Graphene imawonjezera zinthu zamapulasitiki ndikuchepetsa kugwiritsa ntchito zinthu zopangira ndi 30 peresenti.

Gerdau Graphene, kampani ya nanotechnology yomwe imapereka zida zapamwamba za graphene zopangira mafakitale, idalengeza kuti yapanga mapulasitiki owonjezera a graphene a polima ku Center for Advanced Materials yothandizidwa ndi boma ku Brazil ku São Paulo, Brazil.Mapangidwe atsopano a graphene-enhanced polymeric resin masterbatch a propylene (PP) ndi polyethylene (PE) adapangidwa mogwirizana ndi gawo la Brazil EMBRAPI SENAI / SP Advanced Materials division, ndipo pakali pano akukumana ndi mayesero angapo ogwiritsira ntchito mafakitale ku Gerdau Graphene.Zopangira zatsopano za thermoplastic zomwe zimapangidwa pogwiritsa ntchito mawonekedwewa zimakhala zamphamvu komanso zimapereka magwiridwe antchito abwinoko pomwe zimakhala zotsika mtengo kupanga ndikutulutsa zinyalala zocheperako mu unyolo wamtengo wapatali.
Graphene, yomwe imatengedwa kuti ndi chinthu champhamvu kwambiri padziko lapansi, ndi pepala lowundana la maatomu a 1 mpaka 10 omwe amatha kusinthidwa kuti agwiritse ntchito mosiyanasiyana ndikuwonjezedwa kuzinthu zamakampani.Chiyambireni kupezeka kwake mu 2004, luso la graphene lodabwitsa la mankhwala, thupi, magetsi, kutentha ndi makina akopa chidwi padziko lonse lapansi, ndipo wotulukirayo wapatsidwa Mphotho ya Nobel mu Chemistry.Graphene imatha kusakanikirana ndi mapulasitiki, kupatsa pulasitiki masterbatch mphamvu zosaneneka, ndikupangitsa pulasitiki yophatikizika kukhala yamphamvu kwambiri.Kuphatikiza pa kuwongolera zinthu zakuthupi ndi zamakina, graphene imakulitsa zotchinga zamadzimadzi ndi mpweya, imateteza ku nyengo, makutidwe ndi okosijeni, ndi kuwala kwa UV, komanso imapangitsa kuti magetsi ndi matenthedwe aziyenda bwino.
