Abstract Cellulose was dissolved with ionic liquid 1,3-dimethylimidazole dimethyl phosphate [MMIM]+[MMP]-, and added electrolyte to obtain spinning liquid with different conductivity. Carbon fiber was prepared by electrospinning method, and characterized detailedly to study the surface structure, chemical state, thermal decomposition and its stability, surface morphology, and conductivity properties. The results showed that the carbonization yield, conductivity, and dimensional uniformity were effectively improved by adding electrolyte, and the optimum adding amount of LiCl and carbonization temperature were 1.2wt% and 900 ℃, respectively. This study provides new solution to prepare high quality carbon fiber on a large scale by electrospinning method.
