项目摘要

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.

Albarrie开发了智能反应织物，用作安装高功率变压器的土工织物。**这些智能活性织物在意外泄漏的情况下提供油密封。由Albarrie开发的智能活性织物 ** 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，吸收性嵌段共聚物胶凝并密封智能活性织物，防止油污染任何污垢。最近，新的天然酯基变压器绝缘油已被引入市场。不幸的是，**Albarrie开发的智能活性织物对这些类型的油的容纳速度太慢。人们可能会认为，如果共聚物的表面积增加，** 聚合物控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，所述纳米纤维可以通过静电纺丝获得。因此，本项目旨在研究使用纳米纤维膜提高Albarrie超 ** 吸收性聚合物用于高功率Transformer二次油密封应用的反应速率的可能性，重点是 ** 天然酯基油。
