I-Graphene Khulisa izakhiwo zamapulasitiki ngenkathi kunciphisa ukusetshenziswa kwezinto ezibonakalayo eziluhlaza ngamaphesenti angama-30.

I-Gerdau Ghoprage, inkampani ye-nanotechnology enikezela ngezinto ezithuthukisiwe ze-grapheneenance ezithuthukisiwe zezicelo zezimboni, imemezele ukuthi idale amapulasitiki athuthukile athuthukisiwe we-polymer esikhungweni esixhaswe nguhulumeni waseBrazil eSão Paulo, eBrazil. I-polymeric resin masterbatch ye-polymeric eyenziwe nge-propylene (PP) ne-polyethylene (pe) yadalwa ngokubambisana ne-Embrapiya Material Devation Division, futhi okwamanje itholakala ochungechungeni lwezinto ezisetshenziswayo zezimboni eGerdau GraphInelity. Imikhiqizo emisha ye-thermoplastic ekhiqizwa esebenzisa lezi zinqubo izoba namandla futhi inikeze okungcono kokusebenza okungcono ngenkathi kushibhile ukukhiqiza nokwenza imfucuza emncane kakhulu kulo lonke i-chain yenani.
I-Graphene, kubhekwe njengento enamandla kunazo zonke emhlabeni, ishidi eliminyene le-carbon 1 kuya ku-10 ama-athomu aminyene angaguqulwa ngokusetshenziswa okuhlukahlukene futhi angezwe ezintweni zezimboni. Kusukela ekutholweni kwayo ngo-2004, amakhemikhali angajwayelekile, angokomzimba, kagesi, ashisayo nezemishini adonsele ukunakwa komhlaba wonke, futhi ukutholakala kwalo kunikezwe umklomelo kaNobel eChemistry. I-graphete ingahlanganiswa namapulasitiki, inikeze amandla ama-masterbatch amangalisayo, okwenza ipulasitiki ehlanganisiwe ibe namandla ngokwengeziwe. Ngaphezu kokwenza ngcono izakhiwo zomzimba nezemishini, i-graphene ithuthukisa izithiyo zokuvimba ezitsheni namagesi, ivikela ngokumelene nesimo sezulu, i-oxidation, kanye ne-UV ray, futhi ithuthukise ukusebenza kukagesi nokushisayo.
