Micro nano structure direct-writing device

Abstract

The invention relates to a micrometer-nanometer structure writer of polymer material, wherein it is based on near-field static spinning technique, to quickly write adhesive material or macromolecule material, while the minimum diameter / line width is lower than 300nm / 20 mum. It has micro probe control platform, integrated high-voltage static power source, flux controller, X-Y platform, probe and CCD microscope; the integrated high-voltage static power source can power the probe, while its anode is connected to probe and cathode is connected to ground; the flux controller is fixed on the micro probe control platform, while it is connected to probe via tube; the probe is used as ejector of material, while it is mounted on micro probe control platform; the microscope is used to detect the spinning process and the writing effect, while it is arranged on micro probe control platform.

Description

technical field [0001] The invention relates to a device for direct writing of micro- and nanoscale materials or patterns based on electrospinning technology, in particular to a direct-writing device for polymer materials with submicron line width. Background technique [0002] In the research and development of micro-nano devices, the integration of nanowires, nanotubes, nanofibers and microstructures (such as microelectrodes) with controllable position, direction and quantity is the key to manufacturing nanodevices such as The key to nanosensors and actuators.

Problems solved by technology

The current material jet printing head is still based on the traditional inkjet printing head technology, the smallest droplet is about 10pl, and the smallest line width is 50μm. It is very difficult to further reduce the line width, which greatly limits the application range of this technology.
