    • A method for the production of an array of aligned fibres by electrospinning, which comprises forming a focused electrostatic field between a body having an orifice, maintained at a first electric potential, and a counter electrode, maintained at a second electric potential, the modulus of said second electric potential being greater than the modulus of said first electric potential, introducing a solution of a polymer in a volatile solvent into the electrostatic field through the orifice such that the polymer solution flows from the orifice towards the counter electrode in the form of a charged jet or stream, said jet or stream having a path length at least a portion of which is substantially straight, disposing a collector means in the path of the jet or stream at a position within the substantially straight portion thereof at which the solvent has evaporated sufficiently for the jet or stream to solidify, and moving the collector means relative to the jet or stream to deposit aligned fibres on the collector means.
    • 一种用于通过静电纺丝制备排列的纤维阵列的方法,其包括在维持在第一电位的具有孔口的主体和保持在第二电位的对电极之间形成聚焦的静电场, 所述第二电位大于所述第一电位的模量,将聚合物在挥发性溶剂中的溶液通过所述孔引入静电场,使得所述聚合物溶液以所述孔的形式从所述孔向所述对电极流动 所述射流或流具有其至少一部分基本上直的路径长度,将收集器装置设置在射流或物流的路径中,其位置处于溶剂蒸发的基本上直的部分内 充分地使射流或流固化,并使收集器相对于射流或流移动以沉积对准 d纤维在收集器上。
