Heerka Khatarta CARUUR-DHAAFO AH
2,2'-Bis (trifluoromethyl) benzidine (TFMB; TFDB) (CAS: 341-58-2) waxaa loo isticmaalaa soo saarida xoog sare oo dabacsan walxo polyimide hufan.Dhexdhexaadiye crystal dareere ah.
2,2'-Bis (trifluoromethyl) benzidine waa monomer muhiim u ah isku dhafka polyimide.Polyimide-ku waxa uu la sameeyay TFMB sida monomer-ku u soo bandhigo kooxaha fluorine.Curiyaha fluorine waxa uu leeyahay raadiyaha atomiga yar iyo electronegativity sare, taas oo ka dhigaysa polyimide haysashada sifooyin dhamaystiran oo heer sare ah iyada oo la siinayo siyaalo badan oo gaar ah, sida xasiloonida kulaylka, firfircoonida kiimikaad, sifooyin farsamo oo aad u fiican, iwm.
2,2'-Bis (trifluoromethyl) benzidine waxaa inta badan loo isticmaalaa beeraha microelectronics iyo optoelectronics si loogu diyaariyo dielectric joogto ah aadka u hooseeya, tamar aad u hooseeya oo dusha sare ah, xoog farsamo oo aad u sarreeya, caabbinta xirashada aadka u sarreeya, midab lahayn iyo qalabka PI, iyo waa monomer-ka ugu caansan ee ka mid ah dhammaan monomer-yada PI diamine-ka ku jira fluorine.
