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 4f uila uila o nano-CeO2 he mea maʻalahi loa ia i ka lawe ʻana i ka māmā, a ʻo ka band absorption ka hapa nui ma ka ʻāpana ultraviolet (200-400nm), ʻaʻohe ona hiʻohiʻona hiʻona 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 waho e hoʻomaikaʻi i ka pale ʻana i ka wā, ʻoi aku hoʻi i nā huahana me nā koi ākea kiʻekiʻe e like me nā plastic transparent a nā varnish.

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

Ma muli o ka hoʻolālā uila kūikawā o waho o ka honua oxides, 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. pūhui honua laha ʻole. 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 ka mana o nā waiwai ʻē aʻe o MVQ vulcanizate ma 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 hoʻomākaukau ʻia e Galembeck A a me AlvesO L ua hoʻohana ʻia e like me nā mea uila, a ʻo Vijayakumar G a me nā mea ʻē aʻe i doped CeO2 nano i loko o ka vinylidene fluoride-hexafluoropropylene copolymer. Ua hoʻomākaukau ʻia ka lithium ion electrode material me ka maikaʻi ionic conductivity.
