pathways, while Cd₃As₂, a stable three-dimensional Dirac semimetal with high carrier mobility and giant magnetoresistance, was used as a functional semimetallic additive. The composites were characterized by electrical conductivity and impedance measurements, supported by X-ray diffraction, Raman spectroscopy, and scanning electron microscopy. The MWCNT/ Cd3As2 hybrid filler system is proposed as a promising approach for conductive epoxy nanocomposites for antistatic electronic packaging, flexible sensors, and magnetic-field-sensitive electronic devices. |
