Gelatin/tannic acid nanofibres have been prepared and the effects of production parameters, including high voltage, feeding rate and distance between tip of the needle and collector on the morphology of nanofibres are investigated. The results show that the average nanofibre diameter increases with raising the high voltage values, due to less branching of liquid jet. Increasing the feeding rate leads to an increase in the nanofibre diameter, up to a certain value (0.6-0.8 mL/h). Further increase in the feeding rate value causes the formation of a ribbon-like structure. The increment in the content of tannic acid as a crosslinker increases the viscosity of the spinning solution and the average nanofibre diameters. Also, the tensile strength of crosslinked nanofibres increases as compared to that of the gelatin nanofibres. Moreover, the addition of tannic acid to gelatin nanofibres significantly enhances the antibacterial property of nanofibres.

单宁酸对电纺明胶纳米纤维性能的影响

制备了明胶/单宁酸纳米纤维，研究了生产参数，包括高电压，进料速度和针尖与集电极之间的距离对纳米纤维形态的影响。结果表明，由于液体射流的分支减少，平均纳米纤维直径随高压值的增加而增加。进料速度的增加导致纳米纤维直径的增加，达到一定值（0.6-0.8 mL / h）。进给速度值的进一步增加导致形成带状结构。单宁酸作为交联剂的含量的增加增加了纺丝溶液的粘度和平均纳米纤维直径。而且，与明胶纳米纤维相比，交联纳米纤维的拉伸强度增加。此外，
