Organic derivatization of single-walled carbon nanotubes by clays and intercalated derivatives

Single-walled carbon nanotubes were derivatized by the catalytic action of aluminosilicate minerals. Hydrothermal treatment of carbon nanotubes with clay and an aliphatic acid gave side alkylated carbon nanotubes-clay composites, which could be of value in various technological applications. XRD pattern indicates that alcylated carbon nanotubes are intercalated between the clay layers. Following acid demineralization, functionalized carbon nanotubes were obtained and characterized.
