Método de funcionalización química para la obtención de óxido de grafeno adherido a la superficie de placas de grafito pirolítica de alta densidad por spray coating ácido

Abstract: En los últimos años el óxido de grafeno ha sido motivo de estudio debido a sus propiedades electrónicas, magnéticas, térmicas y mecánicas. Este estudio presenta dos métodos diferentes de funcionalización química para la obtención óxidos de grafeno (GO) adheridos a una superficie de grafito pirolítico de alta densidad (HOPG) por spray coating ácido. Para el rociado en el primer método, se utilizaron dos ácidos fuertes (H2SO4 y HNO3). En el segundo método de rociado, se utilizaron tres ácidos fuertes (H2SO4/HNO3… Show more

“…The experiment shows that the PEG modified GO nanoparticles fill the micro‐pits on the surface of the disc, which not only blocks the direct contact between friction pairs, but also prevents the formation of copper transfer film, thus reducing the debris and reducing the wear rate. In addition, the layered structure of PEG modified GO nanoparticles makes it easy to implement 39,40 …”
