Near Field Direct Wiring Electrospinning Equipment M08

PRINCIPLE OF NEAR-FIELD ELECTROSPINNING 

In 2006, QINGZI group firstly developed the techniquqe of near-field electrospinning. Precisely ordered and highly oriented nanofiber arrays were  prepared when the collector was placed 0.5-5 mm to the nozzle and the motion of  these two parts was precisely controlled.

NEAR-FIELD ELECTROSPINNING TECHNOLOGY

Solution near-field electrospinning

Printing materials were firstly dissolved in solution. During the near-field electrospinning process, the solution jet  was stretched by the electrostatic repulsion, and fibrous products with diameter range from 50 nm-20 μm could be  collected. Fibrous products prepared through this technique are highly applicable.

Melt near-field electrospinning

Printing materials were firstly melted by heat treatment. During the melt near-field electrospinning process, the molten  fluid was stretched by the electrostatic repulsion, and fibrous products with diameter range from 500 nm-50 μm could be  collected. Fibrous products prepared through this technique are suitable for the fabrication of 3D bio-scaffold.
