Njengoba izakhiwo ezikhethekile zegrafu zaziwa, izindlela eziningi zokulungiselela ama-graphite ziye zakhiwa. I-Graphene ilungiselelwe ku-graphene oxide ngenqubo eyinkimbinkimbi yamakhemikhali, lapho kungezwa khona i-oxidizing kanye nokunciphisa ama-ejenti, futhi i-graphene anchents elungiselelwe ngaphansi kwalezi zimo zamakhemikhali ezinzima zivame ukuqukethe inani elikhulu lezinkinga.
I-Ultrasonic iyinye indlela efakazelwe engakhiqiza inani elikhulu eliphakeme - i-graphene yekhwalithi. I-Graphite ingezwa engxenyeni yama-dilite organic acid, ama-alcohols, namanzi, bese inxube isuselwa emisebeni ye-ultrasonic. I-acid isebenza njenge- "wedge ye-molecular" ehlukanisa amaphepha we-graphe. Ngale nqubo elula, inani elikhulu le-UNDSPERSERY, Phezulu - I-Grafshone yekhwalithi ehlakazekile emanzini akhiqizwa.
I-GROPHLE YIBALULEKILE - I-Carbon Nanomative ye-Carbon lapho ama-athomu e-carbon akha i-hexagonal honey honey condting nge-spr hybrid ama-arbid. I-Carbon's Carbon - I-Atom - Amashidi amnyama we-graphite yekhabhoni nge-non -
"Yinto encane kunazo zonke endaweni yonke futhi into enamandla kunazo zonke eyake yadalwa. Kubonisa ukuhamba okukhulu kwenkampani yenethiwekhi, kune-micrometer encane kunazo zonke (zero), futhi kungenza ama-micrometer amaningi - Spread ngaphandle kokusakazeka. I-Graphene ingakwazi ukuxhasa ama-desities amanje ama-oda ayisithupha wobukhulu obuphakeme kune-zethusi, imibukiso erekhoda ubulukhuni nobulukhuni, i-airtight, futhi ingavumelanisa izakhiwo ezingqubuzanayo njenge-brittleness ne-computicity. Ama-elekthronikhi ku-graphene The Transtory achazwa yi-Dirac Equation, evumela ukufundwa kwe-qunomena ehlobene ne-qunomena eBenchtop.
Isimiso sokuhlakazwa kwe-ultrasonic
Imishini yokuhlakazeka kwe-Ultrasonic isebenzisa i-ultrasonic cavitation ukusabalalisa izinhlayiya ezihlanganisiwe. Ibeka ukumiswa kwezinhlayiyana (isimo se-liquid) ukuthi iphathwe kwi-super - inkambu yomsindo oqinile futhi uyiphathe nge-amplitude efanele ye-ultrasonic. Ngaphansi komphumela we-cavitation, amazinga okushisa aphezulu, ukucindezela okuphezulu, ama-micro - jet, ukudlidliza okunamandla neminye imiphumela eyengeziwe kuzokuholela ekuqhekekeni kwamangqamuzana kanye nokwakhiwa kwesakhiwo esisodwa samangqamuzana. Lo mkhiqizo uphumelela ikakhulukazi ekusakazeni ama-nanomatadium (njenge-carbon nanotubes, i-graphene, i-silicon dioxide, njll.).
Inhloso yokuhlakazeka kwe-Graphene
Kunenombolo enkulu yezinto zokwenziwa kwe-graphite ngokwemvelo, futhi i-graphite ene-1 mm iqukethe izingqimba ezingaba yizigidi ezintathu ze-grapheene. Okukodwa - I-Layer Graphite ibizwa nge-graphene, engekho eFree State, kepha ikhona ngendlela yamaphepha e-graphite afakwe nge-multis graphene. Ngenxa yamandla abuthakathaka wokubamba amashidi we-graphite, izingqimba zingavulwa ngamandla angaphandle, ukuze zithole okukodwa - ukutholwa okukodwa -
