The electrostatic spinning technology is the most common and simple method for producing the nano-fibers with low cost and high efficiency, is simple to operate and is widely applied to various fields. Bubble electrostatic spinning is a novel electrostatic spinning method proposed in recent years, and gas is introduced into spinning solution to form bubbles, the bubbles are equivalent to Taylor cones in electrostatic spinning, and the bubbles are gradually stretched and broken under the action of electric field force or airflow to form countless jet flows, and finally micro-nano fibers are formed. The bubble electrostatic spinning can effectively improve the spinning efficiency.
Compared with natural fibers such as spider silk, the artificially synthesized fibers have poorer performance. Many natural fibers such as spider silk or silk have good hierarchical structures, and micro/nano fiber molecular structures generated by electrostatic spinning or bubble spinning do not have folding symmetry and do not have the hierarchical structures of the natural fibers. Artificially synthesized fibers having a nano-scale hierarchical structure can exhibit many excellent characteristics of materials, which cannot be realized by a non-hierarchical structure. In order to improve mechanical properties, electronic properties, chemical properties, and the like of nanofibers, it is very important to improve the molecular orientation of nanofibers. Molecular motion during spinning or molecular orientation in nanofibers remains a problem to be studied. To date, it has been almost impossible to control the orientation of the molecules during spinning. If the spinning process can be controlled on a macro-molecular scale to improve the crystallinity, the method has important significance for controlling the fiber form and adjusting the mechanical, electronic and chemical properties of the fiber.
