Abstract
In order to meet the increasing demand for nanofibers and overcome the
disadvantages of traditional electrospinning technology, it is necessary to
research an electrospinning device that can produce nanofibers efficiently.
In this paper, a free surface electrospinning device was improved, and a
spherical section free surface electrospinning device was developed to
prepare high-quality polyacrylo-nitrile nanofibers in batches. Meanwhile,
MAXWELL 3-D software was used to simulate the electric field distribution of
the spherical section free surface electro-spinning with solution reservoirs
of different spherical radii. The influence of the spherical radius on the
spinning effect was analyzed to study the spinning mechanism. The results
showed that when the applied voltage was 40 kV, the electric field
distribution of the spherical section free surface electrospinning with a
larger spherical radius was more uniform, the nanofiber diameter was
larger, the nanofiber diameter distribution was more uniform, and the yield
of nanofibers was higher. When the spherical radius was 75 mm, the quality
of nanofibers was better, and the yield could reach the maximum value of
14.35 g per hour, due to its higher average electric field intensity and
uniform electric field distribution.
