Hoʻonui ʻo Graphene i nā waiwai o nā plastics me ka hoʻemi ʻana i ka hoʻohana ʻana i nā mea maka ma ka 30 pakeneka.

Ua hoʻolaha ʻo Gerdau Graphene, kahi hui nanotechnology e hoʻolako ana i nā mea i hoʻonui ʻia me ka graphene no nā noi ʻoihana, ua hana ʻo ia i nā plastics i hoʻonui ʻia me ka graphene no ka polymer ma kahi Center for Advanced Materials ma São Paulo, Brazil i kākoʻo ʻia e ke aupuni Brazil. Ua hana ʻia ka hoʻolālā masterbatch resin polymeric hou i hoʻonui ʻia me ka graphene no ka propylene (PP) a me ka polyethylene (PE) ma ka laulima ʻana me ka mahele EMBRAPI SENAI/SP Advanced Materials o Brazil, a ke hana nei i kēia manawa i kahi moʻo o nā hoʻokolohua noi ʻoihana ma ka hale hana ʻo Gerdau Graphene. ʻOi aku ka ikaika o nā huahana thermoplastic hou i hana ʻia me ka hoʻohana ʻana i kēia mau ʻano hana a hāʻawi i ka hana holoʻokoʻa maikaʻi aʻe ʻoiai ʻoi aku ka liʻiliʻi o ka hana ʻana a me ka hoʻoulu ʻana i ka liʻiliʻi o ka ʻōpala ma ke kaulahao waiwai.
ʻO Graphene, i manaʻo ʻia ʻo ia ka mea ikaika loa ma ka honua, he ʻāpana mānoanoa o ke kalapona 1 a 10 mau ʻātoma ka mānoanoa hiki ke hoʻololi ʻia no nā ʻano hoʻohana like ʻole a hoʻohui ʻia i nā mea ʻoihana. Mai kona ʻike ʻia ʻana i ka makahiki 2004, ua huki ka honua holoʻokoʻa i nā waiwai kemika, kino, uila, wela a me nā waiwai mechanical kupaianaha o graphene, a ua hāʻawi ʻia ka mea nāna i ʻike i ka Nobel Prize in Chemistry. Hiki ke hui pū ʻia ʻo Graphene me nā plastics, e hāʻawi ana i ka ikaika kupaianaha o ka plastic masterbatch, e hoʻoikaika ana i ka plastic i hui pū ʻia. Ma waho aʻe o ka hoʻomaikaʻi ʻana i nā waiwai kino a me nā mechanical, hoʻonui ka graphene i nā waiwai pale i nā wai a me nā kinoea, pale i ka wā ʻino, ka oxidation, a me nā kukuna UV, a hoʻomaikaʻi i ka conductivity uila a me ka wela.
