Results: The differences of different types electrospinning machines are compared
and analyzed and the characteristics are concluded. The main problems in its development are analyzed,
the development trend is foreseen, and the current and future developments of the patents on electrospinning
machine are discussed.
Conclusion: The optimization of the electrospinning machine structure improves the efficiency of spinning
and the electrospinning condition. For further enhancement, more patents on electrospinning machine
should be invented.
