Zusammenfassung:	Un proceso para sintetizar óxido de grafeno reducido a partir de laca en forma de grano sobre un sustrato, que comprende: preparar la disolución de laca en forma de grano en un alcohol C2-C4; sumergir el sustrato en la disolución de laca en forma de grano una o más veces; y calentar el sustrato en el intervalo de temperaturas de 400 ºC a 1200 ºC en atmósfera controlada de Ar/N2/Ar- H2/N2-H2 a un caudal de 100 a 500 seem durante un período de 10 a 120 minutos. The present invention relates to synthesizing reduced graphene oxide on the surface of a metal sheet and glass. The invention particularly relates to a process for coating a substrate with reduced graphene oxide using seedlac as a carbon source. As per the process of the current invention, a solution of seedlac is prepared in an alcohol and the substrate is dipped in to the solution for one or more time. The substrate is then dried in air for 1-10 minutes and thereafter, heated to a temperature range of 400 to 1200° C. under controlled atmosphere of Ar/N2/Ar-H2/N2-H2 at a different flow rate ranging from 100 to 500 seem for a period of 10 to 120 minutes.
