Electrospinning is a simple and versatile technique that relies on the electrostatic repulsion between surface charges to continuously draw nanofibers from a viscoelastic fluid. It has been applied to successfully produce nanofibers, with diameters down to tens of nanometers, from a rich variety of materials, including polymers, ceramics, small molecules, and their combinations. In addition to solid nanofibers with a smooth surface, electrospinning has also been adapted to generate nanofibers with a number of secondary structures, including those characterized by a porous, hollow, or core–sheath structure. The surface and/or interior of such nanofibers can be further functionalized with molecular species or nanoparticles during or after an electrospinning process. In addition, electrospun nanofibers can be assembled into ordered arrays or hierarchical structures by manipulation of their alignment, stacking, and/or folding. All of these attributes make electrospun nanofibers well-suited for a broad spectrum of applications, including those related to air filtration, water purification, heterogeneous catalysis, environmental protection, smart textiles, surface coating, energy harvesting/conversion/storage, encapsulation of bioactive species, drug delivery, tissue engineering, and regenerative medicine.

电纺纳米纤维：新概念，新材料和新应用

电纺丝技术是一种简单而通用的技术，它依赖于表面电荷之间的静电排斥力来从粘弹性流体中连续提取纳米纤维。它已被用于从多种材料（包括聚合物，陶瓷，小分子及其组合）成功生产直径低至数十纳米的纳米纤维。除了具有光滑表面的固体纳米纤维之外，静电纺丝还适用于产生具有许多二级结构的纳米纤维，包括以多孔，中空或芯鞘结构为特征的二级结构。这种纳米纤维的表面和/或内部可以在静电纺丝过程中或之后用分子种类或纳米颗粒进一步功能化。此外，电纺纳米纤维可通过操纵其排列，堆叠和/或折叠而组装成有序的阵列或分层结构。所有这些属性使电纺纳米纤维非常适合广泛的应用，包括与空气过滤，水净化，多相催化，环境保护，智能纺织品，表面涂层，能量收集/转化/存储，生物活性物质包封有关的那些，药物输送，组织工程和再生医学。
