Abstract: Carbon nanotubes as fillers in an epoxy matrix for mechanical reinforcement and heat diffusion enhancement are tested. We demonstrate a method to covalently graft functional molecules on carbon nanotubes to alter the filler/matrix interface incompatibilities, making the carbon nanotubes become soluble in epoxies and allows better homogenisation of the fillers in the matrix. As a result, the carbon nanotubes will bond to the epoxy matrix during polymerisation, and thus create a better mechanical strength and heat transfer enhancement.
Keywords: carbon nanotubes; functionalisation; epoxy composites; n-butyllithium; nanotechnology; mechanical reinforcement; heat diffusion enhancement; polymerisation.
