Nano-titanium dioxide decomposes cov kab mob kom ua tiav cov tshuaj tua kab mob hauv qab kev ua ntawm photocatalytic. Vim tias cov qauv hluav taws xob ntawm nano-titanium dioxide yog thaj tsam nqi tag nrho ntawm TIO2 thiab ib qho chaw qhia khoob. Hauv dej thiab huab cua, nano-titanium dioxide nyob rau hauv lub hnub, tshwj xeeb tshaj yog nyob rau hauv ultraviolet rays. Thaum lub zog hluav taws xob ncav cuag lossis tshaj nws qhov sib txawv ntawm lub sijhawm. Cov khoom siv hluav taws xob tuaj yeem txhawb nqa los ntawm thaj chaw nqe mus rau thaj chaw qhia. Ib qho kev tshwm sim tshwm sim, uas yog adsorbed thiab yaj hauv oxygen kom ntes electrons los ua O2 ·. Lub generated supersonic anion dawb radicals yog generated nrog feem ntau cov organic teeb meem tshwm sim (oxidation). Tib lub sijhawm, CO2 thiab H2O tuaj yeem tsim nrog cov khoom organic hauv cov kab mob; thaum lub acupoints yuav absorbed ntawm OH thiab H2O oxidation ntawm OH thiab H2O nyob rau saum npoo ntawm TIO2 nto rau · OH, · OH, uas yuav muaj zog oxidation muaj peev xwm. Atoms tsim cov dawb radicals tshiab, txhawb kev sib txuas lus, thiab thaum kawg ua rau cov kab mob decomposition.

Cov nyhuv sterilization ntawm TIO2 nyob rau hauv nws cov nyhuv quantum loj. Txawm hais tias titanium liab hmoov (ib txwm TiO2) kuj muaj cov nyhuv photocatalytic, nws tuaj yeem tsim hluav taws xob thiab qhov. Nws yog ib qho nyuaj rau kev ua si ntawm cov tshuaj tua kab mob, thiab TiO2, uas nce mus txog qib ntawm nano-level decentralization, tau tsiv tawm ntawm lub cev mus rau saum npoo. Ntev npaum li lub sijhawm ntawm nanoseconds, picoseconds, thiab txawm tias femlo, qhov sib xyaw ntawm photochemical electronics thiab kab noj hniav yog magnified nyob rau hauv nanoseconds. Nws tuaj yeem txav mus sai sai rau saum npoo. Tawm tsam cov kab mob kab mob thiab ua kom muaj cov kab mob sib kis.

TiO2 yog siv dav hauv textiles raws li hom tshiab ntawm inorganic antibacterial agent
Cov nano-level TIO2 cov khoom muaj cov tshuaj tua kab mob muaj zog nyob rau hauv lub teeb, thiab nrog kev nce ntawm cov kab mob antibacterial concentration thiab lub teeb lub sij hawm, tus nqi tshuaj tua kab mob yog nce, thiab cov nyhuv antibacterial muaj zog ntxiv. Nws yog qhov ua tau los kho cov nano-TiO2 ntawm cov ntaub nrog txoj kev ntub dej, thiab cov ntaub ua tiav muaj cov kab mob ua kom pom tseeb, tab sis cov nplaum thiab dispersant yuav tsum tau ntxiv los txhim kho kev sib xyaw ntawm TIO2 thiab ntaub. Tom qab ntxiv cov nplaum thiab cov tshuaj tua kab mob, cov tshuaj tua kab mob ntawm cov ntaub muaj dej-resistant kev ua tau zoo.

Qhov zoo ntawm nano-titanium dioxide antibacterial: muaj kev nyab xeeb thiab tsis muaj tshuaj lom rau tib neeg lub cev, tsis muaj qhov khaus ntawm daim tawv nqaij; muaj zog antibacterial muaj peev xwm, ntau yam ntawm cov kab mob antibacterial; tsis muaj ntxhiab,; ntev dej tsis kam, lub sijhawm cia ntev; zoo thermal stability, tsis hloov xim ntawm qhov kub thiab txias, tsis muaj decomposition, tsis hais decomposition, tsis hais decomposition, tsis hais decomposition, tsis hais decomposition. Tsis txhob volatilize, tsis deteriorate; zoo instantability.
