静电纺丝技术近几年在制备纳米纤维领域得到了广泛的应用,被认为是批量制备纳米纤维材料最简单有效的方法。本文综述了近几年高压静电纺丝技术制备图案化无机物纳米纤维的纺丝装置和过程,特别详细综述了纺丝过程中纤维直径的变化,利用带电流体动力学(EHD)理论推导出纤维直径变化的运动方程,并对方程进行一定程度的修订,以符合电纺无机物纳米纤维直径的变化;并综述了取向纳米纤维、中空纳米纤维、壳-核结构纳米纤维、纳米线、纳米带、纳米管及多层次结构纳米纤维的构建及其基本性能。最后对电纺制备图案化无机纳米纤维未来发展方向,特别是功能化多层次结构电纺无机纳米纤维制备进行了展望。
Electrospinning technology in recent years in the field of preparation of nanofibers has been widely used, is considered as bulk preparation of nanofiber materials, the most simple and effective method. In this paper, the spinning equipment and process of preparing patterned inorganic nanofibers by high-voltage electrostatic spinning in recent years are reviewed. In particular, the changes of fiber diameter in spinning process are summarized in detail. EHD theory is used to derive fiber Diameter, and the equation was modified to some extent in order to meet the change of nanofiber diameter of electrospun inorganic materials. The effects of oriented nanofibers, hollow nanofibers, shell-core structured nanofibers, nanowires and nanoribbons Construction of Nanotubes and Multilayered Nanofibers and Their Basic Properties. Finally, the future development direction of electrospun preparation of patterned inorganic nanofibers, especially the preparation of functionalized multilayered structure electrospun inorganic nanofibers is prospected.
