Abstract:

In order to obtain optimized structural parameters of melt differential electrospining, finite element analysis software (ANSYS) was employed to simulate and analyze the distribution of the electric field intensity in multiple cone needleless melt differential electrospinning. The influence of design paramenters on the electric field intensity was anslyzed. The effect of inner diameter and extend distance on the electric field intensity distribution of spinning edge and spinning path was discussed respectively. The results indicate that the electric field intensity of the spinning edge was weakened with the increasing cone number, and for double cone needle-free melt differential electrospinning, the influence of inner diameter size on electric field intensity distribution of spinning edge is not obvious. While the extend distance of inner cone increase gradually, the difference value of electric filed intensity between inner and outer cone is found to decrease firstly and then increase. In particular, the electric filed intensity distribution of inner and outer cone is the most similar and the jet spacing of inner and outer cone is almost identical when the inner cone diameter is 26 mm, and inner extend distance is 6 mm. The experimtntal results are consistent with the simulation results.
