Polymers and High Performance Materials


The development of high-power electromagnetic wave sources in the modern era has the ability to interfere with aircraft electronics and cause localized heating – necessitating advanced materials for electromagnetic interference (EMI) and thermal shielding. Multifunctional nanoparticles dispersed within polymer matrices can combat these issues; however, the best way to combine thermally and electrically conductive species to maximize electromagnetic interference shielding and thermal shielding is undetermined. Multifunctional layered epoxide/amine nanocomposites were prepared from tetra and octafunctional epoxide monomers (TGDDM and SU-8), 4,4-DDS tetrafunctional amine curative, and 1 wt.% hexagonal boron nitride nanoplatelets and/or 1 wt.% graphene nanoplatelets to form monolayer and bilayer films. Multilayer, vitrified nanocomposite laminates were prepared and characterized to quantify particle dispersion, layer orientation/integrity, rheological properties, and thermal properties via optical/scanning electron microscopy, FTMS rotational rheometry, thermogravimetric analysis, and laser flash diffusivity analysis. Monomer conversion throughout various cure profiles was quantified using ATR-FTIR spectroscopy. The data collected indicated that discrete layers were maintained throughout thermoset curing, with no hindrances in the rheological or thermal properties of the matrix. This suggests a new methodology for preparing layered, multifunctional EMI/thermal shielding materials with enhanced thermal conductivity.
