The use of wet-spinning and polyelectrolyte complexation to assemble carbon nanotube-gel fibers by injecting a SWNT-biopolymer dispersion into a coagulation bath containing a biopolymer of opposite charge is described by A. J. Granero on page 3759. The ability to spin fibers, and their properties, depend on processing conditions such as polyelectrolyte pH, sonolysis regime, and the order in which the anionic and cationic biopolymer solutions are added.
