Morphology,Microstructure and Dielectric Properties of Polymer-Based Composite Nanofibers via Electrospinning
1.Introduction Electrospinning is a simple, versatile and useful technology for fabricating ultrafine fibers ranging from micrometers down to 100 nm or less in diameters, from a rich variety of materials such as biological polymers, engineered polymers, ceramics, carbons, and composites. However, the electrospun nanofibers by the typical method are usually in the form of non-woven mats, which limits a few practical applications. Recently, several groups have attempted to improve the typical method of electrospinning in order to obtain aligned nanofibcrs1,2. In addition, dielectric properties of electrospun composite nanofibers have not been reported intensively. In this paper, we report several kinds of polymer-based composite nanofibers prepared by electrospinning, for example, ZrOCl2/PVA3, Mn(CH3OO)2/PVP, Zn(CH3OO)2/PVP, and TiCH3(CH2)3O4/PVP composite nanofibres, and study their morphology, structure and dielectric constant as a function of frequency and pressure. In addition, we have obtained partly aligned electrospun nanofibres by sidestep collection and two-parallel-collector method successfully.
