4,4′-(hexafluoroisopropylidene)diphthalicanhydride CAS:1107-00-2

I-anhydride ye-4,4'-(Hexafluoroisopropylidene)diphthalic isetshenziswa kakhulu ekuhlanganisweni kwama-polymer asebenza kahle kakhulu nezinto ezikhethekile ngenxa yezakhiwo zayo zamakhemikhali ezihlukile. Kumakhemikhali we-polymer, isebenza njengesisekelo esibalulekile sokukhiqiza ama-polyimide, aziwa ngokuqina kwawo okushisayo okumangalisayo, amandla omshini, kanye nokumelana namakhemikhali. Lawa ma-polyimide asetshenziswa kabanzi embonini yezindiza, ye-elekthronikhi, kanye neyezimoto zokukhiqiza izingxenye ezidinga ukusebenza okuphezulu ngaphansi kwezimo zokusebenza ezinzima. Ngaphezu kwalokho, le nhlanganisela isetshenziswa ekuthuthukisweni kwezimbozo ezikhethekile namafilimu anezakhiwo ezivelele zokumelana nokushisa kanye nezithiyo. Lezi zimbozo zithola ukusetshenziswa ezingqimbeni zokuvikela zamadivayisi kagesi, izimbozo ezingagqwali zemishini yezimboni, kanye nezinto zokuvimbela ukushisa okuphezulu. Ngaphezu kwalokho, i-anhydride ye-diphthalic engu-4,4'-(Hexafluoroisopropylidene)diphthalic inegalelo ekudalweni kwezinto ezihlanganisiwe ezithuthukisiwe ezisetshenziswa ezinhlotsheni zezindiza kanye nezokuvikela. Ukufakwa kwayo kuma-matrices ahlanganisiwe kuthuthukisa ukuzinza kwawo kokushisa, izakhiwo ezivimbela ilangabi, kanye nokuqina okuphelele, okwenza zifanelekele izidingo zesakhiwo nezokusebenza ezidingekayo ezindizeni, ezindiza-mkhathi, kanye nemishini yezempi. Ngaphezu kwalokho, le nhlanganisela idlala indima ebalulekile ekwakhiweni kwezinamathiselo ezikhethekile kanye nezivalo ezinikeza amandla amahle kakhulu okubopha kanye nokumelana namazinga okushisa aphezulu, amakhemikhali, kanye nokucindezeleka kwemvelo. Lezi zinamathiselo zithola usizo ekuhlanganiseni izingxenye ezibalulekile embonini ye-elekthronikhi, yezimoto, kanye neyamadivayisi ezokwelapha lapho ukuthembeka nokusebenza kubaluleke kakhulu. Ngamafuphi, i-anhydride ye-diphthalic engu-4,4'-(Hexafluoroisopropylidene) isebenza njengesisekelo sokwakha ama-polymer asebenza kahle, izembozo ezikhethekile, izinto ezihlanganisiwe, kanye nezinamathiselo ezinokuzinza kokushisa okumangalisayo, amandla omshini, kanye nokumelana namakhemikhali. Ukusetshenziswa kwayo okuguquguqukayo kunegalelo ekuthuthukisweni kwemikhakha ehlukahlukene yezimboni, okuvumela ukuthuthukiswa kwezinto ezintsha ezenzelwe izidingo zobuchwepheshe nezokusebenza ezidingakalayo.
