Abstract—

The current state of the art in the field of highly heat-resistant optical fiber coatings based on polyimides and polyamides is reviewed. Various methods of coating formation, including those from poly(amic acid) precursors, organosoluble polyimides, and aliphatic and aromatic polyamides, are considered, and their properties and applications are described. It is demonstrated that organosoluble polyimides and polyamides show promise as protective coatings of optical fibers that withstand prolonged exposure to moisture and high temperatures (350°C up to 24 h) without the loss of strength by the optical fibers.

光纤的高耐热性聚合物涂层

摘要-

综述了基于聚酰亚胺和聚酰胺的高耐热性光纤涂层领域的最新技术。考虑了各种涂层形成方法，包括由聚（酰胺酸）前体，有机可溶性聚酰亚胺以及脂族和芳族聚酰胺形成的方法，并描述了它们的性质和应用。已经证明有机可溶性聚酰亚胺和聚酰胺作为光纤的保护性涂层显示出了希望，该涂层能够经受长时间暴露于湿气和高温（350°C长达24小时）而不会损失光纤的强度。
