Evaluation of the possibility of using copolymer electrospun membranes in smart reactive fabrics

Albarrie已经开发了智能反应性织物，用作安装大功率变压器的土工织物。**这些智能反应性织物可在意外泄漏的情况下提供防油功能。Albarrie开发的智能反应织物**由三层组成：通过针刺将吸油嵌段共聚物插入两层聚丙烯**之间。当与油接触时，吸水嵌段共聚物凝胶化并**密封智能反应织物，以防止任何土壤被油污染。最近，以天然酯类为基础的新型变压器绝缘油已推向市场。不幸的是，**Albarrie开发的智能反应织物在容纳这些类型的油方面速度太慢。**人们可能会认为，如果共聚物的表面积增加，**聚合物遏制油的时间可能会减少。增加共聚物表面积的一种可能性是以**纳米纤维的形式使用它们，这种形式可以通过静电纺丝获得。**因此，本项目旨在研究利用纳米纤维膜提高阿尔巴里超级**吸水性聚合物反应速度的可能性，用于大功率变压器二次油封，重点是**天然酯基油。

Albarrie has developed smart reactive fabrics used, as geo textiles where high-power transformers are installed.**These smart reactive fabrics provide oil containment in case of accidental leaks. The smart reactive fabrics**developed by Albarrie consists of three layers: an oil absorbent block copolymer is inserted via needle punch**between two layers of polypropylene. When in contact with oil, the absorbent block copolymer gellifies and**seals the smart reactive fabric preventing any soil contamination by the oil. Recently, new natural ester-based**transformer-insulating-oils have been introduced to the market. The smart reactive fabrics developed by**Albarrie are unfortunately too slow for containment of these types of oil.**One could think that if the surface area of the copolymers is increased, the time for oil containment by the**polymer could decrease. One possibility to increase the surface area of the copolymers is to use them in the**form of nanofibers that can be obtained by electrospinning.**This project aims therefore at studying the possibility of improving the reaction rate of Albarrie super**absorbent polymer for high power transformer secondary oil containment application, with an emphasis on**natural ester-based oil, using membranes of nanofibers.
