静电纺丝领域的主导研究是研究聚合物浓度和链长度等参数，以确定聚合物链充分缠结以促进纤维形成的条件。在这里，我们首次报道了可以使用传统的单喷嘴装置将线性、非缠结的低聚电解质电纺成纤维。此前，我们已经证明，称为复合凝聚的缔合相分离现象有利于直接从水中静电纺丝聚电解质复合纤维。在这项工作中，我们合成了聚合度从 500 到 500 的聚阳离子和聚阴离子。
The electrospinning field is dominated by studies that investigate parameters, such as polymer concentration and chain length, to identify conditions where the polymer chains are sufficiently entangled to facilitate fiber formation. Here, we report the first demonstration that linear, nonentangled, oligomeric polyelectrolytes can be electrospun into fibers using a traditional single-nozzle setup. Previously, we have demonstrated that the associative phase separation phenomenon known as complex coacervation facilitates the electrospinning of polyelectrolyte complex fibers directly from water. In this work, we synthesized polycations and polyanions with degrees of polymerization ranging from similar to 500 down to
