PRINCIPLE OF NEAR-FIELD ELECTROSPINNING
In 2006, the QINGZI group firstly developed the technique 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 Electrospinning Technology Classification
Solution Near-field Electrospinning
Solution near-field electrospinning process, the printing material is prepared into a solution and using electrostatic field print orientation nanofibers.
