Graphene waa kiristaalo laba-cabbir ah oo laga sameeyay atamka kaarboon hal atamka oo keliya oo qaro weyn, lagana siibay walxo garaafeed flake ah. Graphene waxa ay leedahay codsiyo kala duwan oo kala duwan taas oo ay ugu wacan tahay sifooyinkiisa ugu wanagsan ee indhaha, korontada iyo makaanikada. Haddaba ma jiraa xidhiidh ka dhexeeya graphite flake iyo graphene? Taxanahan yar ee soo socda ee Falanqaynta xidhiidhka ka dhexeeya graphite flake iyo graphene:
Garaafka caleen
1. Habka soo saarista ee wax soo saarka tirada badan ee graphene inta badan lagama helo graphite flake, laakiin laga helo gaasaska kaarboon ku jira sida methane iyo acetylene. Inkasta oo magaca, wax-soo-saarka graphene uusan asal ahaan ka iman garaafyada flake. Waxa laga sameeyaa gaasaska kaarboonku ku jiro sida methane iyo acetylene, xataa hadda waxa jira habab lagaga soo saari karo graphene dhirta beeraysa, hadda waxa jira habab graphene looga soo saaro geedaha shaaha.
2. Garaafka Flake waxa ku jira malaayiin graphene. Graphene dhab ahaantii jira dabeecadda, haddii xiriirka ka dhexeeya graphene iyo graphite flake, ka dibna graphene lakabka by lakabka waa graphite flake, graphene waa qaab-dhismeedka monolayer aad u yar. Hal millimitir oo graphite flake ah ayaa la sheegay in uu ka kooban yahay ilaa saddex milyan oo lakab oo graphene ah, waxaana la arki karaa ganaaxa graphene, si loo isticmaalo tusaale garaaf ah, marka aan ku qorno erayada warqad qalin, waxaa jira dhowr ama tobanaan kun oo lakab. ee graphene.
Habka diyaarinta ee graphene ka graphite flake waa mid fudud, oo leh cillado yar iyo oksijiinta content, dhalidda sare ee graphene, size dhexdhexaad ah, iyo qiimo jaban, kaas oo ku habboon wax soo saarka warshadaha ballaaran.
