Title:
PROCESS FOR THE CONTINUOUS, LARGE-SCALE SYNTHESIS OF CARBON NANOTUBES ON CEMENT CLINKER, AND NANOSTRUCTURED PRODUCTS
Document Type and Number:
WIPO Patent Application WO/2009/132407
Kind Code:
A3
Abstract:
The present invention describes a chemical vapour deposition method for the synthesis of carbon nanotubes, in which method cement clinker is used as a ceramic matrix to catalyse the process or to anchor transition metal nanoparticles. The use of cement clinker as a substrate to anchor transition metal nanoparticles allows the generation of carbon nanotubes on particles and grains of cement clinker, and thus allows the production of a type of nanostructured cement with carbon nanotubes in which the synthesis and integration of carbon nanotubes in the clinker are performed in a single continuous step on a large scale. The invention also proposes, as part of the process of synthetising carbon nanotubes on cement clinker, various options to enrich the latter with transition metals in order to integrate optionally the production of said nanostructured composite into the conventional cement industry.
