Polymers grafted to carbon nanotubes
View Patent ↗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.
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 .
