Abstract

The design of new electronic devices has been a tireless research process so far in the twenty-first century. The development of conductive inks has become one of the most viable alternatives in these designs, so new formulations have been presented in the scientific world for several years. One of the main constituents that has been used most in the formulation of these conductive inks has been graphene oxide (OG). This, due to the exceptional properties that this nanomaterial presents. Moreover, if graphene oxide is modified with metal nanoparticles (NPM), its conductive properties are greatly increased. The implementation of conductive inks based on graphene oxide with metal nanoparticles (OG/NPM) has become a subject of scientific study today and the development of these water-based inks allows to reduce costs in their production. In this sense, the main objective of the project is the development of a conductive ink formulated based on graphene oxide (OG) modified with metal nanoparticles (NPM) (mainly Ag, Au, Cu, Ni, Zn or Nb), in such a way as to modify the conductive properties of graphene oxide and that it has the appropriate characteristics to be adhered on different fibers (natural and / or synthetic). This, in order to achieve a suitable material for the design of flexible electronic systems.
