METHOD OF PREPARING ARAMID POLYMERS INCORPORATING CARBON NANOTUBES.

摘要

The invention relates to a method of preparing an aramid polymer solution having carbon nanotubes dispersed therein, providing a first dispersion comprising carbon nanotubes and a carrier polymer in a first solvent; providing a first solution comprising an aromatic diamine having an electron affinity lower than that of the carrier polymer and, optionally, a second solvent; adding the first solution to the first dispersion to form a second dispersion; adding an aromatic diacid or aromatic diacid chloride to the second dispersion; polymerizing the aromatic diacid or aromatic diacid chloride with the aromatic diamine to form a carbon nanotube containing aramid polymer or co-polymer in a first aramid solution; isolating the carbon nanotube-containing aramid polymer or co-polymer; and dissolving the carbon nanotube-containing aramid polymer or co-polymer in a third solvent to form a second aramid solution.
