Girazi kupisa kupisa kwekuputira ijasi rakagadzirwa nekugadzirisa imwe kana akati wandei nano-upfu zvinhu.Iwo nano-materials anoshandiswa ane special optical properties, kureva kuti, ane high barrier rate in the infrared and ultraviolet regions, uye high transmittance munzvimbo inooneka chiedza.Uchishandisa iyo yakajeka yekupisa yekupisa midziyo yezvinhu, inosanganiswa neyakavhurika-inoshamwaridzika yakakwirira-inoshanda resins, uye inogadziriswa nehunyanzvi hwekugadzirisa tekinoroji kugadzirira kuchengetedza-simba uye zvakatipoteredza-hushamwari kupisa-kupisa machira.Pasi pechikonzero chekusakanganisa mwenje wegirazi, yakawana simba rekuchengetedza uye kutonhora muzhizha, uye kuchengetedza simba nekuchengetedza kupisa munguva yechando.

Mumakore achangopfuura, kuongorora mhando nyowani dzezvakatipoteredza zvine hushamwari hwekudziya kupisa zvinhu zvagara chiri chinangwa chinoteverwa nevaongorori.Zvishandiso izvi zvine tarisiro yakafara kwazvo yekushandiswa muminda yegirini yekuvaka simba rekuchengetedza uye mota yegirazi kupisa insulation-nano poda uye inoshanda firimu zvinhu zvine yakakwirira inooneka mwenje transmittance uye inogona kunyatso tora kana kuratidza pedyo-infrared mwenje.Pano isu tinonyanya kuunza cesium tungsten bronze nanoparticles.

Zvinoenderana nemagwaro akakodzera, mafirimu akajeka ekuitisa senge indium tin oxide (ITOs) uye antimony-doped tin oxide (ATOs) mafirimu akashandiswa mumagetsi ekudzivirira kupisa, asi anogona chete kuvhara pedyo-infrared mwenje newavelengths yakakura kupfuura 1500nm.Cesium tungsten bhuronzi (CsxWO3, 0<x<1) ine mwenje wepamusoro unooneka transmittance uye inokwanisa kubata mwenje zvine simba nemasaisai makuru kupfuura 1100nm.Kureva kuti, zvichienzaniswa neATOs neITOs, cesium tungsten bhuronzi ine bhurawu rinochinja padyo ne-infrared absorption peak, saka yakwezva kutarisisa kwakawanda.

Cesium tungsten bronze nanoparticlesiva nehupamhi hwepamusoro hwevatakuri vemahara uye yakasarudzika optical properties.Vane high transmittance munharaunda yechiedza inooneka uye yakasimba shielding effect munharaunda iri pedyo-infrared.Mune mamwe mazwi, cesium tungsten bhuronzi zvinhu, senge cesium tungsten bhuronzi transparent heat-insulating coatings, inogona kuve nechokwadi chekutaridzika kwechiedza chinooneka transmittance (pasina kukanganisa mwenje) uye inogona kudzivirira kwakawanda kwekupisa kunounzwa nepedyo-infrared mwenje.Iyo yekunyudza coefficient α yehuwandu hukuru hwevatakuri vemahara mu cesium tungsten bronze system inoenderana neyemahara mutakuri concentration uye sikweya yewavelength yechiedza chakanyungudutswa, saka kana iyo cesium yemukati muCsxWO3 ichiwedzera, kuwanda kwevatakuri vemahara mukati. iyo sisitimu inowedzera zvishoma nezvishoma, iyo yekuwedzera yekunyura munharaunda yepedyo-infrared inova pachena.Mune mamwe mazwi, iyo iri pedyo-infrared shielding performance ye cesium tungsten bronze inowedzera sezvo cesium yemukati inowedzera.
