Xa ukukhanya kwelanga kubetha umphezulu wento, into ubukhulu becala ifunxa amandla okukhanya akufutshane ne-infrared ukuze yonyuse ubushushu bomphezulu wayo, kwaye amandla okukhanya akufuphi ne-infrared athatha i-50% yamandla ewonke okukhanya kwelanga. Ehlotyeni, xa ilanga likhanya phezu kwento, ubushushu bomphezulu bunokufikelela kwi-70~80℃. Ngeli xesha, ukukhanya kwe-infrared kufuneka kubonakaliswe ukunciphisa ukushisa kwendawo; xa iqondo lobushushu lisezantsi ebusika, ukukhanya kwe-infrared kufuneka kudluliswe ukuze kugcinwe ubushushu. Okokuthi, kukho imfuneko yezinto ezihlakaniphile zokulawula ubushushu obunokubonakalisa ukukhanya kwe-infrared kumaqondo aphezulu, kodwa ukuhambisa ukukhanya kwe-infrared kumaqondo aphantsi kunye nokuhambisa ukukhanya okubonakalayo ngexesha elifanayo, ukwenzela ukugcina amandla nokukhusela indalo.
I-Vanadium diokside (VO2) yioksidi enomsebenzi wokutshintsha isigaba esikufutshane ne-68°C. Kucingelwa ukuba ukuba i-VO2 powder impahla kunye nomsebenzi wokutshintsha kwesigaba idityaniswe kwizinto ezisisiseko, kwaye emva koko ixutywe nezinye ii-pigments kunye nezizaliso, i-composite yokulawula ukushisa okuhlakaniphileyo yokulawula ubushushu ngokusekelwe kwi-VO2 inokwenziwa. Emva kokuba ubuso bento bufakwe ngolu hlobo lwepeyinti, xa ukushisa kwangaphakathi kuphantsi, ukukhanya kwe-infrared kungangena ngaphakathi; xa iqondo lokushisa liphakama kwiqondo lokushisa elibalulekileyo lokutshintsha, utshintsho lwesigaba luyenzeka, kwaye ukukhanya kwe-infrared kuyancipha kwaye ukushisa kwangaphakathi kuyancipha kancane kancane; Xa iqondo lobushushu lehla ukuya kubushushu obuthile, i-VO2 iphinda itshintshe, kwaye i-infrared light transmittance iyanda kwakhona, ngaloo ndlela iqonda ulawulo lobushushu obukrelekrele. Ingabonwa ukuba isitshixo sokulungiselela iingubo zokulawula ukushisa okuhlakaniphile kukulungiselela i-VO2 powder kunye nomsebenzi wokutshintsha isigaba.
Kwi-68℃, i-VO2 itshintsha ngokukhawuleza ukusuka kwi-semiconductor yobushushu obuphantsi, i-antiferromagnetic, kunye ne-MoO2-efana ne-mooclinic egqwethekileyo isigaba ukuya kwinqanaba eliphezulu lobushushu besinyithi, i-paramagnetic, kunye nesigaba se-rutile tetragonal, kunye ne-VV yangaphakathi yokutshintsha ibhondi Yibhondi yentsimbi. , ebonisa imeko yesinyithi, i-conduction ye-electronics yasimahla iphuculwe kabukhali, kwaye iipropathi zokukhanya ziyatshintsha. ngokubalulekileyo. Xa iqondo lobushushu liphezulu kunendawo yokutshintsha kwesigaba, i-VO2 ikwimeko yesinyithi, indawo yokukhanya ebonakalayo ihlala elubala, indawo yokukhanya kwe-infrared ibonakalisa kakhulu, kwaye indawo yokukhanya kwe-infrared yemitha yelanga ivalwe ngaphandle, kunye nokuhanjiswa kwe-infrared. ukukhanya kwe-infrared kuncinci; Xa inqaku litshintsha, i-VO2 ikwimeko ye-semiconductor, kwaye ummandla ukusuka ekukhanyeni okubonakalayo ukuya ekukhanyeni kwe-infrared kukhanya ngokuphakathi, okuvumela ukuba uninzi lwemitha yelanga (kubandakanywa ukukhanya okubonakalayo kunye nokukhanya kwe-infrared) ukungena kwigumbi, kunye nokuhanjiswa okuphezulu, kwaye olu tshintsho buyela umva.
Ukusetyenziswa okusebenzayo, iqondo lobushushu besigaba se-68 ° C lisephezulu kakhulu. Indlela yokunciphisa ubushushu besigaba sokutshintsha kwiqondo lokushisa yingxaki ekhathalelwa ngumntu wonke. Okwangoku, eyona ndlela ichanekileyo yokunciphisa ubushushu benguqu yesigaba yi-doping.
Okwangoku, uninzi lweendlela zokulungiselela i-VO2 ye-doped yi-doping eyodwa, oko kukuthi, i-molybdenum okanye i-tungsten kuphela i-doped, kwaye kukho iingxelo ezimbalwa kwi-doping ngaxeshanye yezinto ezimbini. I-Doping izinto ezimbini ngexesha elifanayo azikwazi ukunciphisa kuphela ubushushu benguqu yesigaba, kodwa nokuphucula ezinye iimpawu zepowder.
