Description

technical field [0001] The invention relates to a spinning device and method for orderly controlling the ordering of nanofiber molecules, belonging to the field of bubble electrospinning. Background technique [0002] Nanofibers have been rapidly developed in the fields of textile engineering, tissue engineering, filtration, optoelectronic devices, and sensors. Electrospinning technology is one of the most common, simplest, low-cost and high-efficiency methods for producing nanofibers. It is simple to operate and widely used in various fields. Bubble electrospinning is a new type of electrospinning method proposed in recent years. Bubbles are formed by introducing gas into the spinning solution. The bubbles are equivalent to Taylor cones in electrospinning. Tensile rupture forms countless jets, and finally micro- and nanofibers are formed. Bubble electrospinning effectively improves the spinning efficiency. [0003] Synthetic fibers have poor performance compared to natur...
