Abstract

This paper presents a comparative study of electromagnetic interference (EMI) shielding properties of PVDF-PVP composite film with VGCNF as a conducting filler. The films were fabricated using solvent casting and further tested for their mechanical and thermal properties. The process was followed by a comparative analysis of shielding effectiveness calculated via dielectric parameters against the shielding measured through scattering parameters with the help of a network analyzer. Scanning Electron Microscopy was also done to better understand the morphological structure of the films. The film, with a thickness of around 0.18 mm, showcased shielding effectiveness within 25 dB-34 dB across a frequency band of 12 GHz to 18 GHz while being flexible and mechanically durable.
