Preparation of epoxy/non-metallic conductive filler nanocomposomes.

Scientists have prepared epoxy/non-metallic conductive filler nanocomposing materials and studied their EMI shielding properties.
non-metallic conductive materials, such as intrinsic conductive polymers (ICPs) and carbon nanomaterials, play an important role in the manufacture of conductive polymer nanocomposective materials for electromagnetic interference (EMI) shielding applications. In the study, the electrodynamical, dielexic and EMI shielding properties of epoxy (E)/non-metallic conductive materials were studied

. In order to manufacture conductive epoxy nanocomposites, polyphenylamine (PANI) has been chosen as the most famous carbon nanomaterial for ICP, graphene and multi-walled carbon nanotubes (MWCNT).
composite materials are prepared by solvent mixing. It was observed that both the real and imaginary parts of the dielectric constant increased with the CNT and thermal reduction graphene oxide (TRGO) loads. E / PANI (35%) composites have the highest dielec system loss value, while E / PANI (35%) and E / TRGO (3%) nanocomposomes have the highest dielec meter constants.
higher EMI shielding
in addition, the EMI shielding effect (SE) is higher with high levels of conductive fillers. Maximum reflection losses were observed for E/CNT (2.5%) and E/PANI (15%). In fact, E /PANI (15%) exhibits a relatively wide effective bandwidth of 3.6 GHz (i.e., reflection loss of -10 dB), compared to 2.1 GHz (2.5%) for E/CNT.
the study has been published in Volume 145 of Progress in Organic Coatings.
