摘要

Attention has recently become focused on the performance advantages of nanocomposites, and particularly polymer-based nanocomposites with respect to incumbent neat polymers or metallic materials for lightweighting initiatives. In the interest of sustainability, the specific use of bio-reinforced nanocomposite parts and nanostructured coatings within automotive, aerospace, construction, medical and packaging applications is accelerating. These green nanocomposites can provide high mechanical strength at low density, low weight, and low cost while generating low carbon dioxide emissions. However, there are interfacial surface adhesion challenges with these and other nanocomposites, in addition to particle distribution and stability issues, which can inhibit full realization of their mechanical performance advantages. This paper will profile polymeric nanocomposites and nanocoatings, as well as define surface modification protocols using atmospheric pressure plasma technologies to optimize interfacial adhesion to similar and dissimilar materials.
