Solid state ball milling: Path to optimised dispersion of multifunctional nanofillers

Research output: Contribution to specialist publicationArticle

Abstract

A new efficient, solvent-free compounding method, solid state ball milling (SSBM), has been identified as a viable new processing method for nanocomposites which succeeds in simultaneously lowering the percolation threshold and achieving excellent mechanical properties. Polyetherimide (PEI) nanocomposites reinforced with exfoliated graphite (graphene) nanoplatelets (GNP) were fabricated by various processing methods to achieve good dispersion including: melt-extrusion, solid state ball milling (SSBM) as well as combinations of these methods. SSBM was investigated as an alternative process to enhance dispersion, adhesion and to reduce GNP size. High electrical conductivity was achieved by this approach as compared to melt-extrusion. Further improvements of the mechanical properties could be made by combining the extrusion and SSBM approaches. Examination of the nanocomposite morphology explains the effect of these combined compounding approaches on GNP particle dispersion and their relation to the improved GNP/PEI nanocomposite performance.
