Tšebeliso ea nano cerium oxide ka polymer

Nano-ceria e ntlafatsa ho hanyetsa botsofali ba ultraviolet ea polymer.

 

Sebopeho sa elektroniki sa 4f sa nano-CeO2 se na le kutloelo-bohloko haholo ho monyeng ha leseli, 'me sehlopha sa ho monya hangata se sebakeng sa ultraviolet (200-400nm), se se nang mokhoa oa ho monya leseli le bonahalang le phetiso e ntle. E tloaelehileng ea ultramicro CeO2 e sebelisetsoang ho monya mahlaseli a kotsi e se e sebelisitsoe indastering ea khalase: CeO2 ultramicro powder e nang le boholo ba likaroloana tse ka tlaase ho 100nm e na le bokhoni bo botle ba ho monya mahlaseli a kotsi le phello ea tšireletso, e ka sebelisoa ka fiber ea letsatsi, khalase ea koloi, pente, litlolo, filimi, polasetiki le lesela, joalo-joalo E ka sebelisoa ka ntle pepenene dihlahiswa ho ntlafatsa boemo ba leholimo ho hanyetsa, haholo-holo ka dihlahiswa le pepeneneng phahameng. litlhoko tse kang li-plastiki tse bonaletsang le li-varnish.

 

 

Nano-cerium oxide e ntlafatsa botsitso ba mocheso oa polymer.

 

Ka lebaka la sebopeho se ikhethileng sa ka ntle sa elektroniki sa li-oxide tsa lefatše tse sa tloaelehang, li-oxide tsa lefatše tse sa tloaelehang joalo ka CeO2 li tla ama botsitso ba mocheso oa li-polymer tse ngata, joalo ka PP, PI, Ps, nylon 6, epoxy resin le SBR, e ka ntlafatsoang ka ho eketsa. metsoako ea lefatše e sa tloaelehang. Peng Yalan et al. o fumane hore ha o ithuta tšusumetso ea nano-CeO2 ho tsitsipano ea mocheso oa methyl ethyl silicone rabara (MVQ), Nano-CeO2 _2 e ka ntlafatsa ka ho hlaka ho hanyetsa mocheso oa moea oa mocheso oa MVQ vulcanizate. Ha tekanyo ea nano-CeO2 e le 2 phr, thepa e meng ea MVQ vulcanizate ha e na tšusumetso e fokolang ho ZUi, empa ho hanyetsa mocheso oa eona ZUI ho molemo.

Nano-cerium oxide e ntlafatsa conductivity ea polymer

 

Ho kenyelletsoa ha nano-CeO2 ho li-polymers tse tsamaisang ho ka ntlafatsa thepa e 'ngoe ea thepa ea conductive, e nang le boleng bo ka sebelisoang indastering ea elektroniki. Li-polymers tsa conductive li na le ts'ebeliso e ngata lisebelisoa tse fapaneng tsa elektroniki, joalo ka libeteri tse nchafalitsoeng, li-sensor tsa lik'hemik'hale joalo-joalo. Polyaniline ke e 'ngoe ea li-polymers tsa conductive tse nang le makhetlo a mangata a sebelisoang.E le hore e ntlafatse thepa ea eona ea' mele le ea motlakase, e kang conductivity ea motlakase, thepa ea magnetic le photoelectronics, polyaniline e atisa ho kopanngoa le likarolo tse sa tloaelehang ho etsa li-nanocomposites. Liu F le ba bang ba lokiselitse letoto la li-composite tsa polyaniline/nano-CeO2 tse nang le litekanyo tse fapaneng tsa molar ka in-situ polymerization le doping hydrochloric acid. Chuang FY et al. ho lokiselitsoe likaroloana tsa polyaniline / CeO2 nano-composite tse nang le sebopeho sa khetla ea mantlha, ho ile ha fumanoa hore conductivity ea likaroloana tse kopantsoeng e eketsehile ka keketseho ea polyaniline / CeO2 molar ratio, 'me tekanyo ea protonation e fihlile hoo e ka bang 48.52%. Nano-CeO2 e boetse e thusa ho li-polymer tse ling tse tsamaisang. CeO2/ polypyrrole composite tse lokiselitsoeng ke Galembeck A le AlvesO L li sebelisoa e le lisebelisoa tsa elektronike, 'me Vijayakumar G le ba bang ba doped CeO2 nano ka vinylidene fluoride-hexafluoropropylene copolymer.Thepa ea lithium ion electrode e nang le conductivity e ntle ea ionic e lokiselitsoe.
