Nano-ceria itezimbere ultraviolet gusaza ya polymer.
Imiterere ya 4f ya elegitoronike ya nano-CeO2 yunvikana cyane no kwinjiza urumuri, kandi umurongo winjiza ahanini uri mukarere ka ultraviolet (200-400nm), udafite uburyo bwo kwinjiza urumuri rugaragara no kohereza neza.Ubusanzwe ultramicro CeO2 ikoreshwa mu kwinjiza ultraviolet yamaze gukoreshwa mu nganda zikirahure: Ifu ya ultramicro ya CeO2 ifite ubunini buri munsi ya 100nm ifite ubushobozi buhebuje bwo kwinjiza ultraviolet ningaruka zo gukingira, Irashobora gukoreshwa muri fibre yizuba, ikirahure cyimodoka, amarangi, kwisiga, firime, plastike nigitambara, nibindi. Birashobora gukoreshwa mubicuruzwa byagaragaye hanze kugirango bitezimbere ikirere, cyane cyane mubicuruzwa bisabwa gukorera mu mucyo nka plastiki ibonerana na langi.
Nano-cerium oxyde itezimbere ubushyuhe bwa polymer.
Bitewe nuburyo bwihariye bwa elegitoronike yububiko bwa okiside yisi idasanzwe, okiside yisi idasanzwe nka CeO2 izagira ingaruka nziza kumyuka yubushyuhe bwa polymers nyinshi, nka PP, PI, Ps, nylon 6, epoxy resin na SBR, bishobora kunozwa mukongeraho isi idasanzwe.Peng Yalan n'abandi.basanze iyo wiga ingaruka za nano-CeO2 kumiterere yubushyuhe bwa methyl etyl silicone reberi (MVQ), Nano-CeO2 _ 2 birashobora kugaragara neza kunoza ubushyuhe bwikirere busa na MVQ vulcanizate.Iyo igipimo cya nano-CeO2 ari interuro 2, indi mico ya MVQ vulcanizate ntigira ingaruka nke kuri ZUi, ariko ubushyuhe bwayo ZUI nibyiza.
Okiside Nano-cerium itezimbere polimeri
Kwinjiza nano-CeO2 muri polymers ikora birashobora kunoza imitungo yibikoresho bitwara ibintu, bifite agaciro gakoreshwa mubikorwa bya elegitoroniki.Imiyoboro ya polymers ikoresha byinshi mubikoresho bya elegitoroniki bitandukanye, nka bateri zishishwa, ibyuma bifata imiti nibindi.Polyaniline ni imwe muri polymers zitwara ibintu hamwe ninshuro nyinshi zo gukoresha.Mu rwego rwo kunoza imiterere yumubiri nu mashanyarazi, nkumuyagankuba wamashanyarazi, ibintu bya magnetique hamwe nifoto ya elegitoroniki, polyaniline akenshi iba yongewemo nibintu bidafite umubiri kugirango ikore nanocomposite.Liu F hamwe nabandi bateguye urukurikirane rwa polyaniline / nano-CeO2 hamwe nibipimo bitandukanye bya polarike hamwe na polymerisation hamwe na acide hydrochloric.Chuang FY n'abandi.hateguwe polyaniline / CeO2 nano-igizwe nimbuto-shitingi, Byagaragaye ko ubwinshi bwibice bigize compte byiyongereye hamwe no kwiyongera kwa polyaniline / CeO2 molar, naho urugero rwa protonation rugera kuri 48.52%.Nano-CeO2 nayo ifasha izindi polymers ziyobora.CeO2 / polypyrrole yibigize byateguwe na Galembeck A na AlvesO L bikoreshwa nkibikoresho bya elegitoroniki, naho Vijayakumar G hamwe nabandi bahinduye CeO2 nano muri vinylidene fluoride-hexafluoropropylene copolymer. Ibikoresho bya lithium ion electrode hamwe nubushobozi bwiza bwa ionic byateguwe.
