Kushandiswa kwe nano cerium oxide mu polymer
Nano-ceria inovandudza ultraviolet kuchembera kuramba kwepolymer.
Iyo 4f yemagetsi chimiro che nano-CeO2 inonzwa zvakanyanya pakunyura kwechiedza, uye bhendi rekunyudza rinonyanya munzvimbo ye ultraviolet (200-400nm), iyo isina hunhu hwekunyura kune inooneka chiedza uye yakanaka transmittance. Yakajairwa ultramicro CeO2 inoshandiswa kunyura ultraviolet yakatoshandiswa muindasitiri yegirazi: CeO2 ultramicro poda ine particle size isingasviki 100nm ine yakanyanya kunaka ultraviolet absorption kugona uye kudzivirira mhedzisiro, Inogona kushandiswa mu sunscreen fiber, girazi remota, pendi, zvizorwa, firimu, mapurasitiki uye machira, etc. Inogona kushandiswa muzvigadzirwa zvekunze zvakafumurwa kuvandudza mamiriro ekunze, kunyanya mune zvigadzirwa zvine kujeka kwakanyanya. zvinodiwa zvakadai semapurasitiki akajeka uye varnishes.
Nano-cerium oxide inovandudza kugadzikana kwekupisa kwepolymer.
Nekuda kweiyo yakakosha yekunze yemagetsi chimiro cheasingawanzo pasi oxides, isingawanzo pasi oxides seCeO2 ichakanganisa kugadzikana kwekupisa kwemapolymer mazhinji, akadai sePP, PI, Ps, nylon 6, epoxy resin uye SBR, inogona kuvandudzwa nekuwedzera. rare earth compounds. Peng Yalan et al. akawana kuti kana uchidzidza pesvedzero ye nano-CeO2 pane kugadzikana kwekudziya kwemethyl ethyl silicone rubber (MVQ), Nano-CeO2 _ 2 inogona zviri pachena kugadzirisa kupisa kwemhepo kuchembera kuramba kweMVQ vulcanizate. Kana iyo dosage ye nano-CeO2 iri 2 phr, zvimwe zvimiro zveMVQ vulcanizate zvine simba shoma paZUi, asi kupisa kwayo kupikisa ZUI kwakanaka.
Nano-cerium oxide inovandudza conductivity yepolymer
Iko kuunzwa kwe nano-CeO2 mune conductive mapolymers inogona kuvandudza zvimwe zvivakwa zve conductive zvinhu, izvo zvine mukana wekushandisa kukosha muindasitiri yemagetsi. Conductive mapolymers ane akawanda mashandisiro mumhando dzakasiyana dzemagetsi, senge mabhatiri anochajiswa, makemikari sensors uye zvichingodaro. Polyaniline ndeimwe yemapolymers anoitisa ane frequency yekushandiswa.Kuitira kuvandudza maitiro ayo emuviri nemagetsi, akadai semagetsi conductivity, magineti emhando uye photoelectronics, polyaniline inowanzosanganiswa neinorganic components kuita nanocomposites. Liu F nevamwe vakagadzira akatevedzana epolyaniline/nano-CeO2 macomposites ane akasiyana molar ratios ne-situ polymerization uye doping hydrochloric acid. Chuang FY et al. yakagadzirira polyaniline / CeO2 nano-composite particles ine core-shell structure, Zvakaonekwa kuti conductivity yezvikamu zvakasanganiswa yakawedzera nekuwedzera kwe polyaniline / CeO2 molar ratio, uye dhigirii ye protonation yakasvika inenge 48.52%. Nano-CeO2 inobatsirawo kune mamwe mapolymer conductive. CeO2/ polypyrrole composites yakagadzirwa naGalembeck A uye AlvesO L inoshandiswa sezvigadzirwa zvemagetsi, uye Vijayakumar G nevamwe doped CeO2 nano mu vinylidene fluoride-hexafluoropropylene copolymer.Iyo lithium ion electrode zvinhu zvine ionic conductivity yakanakisa inogadzirwa.
