He mea kaulana loa ʻo Graphene i kēia mau lā, a ua loaʻa iā ia ka nānā nui ʻana i nā transistors hopena, nā pā, nā capacitors, polymer nanosynthesis, a me ka wehe ʻana o ka membrane.Hiki ke lilo nā mea membrane hou i ka hanauna hou o nā huahana membrane mainstream.
Na waiwai o Graphene Oxide
ʻO Graphene oxide (GO) kahi kiʻiʻoniʻoni planar honeycomb ʻelua-dimensional i haku ʻia me kahi papa hoʻokahi o nā ʻātoma kalapona.ʻO ka hui kemika i haku ʻia me nā ʻātoma kalapona a me nā pūʻulu hana i loko o ka oxygen polar.ʻO GO ma muli o ke ʻano o nā pūʻulu hana i loko o ka oxygen.A ʻo ka puʻunaue ʻike ʻole e hoʻopaʻapaʻa ʻia kona ʻano molekala.Ma waena o lākou, ʻike nui ʻia ka ʻōnaehana Lerf-Klinowski, a ua manaʻo ʻia aia ʻekolu mau pūʻulu hana nui ma GO, ʻo ia hoʻi nā hui hydroxyl a me epoxy aia ma ka ʻili, a me nā mea ma ka lihi.carboxyl.
Loaʻa iā GO kahi hoʻolālā planar ʻelua ʻano like me ka graphene.ʻO ka ʻokoʻa, ʻo GO e hoʻolauna i kahi helu nui o nā pūʻulu hana i loko o ka oxygen polar ma ka ʻili o ka iwi kalapona ma muli o ka oxidation, e like me -O-, -COOH, -OH, etc. ka hoʻolālā GO.Hoʻopili ʻia nā papa GO e ka nui o nā paʻa hydrogen, a ua hoʻopili ʻia ka hoʻolālā planar ʻelua-dimensional e nā paʻa covalent ikaika, e lilo ai ia i hydrophilic loa.Ua manaʻo ʻia ʻo GO he mea hydrophilic, akā he amphiphilic maoli ʻo GO, e hōʻike ana i ka loli ʻana mai ka hydrophilic a i ka hydrophobic mai ka lihi a i ke kikowaena.Hāʻawi ke ʻano kūʻokoʻa o GO iā ia i kahi ʻāpana kikoʻī nui, thermodynamics kūʻokoʻa He koʻikoʻi noiʻi maikaʻi a me nā manaʻo noiʻi ma nā kula o ka biology, lāʻau lapaʻau, a me nā mea waiwai.
I kekahi mau lā i hala aku nei, ua paʻi ka puke pai honua "Nature" i ka ʻaha kūkā "Ion sieving by cations controlling the interlayer spacing of graphene oxide films".Manaʻo kēia noiʻi a ʻike i ka mana pololei o nā membrane graphene e nā ion hydrated, e hōʻike ana i ka sieving ion maikaʻi a me ka desalination wai kai.hoʻokō.
Wahi a ka ʻoihana, ua hoʻolohe koʻu ʻāina i ka noiʻi a me ka hoʻomohala ʻana ma ke kahua o ka graphene ma mua.Mai ka makahiki 2012, ua hoʻopuka koʻu ʻāina ma mua o 10 mau kulekele pili i ka graphene.I ka makahiki 2015, ua manaʻo ʻia ka palapala papahana papahana mua o ka pae aupuni "He mau manaʻo e pili ana i ka hoʻonui ʻana i ka hana hou a me ka hoʻomohala ʻana o ka ʻoihana Graphene" e kūkulu i ka ʻoihana graphene i kahi ʻoihana alakaʻi, a e hoʻokumu i kahi ʻōnaehana ʻoihana graphene piha ma 2020. e like me ka 13th Five-Year Plan i hoʻokomo i ka graphene i loko o ke kahua o nā mea hou i hoʻomohala ikaika ʻia.Manaʻo ka ʻoihana e ʻoi aku ka nui o ka mākeke graphene o koʻu ʻāina ma mua o 10 biliona yuan ma 2017. Ke wikiwiki nei ka hoʻomohala ʻana o ka ʻoihana graphene, a ʻo nā hui pili e manaʻo ʻia e pōmaikaʻi.
