Research on Electrospinning of Cellulose Acetate Prepared by Acetone /DMAc Solvent

Electrospinning is a technique that can be used to produce nanofibres from a polymeric solution or melt under the influence of a high electrostatic field [. In this paper, we used Acetone/N, N-Dimethyl acetamide (DMAc) and Acetic acid as the solvent, to explore the influencing factors of using electrospinning to prepare the nanofiber of cellulose acetate, and studied on how solvent, voltage and viscosity impact on the morphology and diameter of nanofiber. The results of the study show that: Acetone/DMAc as solvent, when the solvent ratio is 3:1, the spinning of the concentration is 4%～6%, the viscosity is 7.1～8.3 Poise, the voltage is 15kV, and deposition distance is 12cm, we could obtain the gelatin nanofibers with the diameter of 200-300 nanometer prepared by electrospinning. This study provided the theoretical basis for cellulose acetate prepared by electrospinning in antimicrobial food packaging materials development.
