Abstract

The invention discloses a method and system for in-situ coating of electrospinning nanofiber film on the surface of a material. The system comprises an injector unit, a high-voltage electrostatic generator unit and a collecting device, wherein the injector unit and the collecting device are connected with the positive pole and negative pole of the high-voltage electrostatic generator unit respectively, the injector unit and/or the collecting device are/is also connected with a drive and transmission device, and the drive and transmission device is at least used for driving the injector unit and/or the collecting device to freely move in the selected direction. The method comprises the step that through the control of the high-voltage electrostatic generator unit, the drive and transmissiondevice and a rotating device, an electrospinning solution forms the electrospinning nanofiber film in situ on the surface of the to-be-coated-in-situ material through an electrospinning technology.
