Nanofibers are widely used in a range of material applications, such as filter media, biosensors, military protective coatings, three‐dimensional tissue scaffolds, composites, drug delivery, wound dressings and electronic devices. To fabricate nanofibers with desired physical and chemical functions, a variety of electrospinning processes have been introduced using specially designed collectors, microelectromechanical system (MEMS) nozzle tips and auxiliary electrodes to stabilize the spin jets. However, the development of new electrospinning processes continues in the search for ‘tailor‐made’ nanofibers, in which parameters such as the fiber orientation and three‐dimensional structure are ultimately controllable. This paper discusses recently suggested electrospinning methods that are designed to impart specific functionality. It also details the correlations between applied processing parameters and the obtained physical properties of electrospun fibers. Finally, future design directions are suggested for developing an electrospinning apparatus capable of producing optimally structured nanofibers. Copyright © 2007 Society of Chemical Industry 相似文献

Mg0.2Co0.2Ni0.2Cu0.2Zn0.2O high entropy oxide (HEO) with outstanding cycling stability and high capacity retention indicates it is a promising anode material for rechargeable lithium-ion batteries. Rock salt HEO nanofiber has been prepared by electrospinning method. Polyacrylonitrile polymer facilitates the formation of nanowire morphology. The effect of calcination temperature on the phase composition and microstructure evolutions has been investigated. Pure rock salt phase can be obtained after firing at 850°C for 2 min. Calcination at higher temperature than 850°C will break the fiber into short segments and lead to the growth of grain. A reversible capacity of 365 mAh g−1 was achieved after 300 cycles at .2 A·g−1. 相似文献

The fast developing electronic industry boosts higher demand of transparent electrode. Nanofiber network design provides a new platform for finding alternative materials to replace the traditional indium-doped tin oxide (ITO) film as transparent electrode. In this work, the TiN nanofiber network with a micron-scale precise geometry was firstly assembled by solution electrowriting. Unlike the ordinary opaque TiN film or bulk, the geometry patterned TiN nanofiber network achieved an ultrahigh transparency above 90%. Due to the electrical conductive virtue of TiN, the network reached a relatively low sheet resistance of 10.3 Ω/sq that can be comparable to ITO and even metal nanofibers. The combination of high transparency and low sheet resistance in TiN nanofiber network paves a way for its application as transparent electrode. Moreover, the figure-of-merit of TiN nanofiber transparent electrode was controllable by simply adjusting the geometry size of TiN nanofiber pattern. A series of oxidation resistance and corrosion resistance tests were additionally carried out, which caused little effect on the performance of TiN nanofiber transparent electrode. This excellent antioxidative and anticorrosive property demonstrates the high chemical durability of TiN nanofiber network, especially compared to metal nanofiber networks. 相似文献
