9,9-Bis(3,4-dicarboxyphenyl)fluorene Dianhydride/BPAF cas:135876-30-1

Kufotokozera Kwachidule:

9,9-bis(3,4-dicarboxyphenyl)fluorene dioic anhydride, yomwe imadziwika kuti BDFA, ndi mankhwala omwe ali ndi mamolekyu a C32H14O6.Ndi mamolekyu olemera a 494.45 g/mol, mankhwalawa amadziwika ndi kukhazikika kwake kwapadera, malo osungunuka kwambiri, komanso kusungunuka kwapamwamba mu zosungunulira zosiyanasiyana za organic.

BDFA imagwiritsidwa ntchito kwambiri ngati gawo lofunikira pakuphatikizika kwa ma polima ochita bwino kwambiri ndi zida.Kapangidwe kake kapadera ka maselo, kopangidwa ndi mphete ziwiri za benzene zomata pamsana wa fluorene, zimapereka mawonekedwe otenthetsera komanso amakina pama polima omwe amabwera.

Kukhazikika kwapadera kwamafuta opangidwa ndi ma polima opangidwa ndi BDFA kumawalola kupirira kutentha kwambiri, kuwapangitsa kukhala oyenera kugwiritsidwa ntchito m'mafakitale apamlengalenga, magalimoto, ndi zamagetsi.Ma polima awa amawonetsa kukana kutentha, kuwala kwa UV, komanso dzimbiri lamankhwala, kuwonetsetsa kuti amakhala ndi moyo wautali komanso wokhazikika m'malo ovuta.

Kuphatikiza apo, ma polima opangidwa ndi BDFA ali ndi zida zabwino kwambiri zotchinjiriza magetsi, zomwe zimawapangitsa kukhala chisankho chabwino pamagetsi ndi zamagetsi.Ma polima awa atha kugwiritsidwa ntchito popanga ma insulators, zida zamagetsi, ndi ma board osindikizidwa, pomwe ma conductivity amagetsi amayenera kuchepetsedwa.

BDFA imadziwikanso chifukwa cha kuthekera kwake kukulitsa mphamvu zamakina komanso kusasunthika kwa ma polima.Pophatikizira BDFA mu matrices a polima, zida zomwe zimatuluka zimawonetsa kulimba kwamphamvu, kukana kukhudzidwa, komanso kukhazikika kwa mawonekedwe.Izi zimawapangitsa kukhala oyenera kugwiritsidwa ntchito m'mafakitale omanga, oyendetsa magalimoto, komanso ogulitsa katundu.

Kuphatikiza pakugwiritsa ntchito ma polima ochita bwino kwambiri, BDFA imapeza zothandiza popanga mankhwala apadera, utoto, ndi utoto.Mapangidwe ake apadera a mamolekyu amapereka mwayi wosintha mwamakonda, kulola ofufuza ndi opanga kupanga zida zatsopano zokhala ndi zofananira.
