The complete removal of remaining polymer debris after stripping of optical fiber cables is essential for high precision connection between two fibers. It can be anticipated that electrospun porous membranes as cleaning wipes are able to trap and retain polymer debris within their pores. Impregnation of an oil-in-water emulsion as cleaning agent lowers the interfacial tension between debris and the optical fiber thereby enabling the straightforward removal of polymer debris from the optical fiber.
Electrospun membranes of poly(ethylene terephthalate) (PET) and cellulose acetate (CA) were obtained with fiber diameters of 0.430 μm and 2 μm respectively. The oil-in-water emulsion was formulated with 10 wt% medium chain triglyceride (MCT) and 10 wt% Tween 80 surfactant in an aqueous phosphate buffer solution.
In a scoring range from 0 to 5 for which the score 0 indicated superior cleaning and the score 5 referred to the least efficient cleaning, the electrospun fiber mats (without emulsion) scored within the range of 2-4 while emulsion impregnated electrospun fiber mats revealed the best score of 0. A drastic improvement was thus clearly evident from the obtained results when the cleaning emulsion was applied. The materials developed herein thus represent a new class of soft cleaning agents for optical fibers.
在剥离光缆后彻底清除残留的聚合物碎片对于两根光纤之间的高精度连接至关重要。可以预期，作为清洁擦拭布的静电纺多孔膜能够捕获并保留其孔内的聚合物碎片。将油包水乳状液作为清洁剂浸渍可以降低碎片与光纤之间的界面张力，从而能够从光纤上直接清除聚合物碎片。
获得了纤维直径分别为 0.430 μm 和 2 μm 的聚对苯二甲酸乙二醇酯（PET）和醋酸纤维素（CA）的静电纺膜。油包水乳状液由 10 wt% 中链甘油三酯（MCT）和 10 wt% 吐温 80 表面活性剂在磷酸缓冲盐水溶液中配制而成。
评分范围为 0 到 5，其中 0 表示出色的清洁度，5 表示清洁效果最差，无纺静电纺纤维垫的评分为 2-4，而浸渍有乳液的无纺静电纺纤维垫的评分为 0。因此，当使用清洁乳液时，结果明显得到了极大的改善。因此，本文开发的材料代表了用于光纤的一类新型软清洁剂。
