探针阵列诱导构建三维电纺纳米纤维结构分析(英文)

三维纳米纤维结构具有超高比表面积、可控孔径和孔密度,潜在应用非常广泛.以高度和位置可调的探针阵列为静电纺丝收集器,同时探针阵列通过控制开关与辅助电压相接,通过改变各探针高度、探针间距和与辅助电压的导通状态,制备所需的三维纳米纤维结构.初步实验结果表明,最大/最小探针间距随着电压的增大而减小,而随喷头与收集器间距的增大而增大.同时,增大探针高度差或减小喷头与收集器间距/探针间距将导致辅助电压变大.

Construction and Analysis of Probe Array Induced 3D Electrospun Nanofiber Structure

Three-dimensional（3D） nanofiber structure has vast potential applications due to its large surface area to volume ratio, controllable pore diameter and pore density. Probe array with adjustable height and position, which is controlled by switch controller to be connected with auxiliary voltage, is utilized as electrospinning collector. Desired 3D nanofiber structure can be fabricated by changing indi- vidual probe height, probe-to-probe distance and connectivity with auxiliary voltage. The preliminary experimental results show that the maximum/minimum of probe-to-probe distance decreases with the in- crease of applied voltage but increases with the increase of spinneret-to-collector distance. Meanwhile, auxiliary voltage decreases as spinneret-to-collector distance and probe-to-probe distance increase, but increases with the increase of height difference.
