Ukusetshenziswa kwe-nano cerium oxide ku-polymer
I-Nano-ceria ithuthukisa ukumelana nokuguga kwe-ultraviolet kwe-polymer.
Isakhiwo se-elekthronikhi se-4f se-nano-CeO2 sizwela kakhulu ekumunceni ukukhanya, futhi ibhande lokumunca ikakhulukazi lisendaweni ye-ultraviolet (200-400nm), engenakho ukumuncwa kwesici ekukhanyeni okubonakalayo kanye nokudluliswa okuhle. I-ultramicro CeO2 evamile esetshenziselwa ukumuncwa kwe-ultraviolet isivele isetshenziswa embonini yengilazi: I-CeO2 ultramicro powder enosayizi wezinhlayiyana ezingaphansi kuka-100nm inekhono elihle kakhulu lokumunca i-ultraviolet nomthelela wokuvikela, ingasetshenziswa ku-sunscreen fiber, ingilazi yemoto, upende, izimonyo, ifilimu, ipulasitiki nendwangu, njll. Ingasetshenziswa emikhiqizweni eveziwe yangaphandle ukuze kuthuthukiswe ukumelana nesimo sezulu, ikakhulukazi emikhiqizweni enezidingo eziphezulu zokubonisa izinto njengamapulasitiki asobala namavarnish.
I-Nano-cerium oxide ithuthukisa ukuzinza kokushisa kwe-polymer.
Ngenxa yesakhiwo esikhethekile se-elekthronikhi sangaphandle sama-oxides omhlaba angavamile, ama-oxide omhlaba angavamile njenge-CeO2 azothinta kahle ukuzinza okushisayo kwama-polymers amaningi, njenge-PP, i-PI, i-Ps, inayiloni 6, i-epoxy resin ne-SBR, engathuthukiswa ngokungeza. izinhlanganisela zomhlaba ezingavamile. Peng Yalan et al. ithole ukuthi lapho itadisha ithonya le-nano-CeO2 ekuzinzeni okushisayo kwe-methyl ethyl silicone rubber (MVQ), i-Nano-CeO2 _ 2 ngokusobala ingathuthukisa ukumelana nokuguga komoya wokushisa kwe-MVQ vulcanizate. Lapho umthamo we-nano-CeO2 ungu-2 phr, ezinye izakhiwo ze-MVQ vulcanizate zinethonya elincane ku-ZUi, kodwa ukumelana nokushisa kwayo i-ZUI kuhle.
I-Nano-cerium oxide ithuthukisa ukuqhutshwa kwe-polymer
Ukwethulwa kwe-nano-CeO2 kuma-polymers ahambayo kungathuthukisa ezinye izakhiwo zezinto zokwenziwa, ezinenani elingase lisetshenziswe embonini ye-elekthronikhi. Ama-polymers asebenzayo anokusetshenziswa okuningi kumishini ehlukahlukene ye-elekthronikhi, njengamabhethri aphinde ashajwe, izinzwa zamakhemikhali nokunye. I-Polyaniline ingenye yama-polymers aqhubayo anemvamisa ephezulu yokusetshenziswa.Ukuze kuthuthukiswe izakhiwo zayo ezingokomzimba nezikagesi, njengokuhamba kukagesi, izakhiwo kazibuthe kanye ne-photoelectronics, i-polyaniline ivame ukuhlanganiswa nezingxenye ezingaphili ukuze zenze ama-nanocomposites. U-Liu F nabanye balungise uchungechunge lwezinhlanganisela ze-polyaniline/nano-CeO2 ezinezilinganiso ezihlukene ze-molar by in-situ polymerization kanye ne-doping hydrochloric acid. UChuang FY et al. kulungiswe izinhlayiya ze-polyaniline / CeO2 nano-composite ezinokwakheka kwegobolondo eliwumgogodla, kwatholakala ukuthi ukuqhutshwa kwezinhlayiya eziyinhlanganisela kuyanda ngokwanda kwe-polyaniline / CeO2 molar ratio, kanti izinga le-protonation lifinyelele cishe ku-48.52%. I-Nano-CeO2 iyasiza nakwamanye ama-polymers conductive. Izinhlanganisela ze-CeO2/ polypyrrole ezilungiselelwe i-Galembeck A kanye ne-AlvesO L zisetshenziswa njengezinto zikagesi, kanti i-Vijayakumar G nabanye bafake i-CeO2 nano ku-vinylidene fluoride-hexafluoropropylene copolymer.Impahla ye-lithium ion electrode ene-ionic conductivity enhle kakhulu iyalungiswa.
