Aikace-aikacen nano cerium oxide a cikin polymer
Nano-ceria yana inganta juriyar tsufa na ultraviolet na polymer.
Tsarin lantarki na 4f na nano-CeO2 yana da matukar damuwa ga shayarwar haske, kuma ƙungiyar shayarwa ta kasance mafi yawa a cikin yankin ultraviolet (200-400nm), wanda ba shi da wani abu mai mahimmanci ga haske mai gani da kuma watsawa mai kyau.An riga an yi amfani da na yau da kullun ultramicro CeO2 da aka yi amfani da shi don shayarwar ultraviolet a cikin masana'antar gilashi: CeO2 ultramicro foda tare da girman barbashi ƙasa da 100nm yana da mafi kyawun ikon ɗaukar ultraviolet da tasirin kariya, Ana iya amfani dashi a cikin fiber na hasken rana, gilashin mota, fenti, kayan kwalliya, fim, filastik da masana'anta, da dai sauransu Ana iya amfani da shi a cikin samfuran da aka fallasa su don haɓaka juriya na yanayi, musamman a cikin samfuran da ke da buƙatun bayyanannu masu girma irin su robobi na zahiri da varnishes.
Nano-cerium oxide yana inganta yanayin zafi na polymer.
Saboda tsarin lantarki na musamman na ƙananan oxides na duniya, ƙananan oxides na duniya kamar CeO2 za su yi tasiri sosai ga kwanciyar hankali na yawancin polymers, kamar PP, PI, Ps, nailan 6, epoxy resin da SBR, wanda za'a iya inganta ta hanyar ƙarawa. rare ƙasa mahadi.Peng Yalan et al.gano cewa a lokacin da nazarin tasirin nano-CeO2 a kan thermal kwanciyar hankali na methyl ethyl silicone roba (MVQ), Nano-CeO2 _ 2 iya fili inganta zafi iska tsufa juriya na MVQ vulcanizate.Lokacin da adadin nano-CeO2 shine 2 phr, sauran kaddarorin MVQ vulcanizate ba su da tasiri kaɗan akan ZUi, amma juriya na zafi ZUI yana da kyau.
Nano-cerium oxide yana inganta halayen polymer
Gabatarwar nano-CeO2 a cikin polymers masu sarrafawa na iya inganta wasu kaddarorin kayan aiki, waɗanda ke da yuwuwar ƙimar aikace-aikacen a masana'antar lantarki.Polymers masu aiki suna da amfani da yawa a cikin na'urorin lantarki daban-daban, kamar batura masu caji, firikwensin sinadarai da sauransu.Polyaniline yana daya daga cikin polymers masu sarrafawa tare da yawan amfani da yawa.Domin inganta halayensa na jiki da na lantarki, irin su wutar lantarki, kaddarorin maganadisu da kuma photoelectronics, polyaniline sau da yawa yana haɗuwa tare da abubuwan da ba a haɗa su ba don samar da nanocomposites.Liu F da sauransu sun shirya jerin abubuwan haɗin polyaniline/nano-CeO2 tare da ma'auni daban-daban na molar ta hanyar polymerization a cikin wurin da kuma doping hydrochloric acid.Chuang FY et al.shirya polyaniline / CeO2 nano-composite barbashi tare da core-harsashi tsarin, An gano cewa conductivity na composite barbashi ya karu da karuwa da polyaniline / CeO2 molar rabo, da kuma mataki na protonation kai game da 48.52%.Nano-CeO2 kuma yana taimakawa ga sauran polymers masu ɗaukar nauyi.CeO2 / polypyrrole composites wanda Galembeck A da AlvesO L suka shirya ana amfani da su azaman kayan lantarki, kuma Vijayakumar G da sauransu sun doped CeO2 nano cikin vinylidene fluoride-hexafluoropropylene copolymer.An shirya kayan lantarki na lithium ion tare da kyakkyawan halayen ionic.
