El graf\u00e8 \u00e9s un al\u2219l\u00f2trop del carboni, el grafit s\u00f3n varies capes de carboni enlla\u00e7ades entre si, i el graf\u00e8 es una sola capa d\u2019\u00e0toms. Els enlla\u00e7os del carboni son covalents, son forts, i de forma hexagonal.
Hi ha dues maneres d\u2019obtenir el graf\u00e8. El material utilitzat en qualsevol dels dos tipus d\u2019exfoliaci\u00f3, es el grafit pirol\u00edtic, aquest grafit es diferencia principalment per les propietats magn\u00e8tiques, ja que es diamagn\u00e8tic, el diamagnetisme, \u00e9s una forma molt d\u00e8bil de magnetisme apareguda quan hi ha un camp magn\u00e8tic extern .
L\u2019exfoliaci\u00f3 mec\u00e0nica: amb una cinta adhesiva, grafit en pols, es pot obtenir mostres petites i d\u2019alta qualitat de graf\u00e8.
L\u2019exfoliaci\u00f3 qu\u00edmica, consisteix en exfoliar el grafit per sonicaci\u00f3, es a dir, per ultrasons. S\u2019utilitza \u00f2xid de grafit aqu\u00f3s per aquesta exfoliaci\u00f3, despr\u00e9s queda \u00f2xid de graf\u00e8, i aleshores cal reduir-lo per obtenir graf\u00e8 i en fer-ho perd qualitats o be i resten impureses. Tot i aix\u00ed, l\u2019\u00f2xid de graf\u00e8 tamb\u00e9 s\u2019utilitza.
El CVD es una c\u00e0mera de gas, dins hi ha un substrat, que es metal\u2219lic i catal\u00edtic, s\u2019introdueix el gas, CH4 (met\u00e0), que en passar per la finestra de quars, es separa l\u2019H del C, que s\u2019adherir\u00e0 al substrat en forma de
graf\u00e8. Com que el CVD es molt car, es va desenvolupar aquest m\u00e8tode, que te el mateix funcionament amb la diferencia de que es un proc\u00e9s continuat, que permet mes joc en les dimensions de la mostra, una l\u00e0mina de Cu, va rodant i s\u2019hi va adherint el graf\u00e8. Despr\u00e9s el Cu es dissol, deixant la l\u00e0mina de graf\u00e8.
Experiment de la batedora, \u00e9s una exfoliaci\u00f3 qu\u00edmica molt rudiment\u00e0ria, es necessita grafit, aigua, detergent i una batedora, el detergent ajuda a fer d\u2019exfoliant a les fulles de la batedora.<\/p>\n
