Imisebe ye-Ultraviolet ingenye yezingxenye ezibalulekile zokukhanya kwelanga, futhi ubude bayo begagasi bungahlukaniswa ngamabhande amathathu. Phakathi kwazo, i-UVC iyigagasi elifushane, elimuncwa futhi livinjwe ungqimba lwe-ozone, alikwazi ukufinyelela phansi, futhi alinawo umphumela olimazayo emzimbeni womuntu. Ngakho-ke, i-UVA ne-UVB emisebeni ye-ultraviolet zingamabhande amaza amakhulu adala umonakalo esikhumbeni somuntu.

Izindawo zokuhlala e-Hongwu Nanotitanium dioxide (TiO2) nanopowderinosayizi wezinhlayiya ezincane, umsebenzi ophezulu, izakhiwo eziphakeme zokuphinda ziphinde ziphinde ziphinde futhi zibe nesithombe esiphezulu. Ayikwazi ukukhombisa kuphela futhi ihlakaze imisebe ye-ultraviolet, kodwa futhi iyincele, ngaleyo ndlela ibe namandla okuvimba aqinile ngokumelene nemisebe ye-UV. Kuyisivikelo somzimba esithembisayo se-UV esisebenza kahle kakhulu.

Ikhono le-anti-UV le-nano TiO2 lihlobene nosayizi wezinhlayiyana zayo. Uma usayizi wezinhlayiyana ze-titanium dioxide nanoparticle ingu-≤300nm, imisebe ye-ultraviolet enobude obuphakathi kuka-190 no-400nm iboniswa ngokuyinhloko futhi ihlakazeke; lapho usayizi wezinhlayiyana ze-titania nanopowder ingu-<200nm, ukumelana ne-UV kubonakala kakhulu futhi kuhlakazeke. Indlela yokuvikela ilanga yemisebe ye-ultraviolet ezindaweni ezimaphakathi namagagasi namagagasi amade iyisembozo esilula, futhi ikhono lokuvikela ilanga libuthakathaka; lapho ubukhulu bezinhlayiyana ze-TiO2 nano powder buphakathi kuka-30 no-100nm, ukumuncwa kwemisebe ye-ultraviolet endaweni yamagagasi aphakathi kuthuthukiswa kakhulu, futhi umphumela wokuvikela emisebeni ye-ultraviolet ungcono kakhulu. Nokho, indlela yayo yokuvikela ilanga iwukumunca imisebe ye-ultraviolet.

Ngamafuphi,i-titanium dioxide nano particleinezindlela ezihlukene zokuvikela ilanga zamaza ahlukene emisebe ye-ultraviolet. Uma ubude begagasi bemisebe ye-ultraviolet bubude ngokuqhathaniswa, ukusebenza kokuvikela kwe-nano titanium dioxide TiO2 kuncike ekhonweni layo lokuhlakaza; lapho ubude begagasi bemisebe ye-ultraviolet bufushane, ukusebenza kwayo okuyisivikelo kuncike ekhonweni layo lokumunca. Okusho ukuthi, ikhono le-nano titanium oxide lokuvikela imisebe ye-ultraviolet linqunywa kokubili amandla ayo okumunca namandla okuhlakazeka. Uma umncane usayizi wezinhlayiyana oyinhloko, amandla okumunca i-UV aqina ama-nano titanium dioxide powders.

Ukuhlola kubonisa ukuthi i-nano rutile titanium dioxide ye-Hongwu Nano i-TiO2 inezinto ezingcono zokuvikela i-UV kune-nano anatase TiO2. I-Nano TiO2 inamathuba amahle okusebenza ekuqedeni ukulwa ne-UV kwezindwangu zikakotini nasezimbotsheni ezilwa nemisebe ye-ultraviolet engilazini evikelayo.
