摘要：

Heteroaggregation is employed in a controlled way to the mass-production of individually alumina-decorated multi-walled carbon nanotubes (CNTs) with optimized and controlled compositions, with the aim of obtaining reinforced homogeneously dispersed CNT-alumina matrix nanocomposite after spark plasma sintering. The homogeneous composites can only be obtained for CNT concentrations in the range 2.4-16 vol.%. Irreversibility of decoration is examined, and homogeneity of the composite is further investigated, based on supernatant transparency proposed in our approach. (C) 2008 Acta Materialia Inc.
