静电纺丝纤维束的制备及其应用

Preparation and Application of Electrospun Fiber Bundles

静电纺丝是一种简单、快捷制备亚微米、纳米级纤维的新技术。当纤维的直径由微米级下降至亚微米级甚至纳米级时,就会呈现许多优异的性能,如较大的比表面积、较强的韧性及优异的力学性能等。综述了近年来静电纺丝技术制备取向的纳米纤维束及纤维束的性能。

Electrospinning is a simple and effective method to obtain submicron and nanometer scale polymer fibers. When the diameters of polymer fibers are shrunk from micrometers to submicrons or nanometers, there appear several amazing characteristics, such as very large surface area to volume ratio, flexibility in surface functionalities and superior mechanical performance. The development of preparing aligned electrospun nanofiber bundles and their mechanical properties are summarized.
