3,3′,4,4′-Biphenyltetracarboxylic dianhydride CAS:2420-87-3

I-dianhydride engu-3,3', 4,4'-Biphenyltetracarboxylic iyisakhiwo esibalulekile ekwakhiweni kwama-polymer amelana nokushisa okuphezulu, njenge-polyimides kanye ne-poly (ether ether ketone) (PEEK). Lawa ma-polymer anezicelo ezindizayo, ezimotweni, kuma-elekthronikhi, nakwezinye izimboni ngenxa yokuqina kwawo okushisa okumangalisayo, amandla omshini, kanye nokumelana namakhemikhali. Le nhlanganisela isetshenziswa futhi njenge-ejenti yokuxhumanisa ekukhiqizweni kwama-resin e-epoxy, okuthuthukisa izakhiwo zawo zokushisa nezomshini. Ngaphezu kwalokho, isetshenziswa ekwenziweni kwezinto ze-elekthronikhi, njenge-polymers ye-liquid crystal kanye nama-polymers e-semiconducting, ngenxa yamandla ayo okunikeza ukuzinza kokushisa okuphezulu kanye nezakhiwo zikagesi emikhiqizweni yokugcina. Ngaphezu kwalokho, i-dianhydride engu-3,3', 4,4'-Biphenyltetracarboxylic isetshenziswa ocwaningweni lwezemfundo nolwezimboni lokufunda ukusabela kwezinto eziphilayo kanye nokuthuthukisa izinto ezintsha ezinezakhiwo ezilungiselelwe. Isakhiwo sayo samakhemikhali esiyingqayizivele kanye nokusabela kwayo kwenza kube yingxenye ebalulekile ekuthuthukisweni kwama-polymers athuthukile nezinto ezinezinhlelo zokusebenza ezahlukahlukene. Ngamafuphi, i-3,3', 4,4'-Biphenyltetracarboxylic dianhydride iyinhlanganisela enezicelo ekukhiqizweni kwama-polymer asebenza kahle, ama-agent axhumanisayo, izinto zikagesi, kanye nocwaningo lwezemfundo. Izakhiwo zayo eziyingqayizivele zamakhemikhali ziyenza ibe yingxenye ebalulekile ezinqubweni ezahlukahlukene zezimboni kanye nemizamo yocwaningo lwesayensi.
