The demand for effective electromagnetic interference (EMI) shielding has driven the development of advanced materials combining magnetic and dielectric properties. This study presents a composite paint with cobalt ferrite (CoFe₂O₄) nanoparticles (5 wt%) and wood shavings (10 wt%) for enhanced EMI shielding in the 3.2–5.0 GHz range. Wood shavings improved electromagnetic wave absorption through their porous structure and dielectric properties, complementing CoFe₂O₄’s magnetic loss characteristics. The paint achieved a peak absorption shielding effectiveness (SE) of 12 dB, surpassing the 10 dB of the CoFe₂O₄-only system. Reflection SE values were reduced to -1 to +1 dB. This eco-friendly and cost-effective material offers significant potential for industrial and defense applications.
