I kēia manawa, ʻo ka hana ʻana a me ka hoʻohana ʻana i nā nanomaterials ua huki ʻia ka manaʻo mai nā ʻāina like ʻole.Ke hoʻomau nei ka holomua o ka nanotechnology o Kina, a ua hoʻokō maikaʻi ʻia ka hana ʻenehana a i ʻole ka hoʻāʻo ʻana i ka nanoscale SiO2, TiO2, Al2O3, ZnO2, Fe2O3 a me nā mea pauka ʻē aʻe.Eia nō naʻe, ʻo ke kaʻina hana o kēia manawa a me nā kumukūʻai kiʻekiʻe o kona nāwaliwali make, e hoʻopilikia i ka hoʻohana ākea o nā nanomaterials.No laila, pono ka hoʻomaikaʻi mau ʻana.
Ma muli o ka hoʻolālā uila kūikawā a me ka radius atomika nui o nā mea honua laha, ʻokoʻa loa ko lākou mau mea kemika mai nā mea ʻē aʻe.No laila, ʻokoʻa ke ʻano o ka hoʻomākaukau ʻana a me ka ʻenehana ma hope o ka mālama ʻana o ka honua nano oxides mai nā mea ʻē aʻe.ʻO nā ʻano noiʻi nui he:
1. Keʻano o ka ua: me ka ua oxalic acid, ka ua carbonate, ka ua hydroxide, ka ua homogeneous, ka ua paʻakikī, a me nā mea'ē aʻe. nā huahana maʻemaʻe kiʻekiʻe.Akā paʻakikī ke kānana a maʻalahi hoʻi e hōʻuluʻulu.
2. Hydrothermal ala: E hoʻokē a hoʻoikaika i ka hydrolysis pane o nā ion ma lalo o ke kiʻekiʻe wela a me ka puʻe kūlana, a me ka dispersed nanocrystalline nuclei.Hiki i kēia ʻano ke loaʻa nā pauka nanometer me ka hoʻopuehu like ʻana a me ka hāʻawi ʻana i ka nui o nā ʻāpana liʻiliʻi, akā pono ia i ka wela kiʻekiʻe a me nā mea hana kiʻekiʻe, he pipiʻi a palekana ke hana.
3. gel ala: He hana koʻikoʻi ia no ka hoʻomākaukau ʻana i nā mea inorganic, a he hana koʻikoʻi i ka synthesis inorganic.Ma ka wela haʻahaʻa, hiki i nā pūhui organometallic a i ʻole nā mea paʻakikī ke hana i ka sol ma o ka polymerization a i ʻole hydrolysis, a hana i ka gel ma lalo o kekahi mau kūlana.Hiki i ka hoʻomaʻamaʻa wela hou ke hana i nā noodle Rice ultrafine me ka ʻili kikoʻī nui aʻe a ʻoi aku ka maikaʻi o ka hoʻopuehu ʻana.Hiki ke hoʻokō ʻia kēia ʻano hana ma lalo o nā kūlana haʻahaʻa, e hopena i ka pauka me kahi ʻāpana ākea a ʻoi aku ka maikaʻi o ka dispersibility.Eia naʻe, lōʻihi ka manawa pane a he mau lā e hoʻopau ai, e paʻakikī ai ka hoʻokō ʻana i nā koi o ka ʻoihana.
4. ʻO ke ʻano o ka pae paʻa: lawe ʻia ka decomposition wela kiʻekiʻe ma o nā pūhui paʻa a i ʻole nā hopena paʻa waena.No ka laʻana, hui pū ʻia ka nitrate honua laha a me ka waikawa oxalic e ka wili pōleʻa paʻa paʻa e hana i waena o ka oxalate honua laha ʻole, a laila decomposed i ka wela kiʻekiʻe e loaʻa ai ka pauka ultrafine.He kiʻekiʻe ka hopena o kēia ʻano, nā mea hana maʻalahi, a me ka hana maʻalahi, akā ʻo ka hopena o ka pauka he morphology irregular a me ke ʻano like ʻole.
ʻAʻole kūʻokoʻa kēia mau ʻano a ʻaʻole hiki ke pili pono i ka ʻoihana.Nui nō hoʻi nā ʻano hoʻomākaukau, e like me ke ʻano microemulsion organik, alcoholysis, etc.
No ka ʻike hou aku e ʻoluʻolu e kelepona mai iā mākou
