839-842. reports a kind of electrospinning direct-writing patterned nano-fiber structure.Although the method is obtained in that list
The direct write deposition of root fiber arbitrary graphic, but its efficiency is the lowest, it is impossible to realize nanofiber the most industrial
Metaplasia is produced.Document Theron A, Zussman E, Yarin AL.Electrostatic field-assisted
alignment of electrospun nanofibres[J].Nanotechnology,2001,12:
Half top that in 384-90., A.Theron etc. process with the conductive aluminum disk edge of diameter 200mm thickness 5mm
Angle is that the equilateral wedge angle of 26.6 ° is as collecting nanofibers device.After applying electric field, the electric field line on drift angle is close
That spends than on other position is much bigger so that the nanofiber almost all of injection is drawn to top by electric field force
