Patent ID: 7935767

Claim:
A method for dispersing a population of carbon nanotubes comprising: (a) providing a solution of multiblock polymers; (b) contacting a population of carbon nanotubes with the multiblock polymer solution of step (a) to disperse the carbon nanotubes; and (c) optionally recovering the dispersed carbon nanotubes wherein the multiblock polymers have the formula: (R 2 ) a —[(R 1 ) y —(R 2 ) x ] z —(R 1 ) b and wherein: R 1 is benzylmethacrylate; R 2 is methacrylic acid or salt thereof; x is an integer ranging from 1 to 15; y is an integer from 1 to 25; z is an integer ranging from 1 to 13; a is an integer from 0 to 15; and b is 0 or y.
