Ka hoʻohana ʻana o ka nano cerium oxide i ka polymer

Hoʻomaikaʻi ʻo Nano-ceria i ke kūpaʻa ʻelemakule ultraviolet o ka polymer.

ʻO ka ʻōnaehana uila 4f o nano-CeO2 he mea maʻalahi loa ia i ka absorption māmā, a ʻo ka band absorption ka hapa nui ma ka ʻāpana ultraviolet (200-400nm), ʻaʻohe ona hiʻohiʻona ʻike i ka mālamalama ʻike a me ka transmittance maikaʻi.Ua hoʻohana mua ʻia ka ultramicro CeO2 maʻamau no ka absorption ultraviolet i ka ʻoihana aniani: ʻo CeO2 ultramicro pauka me ka nui o ka nui ma lalo o 100nm i ʻoi aku ka maikaʻi o ka ultraviolet absorption hiki a me ka hopena pale, Hiki ke hoʻohana ʻia i ka fiber sunscreen, aniani kaʻa, pena, nā mea hoʻonaninani, kiʻiʻoniʻoni, plastik a me ka lole, a me nā mea ʻē aʻe. Hiki ke hoʻohana ʻia i nā huahana i hōʻike ʻia i waho e hoʻomaikaʻi i ke kū ʻana o ka wā, ʻoi aku hoʻi i nā huahana me nā koi ākea kiʻekiʻe e like me nā plastic transparent a me nā varnish.

Hoʻonui ka Nano-cerium oxide i ka paʻa wela o ka polymer.

Ma muli o ke ʻano uila kūikawā o waho o nā oxides honua, e hoʻopilikia maikaʻi ʻia nā oxides honua e like me CeO2 i ka paʻa wela o nā polymers he nui, e like me PP, PI, Ps, nylon 6, epoxy resin a me SBR, hiki ke hoʻonui ʻia ma ka hoʻohui ʻana. nā mea hoʻohui honua.ʻO Peng Yalan et al.ʻike ʻia i ka wā e aʻo ai i ka mana o ka nano-CeO2 ma ke kūpaʻa wela o ka methyl ethyl silicone rubber (MVQ), Nano-CeO2 _ 2 hiki ke maopopo i ka hoʻomaikaʻi ʻana i ka ea wela o ka wā kahiko o ka MVQ vulcanizate.Inā he 2 phr ka nui o ka nano-CeO2, ʻoi aku ka liʻiliʻi o nā waiwai ʻē aʻe o ka MVQ vulcanizate i ka ZUi, akā maikaʻi kona pale wela ZUI.

Hoʻonui ka Nano-cerium oxide i ka conductivity o ka polymer

ʻO ka hoʻokomo ʻana o nano-CeO2 i loko o nā polymers conductive hiki ke hoʻomaikaʻi i kekahi mau waiwai o nā mea conductive, nona ka waiwai noi i ka ʻoihana uila.He nui ka hoʻohana ʻana o nā polymers conductive i nā ʻenehana uila like ʻole, e like me nā pihi rechargeable, nā ʻike kemika a pēlā aku.ʻO Polyaniline kekahi o nā polymers conductive me ke alapine kiʻekiʻe o ka hoʻohana ʻana. I mea e hoʻomaikaʻi ai i kona ʻano kino a me ka uila, e like me ka conductivity uila, nā waiwai magnetic a me nā photoelectronics, hoʻohui pinepine ʻia ka polyaniline me nā ʻāpana inorganic e hana i nā nanocomposites.Ua hoʻomākaukau ʻo Liu F a me nā mea ʻē aʻe i ka pūʻulu polyaniline/nano-CeO2 composites me nā lākiō molar like ʻole e ka polymerization in-situ a me ka doping hydrochloric acid.Chuang FY et al.hoomakaukau polyaniline /CeO2 nano-composite particles me ka core-shell structure,Ua ike ia ka conductivity o ka composite particles mahuahua me ka hoonui ana o ka polyaniline /CeO2 molar ratio, a me ke degere o ka protonation i hiki ma kahi o 48.52%.He kōkua pū ʻo Nano-CeO2 i nā polymers conductive ʻē aʻe.ʻO CeO2 / polypyrrole composites i hoʻomākaukauʻia e Galembeck A a me AlvesO L ua hoʻohanaʻia e like me nā mea uila, aʻo Vijayakumar G a me nā mea'ē aʻe i doped CeO2 nano i loko o ka vinylidene fluoride-hexafluoropropylene copolymer. Ua hoʻomākaukauʻia ka mea lithium ion electrode me ka maikaʻi ionic conductivity.
