Byrne et. used cellulose to blend with lignin because cellulose, like lignin, is widely available; therefore, replacing synthetic polymers with cellulose in a lignin-polymer blend will yield a much cheaper carbon fiber. For the experiment, a 20:80 lignin-cellulose blend was prepared (i.e., 20 parts of organosolv lignin and 80 parts of cellulose). With [DBNH]OAc acting as an antisolvent, the blend was spun into precursor fibers via the dry jet wet spinning.
