I-Nano-titanium dioxide ibola ibhaktheriya ukuphumeza imiphumo ye-antibacterial phantsi kwesenzo se-photocatalytic. Ngenxa yokuba i-electronic structure ye-nano-titanium dioxide yindawo yexabiso egcwele i-TIO2 kunye nommandla ongenanto wesikhokelo. Kwinkqubo yamanzi kunye nomoya, i-nano-titanium dioxide iphantsi kwelanga, ngakumbi phantsi kwemitha ye-ultraviolet. Xa amandla e-elektroniki efikelela okanye edlula isithuba sebhendi yayo Ixesha. I-Electronics inokukhuthazwa ukusuka kwindawo yexabiso ukuya kwindawo yesikhokelo. Uthotho reactions kwenzeka, nto leyo adsorbed kwaye zinyibilike oksijini ukubamba electron ukwenza O2 ·. I-supersonic anion free radicals eyenziweyo yenziwa ngobuninzi bezinto eziphilayo (i-oxidation). Ngexesha elifanayo, i-CO2 kunye ne-H2O inokuveliswa ngezinto eziphilayo kwiibhaktheriya; ngelixa i-acupoints iya kuxutywa kwi-OH kunye ne-H2O ye-oxidation ye-OH kunye ne-H2O phezu kwendawo ye-TIO2 ukuya · OH, · OH, eya kuba nekhono elinamandla le-oxidation. Iiathom zivelisa iiradicals zasimahla, zivuselela ukusabela kwekhonkco, kwaye ekugqibeleni zibangele ukubola kwebhaktiriya.

Isiphumo sokuvala inzala ye-TIO2 ilele kwisiphumo sobungakanani bayo. Nangona i-titanium pink powder (i-TiO2 eqhelekileyo) nayo inefuthe le-photocatalytic, inokuvelisa i-electronics kunye nemingxuma. Kunzima ukudlala umphumo we-antibacterial effects, kwaye i-TiO2, efikelela kwinqanaba le-nano -level decentralization, iye yafuduswa ukusuka emzimbeni ukuya phezulu. Ngethuba nje ixesha le-nanoseconds, i-piccoseconds, kunye ne-femllo, i-composite ye-photochemical electronics kunye ne-cavities ikhuliswa kwii-nanoseconds. Iyakwazi ukuhamba ngokukhawuleza phezulu. Ukuhlaselwa kwezinto eziphilayo zebhaktheriya kwaye udlale umphumo ohambelana ne-antibacterial.

I-TiO2 isetyenziswa ngokubanzi kwiimpahla ezilukiweyo njengodidi olutsha lwe-agent ye-inorganic antibacterial
I-nano-level ye-TIO2 iinqununu zinezixhobo ezinamandla zokulwa ne-antibacterial phantsi kokukhanya, kwaye ngokunyuka kwe-concentration ye-antibacterial kunye nexesha lokukhanya, izinga lokulwa ne-antibacterial liyenyuka, kwaye umphumo we-antibacterial uqiniswa kakhulu. Kunokwenzeka ukunyanga i-nano -TiO2 kwilaphu kunye nendlela yokumanzisa, kwaye ilaphu elicutshungulweyo line-antibacterial ecacileyo, kodwa i-adhesive kunye ne-disperant kufuneka yongezwe ukuphucula ukudibanisa kwe-TIO2 kunye nelaphu. Emva kokufaka izinto zokuncamathelisa kunye ne-dispersing agents, i-antibacterial yelaphu inokusebenza kakuhle kokumelana namanzi.

Iingenelo ze-nano-titanium dioxide antibacterial: ikhuselekile kwaye ayinayo ityhefu kumzimba womntu, akukho ukucaphuka kwesikhumba; amandla okulwa ne-antibacterial, uluhlu olubanzi lwe-antibacterial range; akukho vumba,; ukumelana kwamanzi ixesha elide, ixesha elide lokugcina; ukuzinza okuhle kwe-thermal, umbala ongatshintshiyo kwiqondo lokushisa eliphezulu, akukho ukubola, kungakhathaliseki ukubola, kungakhathaliseki ukubola, kungakhathaliseki ukubola, kungakhathaliseki ukubola. Musa ukuguquguquka, musa ukuwohloka; ukungazinzi kakuhle.
