Abstract
(EN) A graphene-sensitized optical fiber lactic acid sensor and a preparation method therefor. The graphene-sensitized optical fiber lactic acid sensor comprises: an optical fiber and a nickel plating layer. The preparation method comprises growing a graphene layer at a polished area after the optical fiber is fused and tapered, and coating the graphene layer with the nickel plating layer. A single mode optical fiber is tapered, graphene is directly grown at an optical fiber polished area by using a chemical deposition method to form a complete uniform graphene layer, so that a nickel sensitive material is stably combined with the optical fiber, thereby manufacturing a novel graphene-based optical fiber lactic acid sensor, and achieving good linearity fitting degree and repeatability in lactic acid measurement at a low concentration.
(FR) Capteur d'acide lactique à fibre optique à base de graphène et son procédé de préparation. Le capteur d'acide lactique à fibre optique à base de graphène comprend : une fibre optique et une couche de placage de nickel. Le procédé de préparation comprend la croissance d'une couche de graphène au niveau d'une zone polie après que la fibre optique soit fondue et effilée, et le revêtement de la couche de graphène à l'aide de la couche de placage de nickel. Une fibre optique monomode est effilée, le graphène est directement mis en croissance au niveau d'une zone polie de fibre optique à l'aide d'un procédé de dépôt chimique afin de former une couche de graphène uniforme complète, de telle sorte qu'un matériau sensible au nickel est associé de façon stable à la fibre optique, ce qui permet de fabriquer un nouveau capteur d'acide lactique à fibre optique à base de graphène, et d'obtenir un bon degré d'ajustement de linéarité et une bonne répétabilité de la mesure d'acide lactique à une faible concentration.
