Abstract

Procedimiento para la obtención de suspensiones o muestras sólidas de grafeno dopado o no con heteroátomos a partir de polímeros naturales o sintéticos, los cuales se someten a una etapa de pirólisis en horno en ausencia de oxígeno a temperaturas entre 400 y 1200ºC y a una posterior exfoliación en una fase líquida. Los polímeros utilizados preferiblemente son polisacáridos como el quitosán, alignato y ácido alígnico, pudiendo éstos estar dopados con algún heteroátomo. La presente invención tiene su principal aplicación en microelectrónica y dispositivos fotovoltaicos donde las láminas de grafeno son de gran utilidad; además, el grafeno preparado puede servir como aditivo de polímeros y materiales cerámicos.
