Conteúdo: 	Carbon nanofbers (CNF) are highly electric conductor materials that can be produced from petroleum-based polymers by diferent methods, such as electrospinning and solution blowing (SBS). In this work, we studied the production of CNF by SBS from lignin. The nanofbers were characterized by XRD, FTIR, Raman and 13C solid state NMR spectroscopies, thermogravimetry (TG / DTG), diferential scanning calorimetry (DSC), and their structural properties were assessed by scanning electron microscopy (SEM). CNF were obtained with a PAN/lignin ratio up to 20:80 from solutions with mass concentration of 18%. For the 10:90 PAN/lignin ratio, nanofbers were only obtained from solutions with constant viscosity of 0.2 Pa.s. The nanofbers had an average diameter of 228.5 nm and R (ID/IG) of 1.26. Thus, carbon nanofbers with up to 90% lignin were successfully produced in this work using the new solution blow spinning technique
