Abstract

The invention provides an electrospinning direct-writing closed-loop control method. By means of the control method, the direct-writing jet-flow stability, the micro-nano structure uniformity and thedeposition precision can be improved. A visual detection technology is adopted for making real-time judgments according to the jet flow behaviors and the morphology position of a micro-nano structureand conducting control separately, the jet flow behaviors and the morphology position of the micro-nano structure are adjusted and controlled by means of applying voltage adjustment and motion platform speed and position adjustment respectively, mutual interference is avoided, stable jet for a long time can be maintained, and patterned deposition is achieved.

Description

technical field [0001] The invention relates to an electrospinning direct writing control method, in particular to a visual detection-based electrospinning direct writing closed-loop control method. Background technique [0002] With the development of flexible electronic technology, the precise control of micro-nanostructure has become the focus of research. As a solution manufacturing technology, the electrospinning technology coupled with electro-hydraulic power and jet printing can obtain smaller fibers with a diameter of nanometer level than the traditional jet printing technology. However, the fibers produced by electrospinning are difficult to locate and deposit, and it is difficult to collect them in an orderly manner. At present, as an emerging technology, near-field electrospinning direct writing technology can realize the preparation of fibers of various materials with diameters ranging from a few nanometers to hundreds of nanometers, with high speed and high pre...
