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 ekukhanyeni ukukhanya, kwaye ibhendi yokufunxa ininzi kwingingqi 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. ilungiswe i-polyaniline / i-CeO2 i-nano-composite particles ene-core-shell structure, kwafunyaniswa ukuba ukuqhutyelwa kweengqungquthela ezidibeneyo kwanda ngokunyuka kwe-polyaniline / CeO2 i-molar ratio, kunye ne-degree of protonation ifikelele kwi-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 nezinye i-doped CeO2 nano kwi-vinylidene fluoride-hexafluoropropylene copolymer.I-lithium ion electrode impahla ene-ionic conductivity egqwesileyo ilungisiwe.
