Abstract

Carbon nanomaterials have been an attractive topic within diverse industrial sectors given their outstanding properties for decades. One of the properties that has been calling attention is it’s shielding effectiveness (SE) for electromagnetic interference (EMI), because of the constant race of improving portable electronic and wireless communication devices among other applications. The present study, analyzes the properties of interlaminated Carbon Nanofiber (CNF) mats/Carbon Nanotubes (CNT) polymer composites, emphasizing in its capability to shield EMI. The CNF mats were developed with Polyvinyl alcohol (PVA) as a precursor and by means of the Forcespinning® technology which uses centrifugal force to create fibers in the nanoscale. The non-woven PVA mats were subjected to a dehydration process which then would be followed by a heat treatment resulting in the CNF mat. The mats were heat pressed together with the CNT polymer composite to create a flexible laminate of roughly .5 mm thick. The final product consists of 4-8 laminates being pressed together, becoming a material exposing enhanced electrical conductivity and EMI SE capabilities.
