Codsiga nano cerium oxide ee polymer

Nano-ceria waxay hagaajisaa iska caabbinta ultraviolet gabow ee polymer.

 

Qaab dhismeedka elektaroonigga ah ee 4f ee nano-CeO2 aad ayuu ugu nugul nuugista iftiinka, qaybta nuugista waxay inta badan ku jirtaa gobolka ultraviolet (200-400nm), taas oo aan lahayn nuugista sifo iftiinka muuqda iyo gudbinta wanaagsan.Caadiga ah ultramicro CeO2 loo isticmaalo nuugista ultraviolet ayaa mar hore lagu dabaqay warshadaha galaaska: CeO2 ultramicro budada leh cabbirka qayb ka yar 100nm wuxuu leeyahay awood nuugista ultraviolet aad u fiican iyo saamaynta ilaalinta filim, balaastiig iyo dhar, iwm. Waxaa loo isticmaali karaa alaabta bannaanka bannaanka ah si loo hagaajiyo caabbinta cimilada, gaar ahaan alaabooyinka leh shuruudaha daahfurnaanta sare sida bacaha iyo faashashka hufan.

 

 

Nano-cerium oxide waxay wanaajisaa xasiloonida kulaylka ee polymerka.

 

Iyada oo ay ugu wacan tahay qaab-dhismeedka elektiroonigga ah ee gaarka ah ee oksaydhyada dhulka dhifka ah, oksaydhyada dhulka dhifka ah sida CeO2 ayaa si togan u saameyn doona xasilloonida kulaylka polymers badan, sida PP, PI, Ps, naylon 6, resin epoxy iyo SBR, kuwaas oo lagu wanaajin karo iyada oo lagu daro. isku dhafka dhulka naadir.Peng Yalan iyo al.ayaa la ogaaday in marka la baranayo saamaynta nano-CeO2 ee xasiloonida kulaylka ee methyl ethyl silicone rubber (MVQ), Nano-CeO2 _ 2 waxay si cad u hagaajin kartaa caabbinta hawada kulaylka gabowga ee MVQ vulcanizate.Marka qiyaasta nano-CeO2 ay tahay 2 phr, sifooyinka kale ee MVQ vulcanizate ayaa saameyn yar ku leh ZUi, laakiin caabbinta kulaylka ZUI waa mid wanaagsan.

Nano-cerium oxide waxay wanaajisaa habaynta polymer-ka

 

Soo bandhigida nano-CeO2 ee polymers-ka-dhaqdhaqaaqa waxay wanaajin kartaa qaar ka mid ah sifooyinka qalabka wax-qabadka, kuwaas oo leh qiimo codsi oo suurtagal ah warshadaha elektiroonigga ah.Polymers-ka wax-qabadka leh waxay leeyihiin adeegsiyo badan oo loo adeegsado aaladaha elektiroonigga ah ee kala duwan, sida baytariyada dib-u-dallaci kara, dareemayaasha kiimikada iyo wixii la mid ah.Polyaniline waa mid ka mid ah polymers-ka wax-qabadka leh ee isticmaalka joogtada ah ee isticmaalka.Liu F iyo kuwa kale waxay diyaariyeen taxane ah polyaniline/nano-CeO2 isku-dhafan oo leh saamiyo molar oo kala duwan iyadoo goobta ku jirta polymerization iyo doping hydrochloric acid.Chuang FY iyo al.polyaniline / CeO2 nano-composite particles oo leh qaab-dhismeedka qolof-core, Waxaa la ogaaday in korantada qaybaha isku-dhafka ah ay kordheen korodhka saamiga polyaniline / CeO2 molar, iyo heerka protonation wuxuu gaadhay 48.52%.Nano-CeO2 ayaa sidoo kale waxtar u leh polymers-ka kale ee wax-qabadka.Isku-dhafka CeO2/polypyrrole ee ay diyaariyeen Galembeck A iyo AlvesO L ayaa loo isticmaalaa sida qalabka elektarooniga ah, iyo Vijayakumar G iyo kuwa kale waxay ku dhejiyeen CeO2 nano oo ku dhejiyay vinylidene fluoride-hexafluoropropylene copolymer. Qalabka lithium ion electrode oo leh koronto ionic aad u fiican ayaa la diyaariyey.
