Abstract

Un matériau conducteur en fibre aramide selon la présente invention est obtenu en faisant adhérer une feuille de graphène à une surface d'un matériau en fibre aramide au moyen d'un adhésif biologique. Selon un mode de réalisation de la présente invention, la surface du matériau en fibre aramide est revêtue d'une solution adhésive contenant un bio-adhésif, une feuille de graphène et un solvant. La présente invention n'entraîne pas de court-circuit provoqué par la flexion d'un matériau en fibre aramide grâce à la flexibilité de la feuille de graphène adhérant au matériau en fibre aramide, ce qui permet de conserver des propriétés mécaniques telles que sa résistance, tout en améliorant considérablement sa conductivité électrique. De plus, en raison de l'excellente adhérence amphotère d'un adhésif biologique, la feuille de graphène présentant une flexibilité est solidement collée à la surface du matériau en fibre aramide, ce qui permet d'empêcher plus efficacement un court-circuit dû à la flexion du matériau en fibre aramide.
