Abstract: Novel tertiary nanocomposite films comprising of poly (vinyl alcohol) (PVA), poly (4-styrenesulfonic acid) (PSSA) and titanium dioxide (TiO<subscript>2</subscript>) nanoparticles (NP<subscript>S</subscript>) were prepared using simple solvent casting method. The structural, thermal, morphological, thermo-mechanical and electromagnetic interference (EMI) shielding properties of PVA/PSSA/TiO<subscript>2</subscript> nanocomposite films were investigated. The EMI shielding effectiveness (SE) of PVA/PSSA/TiO<subscript>2</subscript> nanocomposite films in the X and Ku band was found to be 12 dB and 13 dB respectively at 25 wt% TiO<subscript>2</subscript> NPs loading. These results demonstrate the possible applications of PVA/PSSA/TiO<subscript>2</subscript> nanocomposite films as low cost, lightweight and flexible material for EMI shielding.
