Graphene ua rau cov khoom ntawm cov yas zoo dua thaum txo cov khoom siv raw los ntawm 30 feem pua.
Gerdau Graphene, ib lub tuam txhab nanotechnology uas muab cov khoom siv graphene-enhanced rau kev siv hauv kev lag luam, tshaj tawm tias nws tau tsim cov yas graphene-enhanced rau polymer ntawm Brazilian tsoomfwv nyiaj txiag Center for Advanced Materials hauv São Paulo, Brazil. Cov qauv tshiab graphene-enhanced polymeric resin masterbatch rau propylene (PP) thiab polyethylene (PE) tau tsim los ntawm kev koom tes nrog Brazilian EMBRAPI SENAI/SP Advanced Materials division, thiab tam sim no tab tom sim ntau yam kev siv hauv kev lag luam ntawm Gerdau Graphene qhov chaw. Cov khoom thermoplastic tshiab tsim los ntawm kev siv cov qauv no yuav muaj zog dua thiab muaj kev ua tau zoo dua thaum pheej yig dua los tsim thiab tsim cov khib nyiab tsawg dua thoob plaws hauv cov saw hlau muaj nqis.
Graphene, suav hais tias yog cov khoom muaj zog tshaj plaws hauv ntiaj teb, yog ib daim ntawv tuab ntawm cov pa roj carbon 1 txog 10 atoms tuab uas tuaj yeem hloov kho rau ntau yam kev siv thiab ntxiv rau cov khoom siv hauv kev lag luam. Txij li thaum nws tau tshawb pom hauv xyoo 2004, graphene cov khoom siv tshuaj lom neeg, lub cev, hluav taws xob, thermal thiab mechanical zoo kawg nkaus tau nyiam thoob ntiaj teb, thiab nws tus neeg tshawb pom tau txais txiaj ntsig Nobel hauv Chemistry. Graphene tuaj yeem sib xyaw nrog cov yas, ua rau cov yas masterbatch muaj zog heev, ua rau cov yas sib xyaw ua ke muaj zog dua. Ntxiv nrog rau kev txhim kho cov khoom siv lub cev thiab cov khoom siv kho tshuab, graphene txhim kho cov khoom tiv thaiv rau cov kua thiab cov pa roj, tiv thaiv kev puas tsuaj, oxidation, thiab UV rays, thiab txhim kho kev coj hluav taws xob thiab thermal.
