Low dimensional carbon allotropes are commonly used in composites, and when combined with magnetic nanostructures, they create versatile materials for sensitive electrodes. Magnetic composites based on permalloy nanowires with graphene oxide and reduced graphene oxide show improved conductivity compared to the pristine matrix, with a more pronounced effect observed in the graphene oxide-based composite, making it an attractive alternative for sensing purposes.
Low dimensional carbon allotropes are the most used materials in composites. In addition, when magnetic nanostructures are assembled with carbon-based materials, a versatile material for building sensitive electrodes is achieved. Here, we propose a route to obtain magnetic composites based on both graphene oxide and reduced graphene oxide with permalloy nanowires. A comparative analysis of the electrochemical performance for such composites reveals that a relatively small amount of magnetic nanowires leads to an increased conductivity with respect to that of the pristine matrix, being such effect more pronounced for the graphene oxide-based composite. Therefore, the presence of permalloy nanostructures plays a determinant role in the conductive properties of graphene oxide-based materials, providing an attractive alternative for sensing purposes.
