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

3,3',4,4'-Biphenyltetracarboxylic dianhydride waa baloog muhiim ah oo lagu dhiso polymers-ka u adkaysta heerkulka sare, sida polyimides iyo poly(ether ether ketone) (PEEK). Polymers-kani waxay leeyihiin codsiyo hawada sare, baabuurta, elektarooniga, iyo warshadaha kale sababtoo ah xasilloonidooda kulaylka ee gaarka ah, xoogga farsamada, iyo iska caabbinta kiimikada. Isku-darka ayaa sidoo kale loo isticmaalaa sidii wakiil isku-xidha soo saarista resins-ka epoxy, taasoo kor u qaadaysa sifooyinkooda kulaylka iyo farsamada. Intaa waxaa dheer, waxaa loo isticmaalaa soo saarista agabka elektaroonigga ah, sida polymers-ka dareeraha ah ee kiristaalka ah iyo polymers-ka semiconducting, sababtoo ah awooddeeda ay ku siin karto xasillooni heerkul sare leh iyo sifooyin koronto alaabada kama dambaysta ah. Intaa waxaa dheer, 3,3',4,4'-Biphenyltetracarboxylic dianhydride waxaa loo isticmaalaa cilmi-baarista tacliinta iyo warshadaha si loo barto falcelinta dabiiciga ah iyo horumarinta agab cusub oo leh sifooyin gaar ah. Qaab-dhismeedkeeda kiimikada ee gaarka ah iyo fal-celinta ayaa ka dhigaya qayb qiimo leh oo ku jirta horumarinta polymers-ka horumarsan iyo agabyada leh codsiyo kala duwan. Marka la soo koobo, 3,3',4,4'-Biphenyltetracarboxylic dianhydride waa isku-dhafan oo leh codsiyo lagu sameeyo soo saarista polymers-ka waxqabadka sare leh, wakiilada isku xidhka, agabka elektaroonigga ah, iyo cilmi-baarista tacliinta. Sifooyinka kiimikada ee gaarka ah ayaa ka dhigaya qayb qiimo leh oo ku jirta hababka kala duwan ee warshadaha iyo dadaallada cilmi-baarista sayniska.
