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.
The three-dimensional nanofiber structure has very high specific surface area, controlled pore size and pore density, and has a wide range of potential applications. The probe array with adjustable height and position is an electrostatic spinning collector, and the probe array is controlled by controlling the switch and the auxiliary voltage phase Then, the desired three-dimensional nanofiber structure was prepared by changing the probe height, probe spacing and conduction state with auxiliary voltage.The preliminary experimental results show that the maximum / minimum probe spacing decreases with the increase of voltage , And increases with the increase of the distance between the nozzle and the collector, and at the same time, increasing the height difference of the probe or decreasing the distance between the nozzle and the collector / probe will lead to the increase of the auxiliary voltage.
