Abstract

Nanoclay was used as a support material to grow nanotubes on the surface of clay by reduced-pressure chemical vapor deposition (CVD). The addition of 2 wt. percent nanoclay-supported carbon nanotubes into the epoxy matrix led to a 40 percent improvement in the Vicker's hardness of the composites. The nanotubes prepared are protected from aggregation by the interlayer space of nanoclay. The considerable improvement is attributed to the in situ growth of nanotubes on nanoclay layers, which allows for the separation of nanotubes, the exfoliation of nanoclay in the polymer matrix, and the possibility for mechanical interlocking to occur within the matrix.
