摘要
Hierarchically structured polymer fibers encompassing 1-D, 2-D, and 3-D structures with at least one dimension nano- to micro-meters in size have recently received an increasing amount of attention due to their vast potential in such applications as sensing, medicine, energy storage. This review summarizes advancements in the last ten years in the design and fabrication of hierarchically structured polymer fibers via electrospinning technologies, including a diversity of electrospinning devices and electrospinning parameters using various polymers. These well-defined, multilevel structures enable the fibers to be used more effectively in applications in the biomedical field, such as drug delivery, tissue engineering, and diagnostics. This review can provide a better understanding of the relationships between the structure and functionality of polymer fibers for further biomedical applications. (C) 2017 Elsevier B.V.
