Description
Summary:The poly (vinylidene fluoride) (PVDF)/ N, N-dimethylformamide (DMF) solution was taken for example to fabricate insulated membrane by electrospinning in this paper,. It was found experimentally that in the process of electrospinning, the area of membrane collected was bigger and bigger and the fiber diameter was increasing from the bottom to the surface, but the fiber diameter of every layer was uniform. The reason was analyzed in this paper, and it was considered that in the electrospinning process, the positive charges accumulated on the insulated membrane changed the electric field distribution. As a result, the area increased and the weakened electric field intensity increased the fiber diameter.
