Ukusetyenziswa kwe-nano cerium oxide kwi-polymer
I-Nano-ceria iphucula ukuchasana nokuguga kwe-ultraviolet yepolymer.
Isakhiwo se-elektroniki se-4f se-nano-CeO2 sithinteka kakhulu ekufakweni kokukhanya, kwaye ibhendi yokufunxa ininzi kwindawo ye-ultraviolet (200-400nm), engenakho ukufunxa uphawu ekukhanyeni okubonakalayo kunye nokuhanjiswa okulungileyo.I-Ultramicro CeO2 eqhelekileyo esetyenziselwa ukufunxa i-ultraviolet sele isetyenzisiwe kwishishini leglasi: I-CeO2 ultramicro powder enobungakanani besuntswana elingaphantsi kwe-100nm inamandla agqwesileyo okufunxa i-ultraviolet kunye nefuthe lokukhusela, Inokusetyenziswa kwifiber ye-sunscreen, iglasi yemoto, ipeyinti, izithambiso, ifilimu, iplastiki kunye nelaphu, njl. Ingasetyenziselwa kwiimveliso ezivezwayo zangaphandle zokuphucula ukuxhathisa imozulu, ngokukodwa kwiimveliso ezineemfuno eziphezulu ezicacileyo ezifana neeplastiki ezicacileyo kunye neevanishi.
I-Nano-cerium oxide iphucula ukuzinza kwe-thermal ye-polymer.
Ngenxa yesakhiwo esikhethekileyo se-elektroniki sangaphandle se-oksidi yomhlaba enqabileyo, ii-oxides zomhlaba ezinqabileyo ezifana ne-CeO2 ziya kuchaphazela ngokuqinisekileyo ukuzinza kwe-thermal yeepolymers ezininzi, ezifana ne-PP, i-PI, i-Ps, i-nylon 6, i-epoxy resin kunye ne-SBR, enokuphuculwa ngokudibanisa. iikhompawundi zomhlaba ezinqabileyo.UPeng Yalan et al.wafumanisa ukuba xa ufunda impembelelo ye-nano-CeO2 ekuzinzeni kwe-thermal ye-methyl ethyl silicone irabha (MVQ), i-Nano-CeO2 _ 2 ngokucacileyo inokuphucula ukumelana nokuguga komoya we-MVQ vulcanizate.Xa idosi ye-nano-CeO2 yi-2 phr, ezinye iipropati ze-MVQ vulcanizate zinempembelelo encinci kwi-ZUi, kodwa ukumelana nobushushu ZUI kulungile.
I-Nano-cerium oxide iphucula i-conductivity ye-polymer
Ukuqaliswa kwe-nano-CeO2 kwiipolymers eziqhubayo kunokuphucula ezinye iipropathi zezinto eziphathekayo, ezinokubaluleka kwesicelo kwishishini lombane.Iipolymers eziqhubayo zinosetyenziso oluninzi kwizixhobo zombane ezahlukeneyo, ezinje ngebhetri ezinokutshajwa kwakhona, izinzwa zekhemikhali njalo njalo.I-Polyaniline yenye yeepolymers eziqhubayo kunye nesantya esiphezulu sokusetyenziswa.Ukuze kuphuculwe iimpawu zayo zomzimba kunye nombane, ezifana ne-conductivity yombane, izakhiwo zamagnetic kunye ne-photoelectronics, i-polyaniline idla ngokudityaniswa kunye namacandelo e-inorganic ukwenza i-nanocomposites.U-Liu F kunye nabanye balungiselela uchungechunge lwee-polyaniline / nano-CeO2 ezihlanganisiweyo ezinemilinganiselo eyahlukeneyo ye-molar nge-in-situ polymerization kunye ne-doping hydrochloric acid.UChuang FY et al.ilungisiwe i-polyaniline / i-CeO2 i-nano-composite ye-nano-composite isakhiwo esingundoqo-igobolondo, kwafunyaniswa ukuba ukuqhutyelwa kweengqungquthela ezidibeneyo kwanda ngokunyuka kwe-polyaniline / CeO2 i-molar ratio, kunye ne-degree of protonation yafikelela malunga ne-48.52%.I-Nano-CeO2 iluncedo nakwezinye iipolymers eziqhubayo.I-CeO2 / ii-polypyrrole composite ezilungiselelwe nguGalembeck A kunye ne-AlvesO L zisetyenziswa njengezinto zombane, kunye ne-Vijayakumar G kunye nabanye bafake i-CeO2 nano kwi-vinylidene fluoride-hexafluoropropylene copolymer.I-lithium ion electrode material ene-ionic conductivity egqwesileyo ilungisiwe.
