4,4′-Oxydiphthalic anhydride CAS:1823-59-2

Anhydride ea 4,4'-Oxydiphthalic e na le mefuta e fapaneng ea lits'ebetso ho pholletsa le liindasteri tse fapaneng, haholo-holo ka lebaka la katleho ea eona e le monomer tlhahisong ea li-resin tsa polyimide le li-polymer tse ling tse sebetsang hantle. Li-polymer tsena li tsejoa ka botsitso ba tsona bo botle ba mocheso, khanyetso ea lik'hemik'hale le matla a mechini, e leng se etsang hore li lokele lits'ebetso tse hlokang tlhokomelo makaleng a kang lisebelisoa tsa elektroniki, lifofane le tlhahiso ea likoloi. Indastering ea lisebelisoa tsa elektroniki, anhydride ea 4,4'-oxydiphthalic e sebelisoa ho etsa lisebelisoa tse sireletsang mocheso bakeng sa liboto tsa potoloho le likarolo tse ling. Ho tsitsa ha mocheso oa li-polymer tse tsoang ho anhydride ena ho li lumella ho sebetsa ka mokhoa o tšepahalang tlas'a maemo a mocheso o phahameng, e leng sa bohlokoa bakeng sa lisebelisoa tsa elektroniki tsa sejoale-joale. Ho feta moo, e bapala karolo ea bohlokoa tlhahisong ea liphahlo le likhomaretsi. Ho kenyelletsoa ha eona mefuteng ho ntlafatsa thepa ea ho khomarela le ho tšoarella, ho etsa hore e be e loketseng liphahlo tse sireletsang lits'ebetsong tsa kaho le tsa indasteri. Liphahlo tsena li fana ka khanyetso khahlanong le mafome, lik'hemik'hale le maemo a thata a tikoloho. Ho phaella moo, anhydride ea 4,4'-oxydiphthalic e sebelisoa ho etseng lik'hemik'hale tse ikhethang le tse mahareng. Karabelo ea eona e ikhethang e nolofalletsa ho kopanngoa ha limolek'hule tse fapaneng tse rarahaneng tse ntseng li sebetsoa ka ho eketsehileng hore e be meriana, lik'hemik'hale tsa temo le lik'hemik'hale tse ling tse ntle. Ka kakaretso, litšobotsi tse fapaneng tsa anhydride ea 4,4'-oxydiphthalic li e etsa hore e be motheo oa bohlokoa oa thepa e tsoetseng pele le lits'ebetsong tsa indasteri, e leng se tlatsetsang haholo litharollong tse ncha theknolojing le tlhahisong.
