Nonstoichiometric TiN 1+ x ( x = 0–0.26) nanofibers have been successfully fabricated by electrospinning versus ammonification process. Electrical properties of TiN 1+ x nanofibers were investigated with respect to the stoichiometric deviation degree x . The electric conductivity of the TiN 1+ x nanofiber reached as high as 121.1 S/cm with x = 0.03. When stoichiometric deviation degree increased, the electric conductivity decreased and nonlinear I – V character was shown in these TiN 1+ x nanofibers. The nonohmic electric characters of the nonstoichiometric TiN 1+ x nanofiber prepared by electrospinning combined with ammoniation demonstrated a promising candidate of one‐dimensional material applied in electric devices such as varistors or microswitch.
