Nano -titanium dioxide decomposes bacteria e hoʻokō antibacterial hopena ma lalo o ka hana o photocatalytic. No ka mea, ʻo ke ʻano uila o nano -titanium dioxide he wahi kumukūʻai piha i ka TIO2 a me kahi ʻāpana alakaʻi ʻole. I loko o ka ʻōnaehana wai a me ka ea, aia ka nano -titanium dioxide ma lalo o ka lā, ʻoi loa ma lalo o nā kukuna ultraviolet. Ke piʻi a ʻoi paha ka ikehu uila i kona ʻāpana band Time. Hiki ke hoʻouluʻia nā mea uila mai ka'āpana kumukūʻai i ka'āpana alakaʻi. Hoʻopuka ʻia kahi ʻano hopena, kahi i hoʻopili ʻia a hoʻoheheʻe ʻia i loko o ka oxygen e hopu i nā electrons e lilo i O2 ·. Hoʻokumu ʻia nā radical manuahi supersonic anion i hana ʻia me ka hapa nui o nā mea kūlohelohe (oxidation). I ka manawa like, hiki ke hana ʻia ka CO2 a me H2O me nā mea kūlohelohe i loko o ka bacteria; ʻoiai e hoʻopili ʻia nā acupoints ma ka OH a me ka H2O oxidation o OH a me H2O ma ka ʻili o ka ʻili TIO2 i · OH, · OH, kahi e loaʻa ai ka mana oxidation ikaika. Hoʻopuka nā ʻātoma i nā radical manuahi hou, hoʻoulu i nā hopena kaulahao, a ma hope ke kumu o ka decomposition bacteria.

Aia ka hopena sterilization o TIO2 i kona hopena nui. ʻOiai he hopena photocatalytic ka titanium pink powder (TiO2 maʻamau), hiki iā ia ke hana i nā mea uila a me nā lua. He mea paʻakikī ke pāʻani i ka hopena o nā hopena antibacterial, a ua neʻe ʻo TiO2, i hiki i ka decentralization nano-level, mai ke kino a i ka ʻili. E like me ka lōʻihi o ka manawa o nā nanoseconds, picoseconds, a hiki i ka femllo, ua hoʻonui ʻia ka composite o nā uila uila a me nā lua i nā nanoseconds. Hiki iā ia ke neʻe koke i ka ʻili. Hoʻouka i nā meaola bacteria a pāʻani i kahi hopena antibacterial pili.

Hoʻohana nui ʻia ʻo TiO2 i nā textiles ma ke ʻano he ʻano hou o ka mea antibacterial inorganic
ʻO ka nano -level TIO2 particles he mau waiwai antibacterial ikaika ma lalo o ka mālamalama, a me ka piʻiʻana o ka hoʻonuiʻana o ka antibacterial a me ka manawa māmā, ua hoʻonuiʻia ka helu antibacterial, a ua hoʻoikaika nuiʻia ka hopena antibacterial. Hiki ke mālama i ka nano -TiO2 ma luna o ka lole me ke ʻano soking, a ʻo ka lole i hana ʻia he antibacteriality maopopo, akā pono e hoʻohui ʻia ka adhesive a me ka dispersant e hoʻomaikaʻi i ka hui ʻana o TIO2 a me ka lole. Ma hope o ka hoʻohui ʻana i nā mea hoʻopili a me nā mea hoʻopuehu, ʻoi aku ka maikaʻi o ka antibacteriality o ka lole.

ʻO nā mea maikaʻi o ka nano -titanium dioxide antibacterial: palekana a ʻaʻohe mea ʻawaʻawa no ke kino kanaka, ʻaʻohe huhū i ka ʻili; ikaika antibacterial hiki, ākea ākea o antibacterial laulā; aole pilau,; ka lōʻihi o ke kūpaʻa wai, ka wā mālama lōʻihi; maikaʻi ke kūpaʻa wela, ka hoʻololi ʻole ʻana i ke kala i ke kiʻekiʻe o ka wela, ʻaʻohe decomposition, me ka nānā ʻole i ka decomposition, me ka nānā ʻole i ka decomposition, me ka ʻole o ka decomposition. Mai volatilize, mai deteriorate; hikiwawe maikaʻi.
