Microwave Absorption Performance of Flexible Porous PVDF-MWCNT Foam in the X-Band Frequency Range.

ABSTRACT: Lightweight electromagnetic absorbers made of polymers and multiwall carbon nanotubes (MWCNTs) have attracted a lot of attention because of their potential to shield next-generation electronics devices from electromagnetic radiation without reflecting it back into space. In this research, a flexible foam composed of MWCNTs and polyvinylidene fluoride (PVDF) is developed. This foam is designed to be an electromagnetic shielding material that is both flexible and absorption-dominant, reducing electromagnetic interference. The solvent approach is used to fabricate the PVDF-MWCNT foam. It is discovered that the foam has a porosity of 88.9%. Each cell in the PVDF-MWCNT foam is formed in a porous layered manner. The foam demonstrates a dielectric constant (ϵ ^' ) of around 7.19
