DEVELOPMENT OF FUNCTIONALIZED GRAPHENE-PEEK MATRIX NANOCOMPOSITES

摘要

Poly(ether ether ketone) (PEEK) is a high performance engineering polymer used in aerospaceand military industry. PEEK is a tough aromatic thermoplastic polymer with excellentmechanical properties, thermal stability and abrasion and solvent resistance. To expand its rangeof applications, several studies have focused on the production and characterization ofnanocomposites. Functional nanocomposites have gain interest in the last decade since thediscovery of fullerenes and carbon nanotubes. The addition of functional nanofillers allows thereinforcement of a polymeric matrix with low loadings of fillers, improving other properties ofthe matrix. Nowadays graphenes have become the state-of-art in carbonaceous nanofillers.Graphenes are produced by thermal expansion of graphite oxide (GO) leading to high surfacearea carbon materials consisting of atomically thick functionalized graphene sheets (FGS) withextraordinary thermal and mechanical properties which make them ideal to improve theremarkable properties of PEEK. This paper is focused on the processing and characterization ofPEEK/grapheme nanocomposites for increased mechanical and functional properties.
