Multi-walled carbon nanotube/polyethersulfone nanocomposites for enhanced electrical conductivity, dielectric properties and efficient electromagnetic interference shielding at low thickness

Herein, we report the synthesis of a high performance electromagnetic interference shielding (EMI) composite by utilizing polyethersulfone (PES) as a model matrix. Thin films of PES filled with conductive multi-walled carbon nanotubes (MWCNTs) were fabricated by a simple solution casting technique. The effect of filler concentration on EMI shielding efficiency, dielectric constant, electrical conductivity, hardness and thermal stability were...
