Abstract

Composites based on commercial thermoplastic polyurethane resin (PU) with three different types of carbon nanotubes (CNT), in 0.5% concentration, were prepared and applied on an AA 7075 aluminum surface. CNT unfunctionalized, CNT functionalized with carboxylic groups, and CNT functionalized with amine groups were tested. The composites were evaluated by optical microscopy, adhesion, impact strength, salt spray, and electrical conductivity. In addition, a wave-guide technique between 8.2 and 12.3 GHz was used to measure the electromagnetic properties of the composites. The results showed that the CNT functionalized with amine group (NH2) presented a good interaction of the PU resin, thus forming a level and uniform film. The analyses of adhesion, direct impact, and salt spray showed that all samples presented excellent performance. Although the samples presented a low electromagnetic performance, an emerging potential for electromagnetic shielding was noticed.

Keywords: aluminum; carbon nanotubes (CNT); composites; electromagnetic properties; polyurethane (PU) resin
