Kukula ndi Kusinthika kwa Anti-Infrared Textile mu Gulu Lankhondo Lamakono.

Nmasiku ano, mayunifolomu amakono ndi makina obisala ankhondo a zinthu ndi nyumba amatha kuchita zambiri kuposa kungogwiritsa ntchito zojambula zomwe zimapangidwa mwapadera kuti zigwirizane ndi chilengedwe kuti zisamawonekere.

Zida zapadera zimathanso kupereka zowunikira motsutsana ndi ma radiation a infrared heat radiation (IR radiation).Mpaka pano, yakhala IR-absorbing vat utoto wa kubisa kusindikizira ambiri amaonetsetsa kuti ovala makamaka "wosaoneka" kwa CCD masensa pa zipangizo masomphenya usiku.Komabe, posachedwapa tinthu tating’ono tomwe timatha kuyamwa ndi utoto.

Monga gawo la kafukufuku wofufuza, (AiF No. 15598), asayansi ku Hohenstein Institute ku Bönnigheim ndi ITCF Denkendorf apanga mtundu watsopano wa nsalu za IR-absorbent.Pogwiritsa ntchito dosing (chophimba) kapena kupaka ulusi wamankhwala ndi nanoparticles wa indium tin oxide (ITO), kutentha kwa dzuwa kumatha kuyamwa bwino kwambiri kotero kuti kuwunika bwino kumatheka kusiyana ndi zojambula wamba zobisika.

ITO ndi semiconductor yowonekera yomwe imagwiritsidwanso ntchito, mwachitsanzo, pamawonekedwe a mafoni a m'manja.Chovuta kwa ochita kafukufuku chinali kumangiriza tinthu tating'ono ta ITO ku nsalu m'njira yoti panalibe zowononga pazinthu zina, monga chitonthozo chawo chakuthupi.Chithandizo pansalu chinayeneranso kupangidwa kuti zisathe kuchapa, kupaka ndi nyengo.

Kuti muwone momwe kuwunikira kwamankhwala a nsalu, kuyamwa, kutumiza ndi kuwunikira kunayesedwa mumtundu wa mafunde a 0.25 - 2.5 μm, mwachitsanzo, ma radiation a UV, kuwala kowoneka ndi pafupi ndi infrared (NIR).Kuwunika kwa NIR makamaka, komwe kuli kofunikira pazida zowonera usiku, kunali kwabwinoko poyerekeza ndi zitsanzo za nsalu zosasinthidwa.

Mukufufuza kwawo kowoneka bwino, gulu la akatswiri lidatha kugwiritsa ntchito chuma chaukadaulo komanso zida zamakono zowonera ku Hohenstein Institute.Izi zimagwiritsidwanso ntchito m'njira zina komanso pochita kafukufuku: mwachitsanzo, pa pempho la kasitomala, akatswiri amatha kuwerengera nsalu zoteteza UV (UPF) ndikuwonetsetsa kuti zofunikira zamtundu ndi kulolerana zili monga momwe zafotokozedwera muukadaulo waukadaulo. kutumiza.

Kutengera zotsatira za kafukufuku waposachedwa, m'mapulojekiti amtsogolo nsalu zokhala ndi IR-absorbent zidzakonzedwanso molingana ndi mphamvu zawo zowongolera kutentha ndi thukuta.Cholinga ndikuletsa ma radiation apafupi ndi apakati a IR, monga kutentha kochokera mthupi, kuti zisapangike, kotero kuti kuzindikira kumakhala kovuta kwambiri.Mwa kusunga njira za thupi m'thupi la munthu zikuyenda bwino momwe zingathere, nsaluzi zimathandizanso kuti asilikali azitha kuchita bwino kwambiri ngakhale pa nyengo yovuta kwambiri kapena akuvutika maganizo kwambiri.Ofufuzawa akupindula ndi zaka zambiri zomwe adakumana nazo ku Hohenstein Institute pakuwunika ndi kukhathamiritsa kwa nsalu zogwira ntchito.Izi zalowa m'njira zambiri zoyesera zovomerezeka padziko lonse lapansi zomwe gulu la akatswiri lingagwiritse ntchito pantchito yake.
