Problems solved by technology

However, these relatively mature methods still have great challenges in directional manipulation of microfilaments: ① When spinning a viscous or nearly insulating polymer solution melt or solution, it is difficult to overcome the surface tension to form a jet; ② due to Especially in the high-voltage electrostatic field, the requirements for safety, convenience and energy saving need to be improved; ③The collected alignment spinning tends to be parallel or orthogonal, and it is difficult to collect mesh alignments at various angles

Description

technical field [0001] The invention relates to a microfluid mechanical spinning device, in particular to a microfluid spinning device for preparing ordered and oriented fibers. Background technique [0002] At present, the spinning devices commonly used by manufacturers and research institutes in various countries in the world are mainly electrospinning devices, melt spinning devices, template drawing, etc. The methods used for directional spinning mainly rely on receivers and electric field control. One of the most typical methods: For example, electrospinning is based on the high-speed jet of conductive fluid doped with magnetic nanoparticles under a high-voltage electrostatic field, which is received by two electrodes or a drum receiver to form oriented microfibers; or The receiver adds two electrodes that impart a charge to the spinneret, effectively forming parallel filaments. However, these relatively mature methods still have great challenges in directional manipul...
