Iav tshav kub rwb thaiv tsev txheej yog txheej txheej npaj los ntawm kev ua ib lossis ob peb cov ntaub ntawv nano-hmoov.Cov khoom siv nano-cov khoom siv muaj cov khoom siv kho qhov muag tshwj xeeb, uas yog, lawv muaj qhov cuam tshuam loj hauv thaj chaw infrared thiab ultraviolet, thiab muaj kev xa tawm siab hauv thaj chaw pom lub teeb.Siv cov pob tshab kub rwb thaiv tsev cov khoom ntawm cov khoom, nws yog tov nrog ib puag ncig-phooj ywg zoo resins, thiab ua tiav los ntawm cov txheej txheem tshwj xeeb los npaj lub zog-txuag thiab ib puag ncig-phooj ywg cua sov-insulating txheej.Raws li qhov kev pom zoo tsis cuam tshuam rau lub iav teeb pom kev zoo, nws ua tiav cov txiaj ntsig ntawm kev txuag hluav taws xob thiab cua txias rau lub caij ntuj sov, thiab txuag hluav taws xob thiab txuag hluav taws xob thaum lub caij ntuj no.

Nyob rau hauv xyoo tas los no, tshawb nrhiav hom tshiab ntawm ib puag ncig zoo thermal rwb thaiv tsev cov ntaub ntawv yeej ib txwm yog lub hom phiaj nrhiav los ntawm cov kws tshawb fawb.Cov ntaub ntawv no muaj cov ntawv thov dav dav hauv thaj chaw ntsuab lub tsev txuag hluav taws xob thiab tsheb iav hluav taws xob rwb thaiv tsev-nano hmoov thiab cov ntaub ntawv ua haujlwm zoo uas muaj qhov pom kev pom lub teeb pom kev zoo thiab tuaj yeem nqus tau lossis cuam tshuam lub teeb ze-infrared.Ntawm no peb tsuas yog qhia cov cesium tungsten bronze nanoparticles.

Raws li cov ntaub ntawv tseem ceeb, cov yeeb yaj kiab pob tshab xws li indium tin oxide (ITOs) thiab cov yeeb yaj kiab antimony-doped tin oxide (ATOs) tau siv rau hauv cov ntaub ntawv rwb thaiv tsev pob tshab, tab sis lawv tsuas tuaj yeem thaiv lub teeb ze-infrared nrog wavelengths ntau dua 1500nm.Cesium tungsten bronze (CsxWO3, 0＜x＜1) muaj siab pom lub teeb transmittance thiab muaj peev xwm nqus tau lub teeb nrog wavelengths ntau dua 1100nm.Qhov ntawd yog hais tias, piv nrog ATOs thiab ITOs, cesium tungsten bronze muaj kev hloov xim xiav nyob rau hauv nws qhov ze-infrared nqus ncov, yog li nws tau nyiam ntau thiab ntau dua.

Cesium tungsten tooj liab nanoparticlesmuaj qhov siab siab ntawm cov nqa khoom pub dawb thiab cov khoom siv kho qhov muag tshwj xeeb.Lawv muaj kev xa tawm siab nyob rau thaj tsam pom lub teeb thiab muaj zog tiv thaiv cov nyhuv hauv thaj tsam ze-infrared.Nyob rau hauv lwm yam lus, cesium tungsten bronze cov ntaub ntawv, xws li cesium tungsten bronze pob tshab tshav kub-insulating txheej, tuaj yeem ua kom pom lub teeb pom kev zoo (tsis cuam tshuam rau lub teeb pom kev zoo) thiab tuaj yeem tiv thaiv feem ntau ntawm cov cua sov coj los ntawm ze-infrared teeb.Kev nqus coefficient α ntawm ntau tus neeg nqa khoom pub dawb nyob rau hauv cesium tungsten bronze system yog proportional rau cov cab kuj dawb concentration thiab square ntawm lub wavelength ntawm lub teeb absorbed, yog li thaum cov ntsiab lus cesium hauv CsxWO3 nce, qhov concentration ntawm cov cab kuj dawb hauv lub kaw lus maj mam nce, qhov kev nqus tau zoo nyob rau hauv cheeb tsam ze-infrared yog pom tseeb dua.Hauv lwm lo lus, qhov ze-infrared shielding kev ua tau zoo ntawm cesium tungsten bronze nce raws li nws cov ntsiab lus cesium nce.
