Abstract

The invention relates to a device capable of eliminating electrostatic influence and used for electro-spinning direct writing and belongs to the field of electrospinning. The device mainly comprises amain channel, a three-dimensional motion platform, a dispensing nozzle, an ion wind nozzle, a plastic hose, an ionizer, a heater, and a controller. A customized gear plate is supported by the upper end of the outer wall of the main channel through a bearing and a spring buckle. The customized gear plate is rotated by a synchronous motor and a synchronous belt. An ionized wind is sprayed towards the front of the spinning path by the ion wind nozzle, under the control of a rotary key, a connector, a rack, the customized gear plate, the synchronous belt, and the synchronous motor. The device capable of eliminating electrostatic influence and used for electro-spinning direct writing neutralizes the charge on a fiber with the ionic wind so as to reduce or eliminate the influence of electrostatic repulsion; the ion wind is sprayed obliquely forward relative to the nozzle through a nozzle structure and the controller without affecting the electrospinning process. Thus, by using this device,the static repulsion can be reduced without increasing the variable to achieve precise positioning.

Description

technical field [0001] The invention relates to a device for electrospinning direct writing capable of eliminating the influence of static electricity, which belongs to the field of electrospinning. Background technique [0002] In recent years, with the continuous development of science and technology and the deepening of research, micro-nano technology has gradually penetrated into all aspects of daily life. Two-dimensional (2D) nanostructures (such as nanofiber mats, nanowires, nanobelts, etc.) It has unique properties such as small size effect, surface or interface effect, superparamagnetism, etc., and has a wide range of applications in many fields. Compared with 2D micro-nanofibers, three-dimensional micro-nanostructures have attracted extensive attention from scholars because of their significantly improved thickness. [0003] The traditional three-dimensional micro-nano structure preparation methods mainly include compression molding, laser microtechnology, photolit...
