静电纺丝技术作为制备纳米纤维的关键方法，其原理是通过高压静电场将纺丝液转化为纤维，凭借独特优势在相关领域备受关注。然而，这项早在三十年 前就已被提出的技术，长期以来面临着产业化的瓶颈——多数研究成果仅停留在实验室阶段，规模化稳定生产始终难以实现。 现在每年有上千篇关于静电纺纳米纤维技术的论文发表，但这些论文更多聚焦于理论研究，并没有真正走出实验室。从实验室到工厂生产线，中间需要跨 越一条颠覆性鸿沟。这一行业痛点精准道出了技术转化的核心难题。在实验室研究中，静电纺纳米纤维生产设备通常仅配备几十到几百个纺丝喷头，不仅 生产的纳米纤维膜幅宽狭小，也极大限制了其应用场景的拓展。而产业化生产的要求更为严苛：既要实现纳米纤维膜的大幅宽、大规模产出，还必须满足 连续稳定、低成本、高质量的生产标准。 没有现成的经验可借鉴，科研团队只能"摸着石头过河"，甚至在多数时候"没有石头可摸"。科研团队在实验室里反复翻阅行业前沿科研论文，不断调整工 艺关键参数，喷头数量也从最初的几十个、几百个、几千个，逐步迭代至一万个的规模。经过无数次的试验与优化，团队最终攻克了万针级连续稳定生产 的行业难题，成功研发出纳米纤维宏量生产设备及核心工艺， ...
