Imitha ye-Ultraviolet yenye yezinto ezibalulekileyo zokukhanya kwelanga, kwaye ubude bayo bunokwahlulwa babe ngamaqela amathathu. Phakathi kwabo, i-UVC yi-wave emfutshane, efuntshwa kwaye ivalwe yi-ozone layer, ayikwazi ukufikelela emhlabeni, kwaye ayinayo impembelelo eyingozi kumzimba womntu. Ke ngoko, i-UVA kunye ne-UVB kwimitha ye-ultraviolet zezona bhendi zamaza amaza ezidala umonakalo eluswini lomntu.

Hongwu Nano'stitanium dioxide (TiO2) nanopowderinomlinganiselo omncinci wamasuntswana, umsebenzi ophezulu, iipropathi eziphezulu ze-refractive kunye ne-photoactivity ephezulu. Ayinakubonisa kuphela kwaye isasaze imitha ye-ultraviolet, kodwa iyayifunxa, ngaloo ndlela inamandla okuthintela imitha ye-UV. Sisikhuseli esithembisayo somzimba se-UV esisebenza kakuhle.

Ikhono lokuchasana ne-UV le-nano TiO2 lihambelana nobukhulu bayo be-particle. Xa ubukhulu be-particle ye-titanium dioxide nanoparticle yi-≤300nm, imisebe ye-ultraviolet ene-wavelengths phakathi kwe-190 kunye ne-400nm ibonakaliswe kwaye ihlakazeke; xa ubukhulu be-particle ye-titania nanopowder <200nm, ukuchasana kwe-UV kubonakaliswe kwaye kuhlakazeke. Indlela yokukhusela ilanga yemisebe ye-ultraviolet kwindawo ephakathi kwamaza kunye namaza amaza emide isigqubuthelo esilula, kwaye amandla okukhusela ilanga abuthathaka; xa ubukhulu be-particle ye-TiO2 nano powder buphakathi kwe-30 kunye ne-100nm, ukuxutywa kwemisebe ye-ultraviolet kwingingqi ye-medium-wave kuphuculwe kakhulu, kwaye umphumo wokukhusela kwimisebe ye-ultraviolet iyona nto ibhetele. Kaloku, indlela yokukhusela ilanga kukufunxa imitha yeultraviolet.

Ukushwankathela,isuntswana le-titanium dioxide nanoineendlela ezahlukeneyo zokukhusela ilanga kumaza ahlukeneyo emitha ye-ultraviolet. Xa ubude bemitha ye-ultraviolet bude bubude, ukusebenza kokukhusela kwe-nano titanium dioxide TiO2 kuxhomekeke kwikhono layo lokusabalalisa; xa ubude bemitha ye-ultraviolet bufutshane, ukusebenza kwayo kokukhusela kuxhomekeke kubuchule bayo bokufunxa. Oko kukuthi, ukukwazi kwe-nano titanium oxide ukukhusela imitha ye-ultraviolet kumiselwa ngamandla ayo okufunxa kunye nomthamo wokusasazeka. Okukhona kuncinci ubungakanani bamasuntswana aphambili, kokukhona bomelele isakhono se-UV sokufunxa se-nano titanium dioxide engumgubo.

Iimvavanyo zibonisa ukuba i-Hongwu Nano's nano rutile titanium dioxide TiO2 ineepropati ezingcono zokukhusela i-UV kune-nano anatase TiO2. I-Nano TiO2 inamathuba amahle okusebenza kwi-anti-UV ekugqityweni kwamalaphu ekotoni kunye nakwiingubo ezichasene ne-ultraviolet kwiglasi yokugquma.
