离心静电纺丝法制备有序、交叉以及绞线结构的荧光纳米纤维
Fabrication of Fluorescent Nanofibers of Aligned Arrays, Two-Layer Grid-Patterns and Nanoropes via Electrospinning
【摘要】 利用新型低压离心静电纺丝法制备了有序排列、交叉排列以及绞线结构的荧光纳米纤维(掺杂荧光物质为荧光素和罗丹明B)。利用扫描电镜(SEM)、荧光显微镜和荧光光谱仪对纤维的微观形貌和荧光性质进行了表征和测量,结果显示,绞线结构的荧光强度较单根纤维组合大大加强。
【Abstract】 Fluorescein/PMMA and rhodamine B/PS composite nanofibers acting as aligned arrays,two-layer grid-patterns and nanoropes were preparaed via electrospinning,respectively.The morphology and the fluorescence were observed by SEM,fluorescence microscope,and fluorescence spectrum techniques.Results show that the fluorescence intensity of the nanoropes is much higher than that of assemble of individual nanofibers.
