Abstract
This present article deals with the development and characterization of nanocomposite for Electromagnetic interference (EMI) shielding application of medical instruments used in medical facility environment. Polymer conducting nanocomposite (PCNC) to provide EMI shielding effect has been developed using the carbon based conducting filler vapour grown carbon nanofiber (VGCNF) with polyvinyl alcohol (PVA) polymer by applying casting technique to form a series of PVA/VGCNF conducting polymer nanocomposites. The fabricated nanocomposite was characterized for identifying the surface morphology with Scanning Electron Microscopy (SEM) technique. The electromagnetic shielding (EMS) effectiveness were obtained using the dielectric parameters (capacitance and dielectric constant dielectric loss and conductivity) to 10 MHz to 1 GHz frequency range. The developed PCNC proves to be cost effective with high flexibility for different medical instruments. The PCNC exhibits excellent EMI shielding properties which makes these instruments electromagnetic compatible (EMC) that seek patient safety in hospital environment.
