Kana chiedza chezuva charova pamusoro pechinhu, chinhu chacho chinonyanya kutora simba rechiedza riri pedyo ne-infrared kuti chiwedzere tembiricha yacho, uye simba rechiedza riri pedyo ne-infrared rinotora 50% yesimba rose rechiedza chezuva.Muzhizha, kana zuva richipenya pamusoro pechinhu, tembiricha yepamusoro inogona kusvika 70 ~ 80 ℃.Panguva ino, infrared mwenje inoda kuratidzwa kuti ideredze tembiricha yepasi pechinhu;kana tembiricha yadzikira munguva yechando, mwenje we infrared unofanirwa kufambiswa kuitira kuchengetedza kupisa.Ndiko kuti, panodiwa hungwaru hunodzora tembiricha iyo inogona kuratidza infrared mwenje patembiricha yakakwira, asi kuendesa mwenje we infrared pakudziya kwakaderera uye kutumira chiedza chinooneka panguva imwe chete, kuitira kuchengetedza simba nekuchengetedza nharaunda.
Vanadium dioxide (VO2) ioxide ine phase change function pedyo ne68°C.Zvinogoneka kuti kana iyo VO2 poda zvinhu zvine chikamu chekuchinja basa yakasanganiswa mu base zvinhu, uyezve yakasanganiswa nemamwe pigment uye mafirita, inoumbwa nehungwaru yekudzora tembiricha yekupfeka yakavakirwa paVO2 inogona kugadzirwa.Mushure mokunge pamusoro pechinhu chacho chakaputirwa nemhando iyi yepende, kana kupisa kwemukati kwakaderera, chiedza che infrared chinogona kupinda mukati;apo tembiricha inokwira kune yakakosha chikamu chekuchinja tembiricha, shanduko yechikamu inoitika, uye infrared light transmittance inoderera uye tembiricha yemukati inoderera zvishoma nezvishoma;Kana tembiricha yadzikira kune imwe tembiricha, VO2 inopinda reverse chikamu shanduko, uye infrared light transmittance inowedzera zvakare, nekudaro inoona hungwaru kutonga tembiricha.Zvinogona kuonekwa kuti kiyi yekugadzirira yakangwara tembiricha yekudzora machira ndeye kugadzirira VO2 upfu nechikamu chekuchinja basa.
Pa68 ℃, VO2 inokurumidza kushanduka kubva kune yakaderera-tembiricha semiconductor, antiferromagnetic, uye MoO2-yakaita yakashatiswa rutile monoclinic phase kuenda kune yakakwirira-temperature metallic, paramagnetic, uye rutile tetragonal phase, uye yemukati VV covalent bond inoshanduka Isimbi chisungo. , ichipa chimiro chesimbi, conduction mhedzisiro yemaerekitironi emahara inokwidziridzwa zvakanyanya, uye maitiro ekuona anochinja zvakanyanya.Kana tembiricha yakakwira kupfuura chikamu chekuchinja, VO2 iri mune simbi, inooneka mwenje dunhu rinoramba rakajeka, infrared mwenje dunhu rinoratidza zvakanyanya, uye infrared mwenje chikamu chemwaranzi yezuva chakavharirwa kunze, uye kufambisa kwemhepo. infrared light idiki;Kana poindi yachinja, VO2 inenge iri semiconductor state, uye dunhu kubva kuchiedza chinooneka kuenda kuchiedza che infrared rinenge riripachena, zvichibvumira kuwanda kwemwaranzi yezuva (kusanganisira mwenje unooneka uye infrared mwenje) kupinda mukamuri, ine transmittance yakakwira, uye shanduko iyi ndeye. reversible.
Nezvishandiso zvinoshanda, tembiricha yechikamu che68°C ichiri yakanyanya kukwirisa.Maitiro ekudzikisa tembiricha yechikamu chekuchinja kune kamuri tembiricha idambudziko iro munhu wese ane hanya nazvo.Parizvino, nzira yakananga yekudzikisa tembiricha yekuchinja kwechikamu ndeye doping.
Parizvino, dzakawanda dzenzira dzekugadzira doped VO2 ndeye unitary doping, ndiko kuti, molybdenum kana tungsten chete inoiswa doped, uye kune mishumo mishoma pane imwe nguva doping yezvinhu zviviri.Doping zvinhu zviviri panguva imwe chete hazvigone kungodzikisa tembiricha yekuchinja kwechikamu, asi zvakare kuvandudza zvimwe zvinhu zvehupfu.
