Abstract

A method comprising forming and grafting polymers on carbon nanotubes, a functionalized product and product dispersion produced by the method, a method of forming composites from the functionalized carbon nanotubes, and the composites produced therefrom.

Claims (6)

1. A method comprising the step of reacting a monomer material in the presence of a carbon nanotube material such that a polymer product is produced from said monomer material and is chemically bonded to said carbon nanotube material to form a functionalized carbon nanotube product, wherein:

said polymer product is a polyclectrolyte having a charge;

said method further comprises the step of assembling said functionalized carbon nanotube product with a polyelectrolyte material of opposite charge using a layer-by-layer technique to produce a composite product;

said polymer product is poly(sodium 4-styrenesulfonate); and

said polyelectrolyte material of opposite charge is polyethyleneimine or poly(diallyldimethylammonium chloride).

2. A composite product produced by the method of claim 1 .
