Ngwa nke nano cerium oxide na polymer
Nano-ceria na-eme ka nguzogide ịka nká ultraviolet nke polymer.
Usoro eletrọnịkị 4f nke nano-CeO2 na-enwe mmetụta nke ukwuu maka nnabata ọkụ, yana eriri absorption na-abụkarị na mpaghara ultraviolet (200-400nm), nke na-enweghị njirimara absorption na ìhè a na-ahụ anya na nnyefe dị mma. Nkịtị ultramicro CeO2 eji ultraviolet absorption etinyeworị na ụlọ ọrụ iko: CeO2 ultramicro ntụ ntụ nwere urughuru nha na-erughị 100nm nwere ikike nnabata ultraviolet kacha mma na mmetụta nchebe, enwere ike iji ya na eriri sunscreen, iko ụgbọ ala, agba, ihe ịchọ mma, ihe nkiri, plastik na akwa, wdg. Enwere ike iji ya na ngwaahịa ndị ekpughere n'èzí iji melite nguzogide ihu igwe, karịsịa na ngwaahịa ndị nwere nnukwu nghọta chọrọ dị ka plastik transperent na varnishes.
Nano-cerium oxide na-eme ka nkwụsi ike okpomọkụ nke polymer dị mma.
N'ihi usoro eletrọnịkị pụrụ iche nke ụwa oxides na-adịghị ahụkebe, oxides ụwa dị ụkọ dị ka CeO2 ga-emetụta nkwụsi ike nke okpomọkụ nke ọtụtụ polymers, dị ka PP, PI, Ps, nylon 6, epoxy resin na SBR, nke enwere ike imeziwanye site na ịgbakwunye. obere ogige ụwa. Peng Yalan et al. chọpụtara na mgbe ị na-amụ mmetụta nke nano-CeO2 na thermal kwụsie ike nke methyl ethyl silicone roba (MVQ), Nano-CeO2 _ 2 nwere ike doro anya melite okpomọkụ ikuku ịka nká iguzogide MVQ vulcanizate. Mgbe usoro onunu ogwu nke nano-CeO2 bụ 2 phr, ihe ndị ọzọ nke MVQ vulcanizate enwechaghị mmetụta na ZUi, mana okpomọkụ ya na-eguzogide ZUI dị mma.
Nano-cerium oxide na-eme ka nrụpụta polymer dị mma
Iwebata nano-CeO2 n'ime polymer conductive nwere ike imeziwanye ụfọdụ ihe eji eme ihe, nke nwere uru ngwa na ụlọ ọrụ eletrọnịkị. Ndị polymer na-arụ ọrụ nwere ọtụtụ ihe eji eme ihe na ngwaọrụ eletrọnịkị dị iche iche, dịka batrị enwere ike ịgbanye, ihe mmetụta kemịkalụ na ihe ndị ọzọ. Polyaniline bụ otu n'ime ihe ndị na-emepụta ihe na-emepụta ihe na-eme ka ọ dịkwuo elu. Iji meziwanye ihe anụ ahụ na ọkụ eletrik, dị ka eletriki eletrik, ihe magnetik na fotoelectronics, polyaniline na-ejikọta ya na ihe ndị na-emepụta ihe na-emepụta nanocomposites. Liu F na ndị ọzọ kwadebere usoro ihe mejupụtara polyaniline/nano-CeO2 nwere oke molar dị iche iche site na polymerization na ọnọdụ na doping hydrochloric acid. Chuang FY et al. akwadoro polyaniline / CeO2 nano-composite particles na isi-shell Ọdịdị, Achọpụtara na conductivity nke ihe mejupụtara ahụ mụbara na mmụba nke polyaniline / CeO2 molar ratio, na ogo nke protonation ruru banyere 48.52%. Nano-CeO2 na-enyekwara ndị polima ndị ọzọ aka. A na-eji CeO2 / polypyrrole composites nke Galembeck A na AlvesO L kwadebere dị ka ihe elektrọnik, na Vijayakumar G na ndị ọzọ doped CeO2 nano n'ime vinylidene fluoride-hexafluoropropylene copolymer. A na-akwadebe ihe electrode lithium ion nke nwere ezigbo ionic conductivity.
