Indlela yokuthuthukisa ukusebenza kwefilimu ye-polyimide
Ukusebenza kwefilimu ye-polyimide kuyakhathaza kakhulu kumakhasimende nabangane okudingeka bayisebenzise. Uma sifuna ukuhlangabezana nezidingo zethu zangempela zokusetshenziswa, sidinga ukuqonda ngokucacile indlela yokuthuthukisa ukusebenza kwefilimu ye-polyimide. Ngokulandelayo, uchwepheshe Umenzi unikeze isingeniso, ake sisibheke ngokuningiliziwe.
Izinto zefilimu ze-Polyimide zinokumelana nokushisa okuphezulu, ukumelana nokugqwala, izakhiwo zemishini, izakhiwo eziphansi ze-dielectric, ukumelana nemisebe kanye nezakhiwo eziphezulu zokucubungula, ngakho-ke zisetshenziswa kabanzi futhi zanda. Futhi inenani elikhulu lohlelo lokusebenza endaweni ye-aerospace.
Kodwa-ke, ngenxa yemvelo ekhethekile yendawo kanye nobuthakathaka bezingxenye ze-elekthronikhi ezisezingeni eliphezulu, ugesi omile ubangele umonakalo omkhulu emishinini yezindiza kanye nemikhiqizo ye-elekthronikhi. I-conductivity yefilimu ye-polyimide ngokwayo iphansi kakhulu, ekhawulela ukusetshenziswa kwayo ku-aerospace kanye nezinkambu ezihlukahlukene ezicini eziningi. Ngakho-ke, ukwelashwa nokuguqulwa kwezinto ze-polyimide kulethwa phambili.
Kusukela yalungiswa ngo-2004, i-graphene isigxile kakhulu emhlabeni wonke, futhi ukusebenza kwayo okuhle kakhulu kukagesi, ukuqhutshwa kwe-thermal kanye nezakhiwo zemishini kuphakathi kokuhamba phambili. I-graphene ingathuthukisa ukusebenza nokuzinza kokushisa kwento.
Okunye ukuguqulwa kwe-dopant yensimbi efakwe ezintweni eziyinhlanganisela ye-polymer kudinga ukwenziwa ezingeni lokushisa eliphakeme kakhulu. Ukumelana nezinga lokushisa eliphezulu kwe-polyimide kungaqinisekisa ukubola okuvamile nokuguqulwa kwe-dopant yensimbi. Izindlela ezahlukahlukene zokuhlanganisa i-polyimide zingashintsha izindlela zokudotshwa. Ngaphezu kwalokho, ukuncibilika okuphezulu kwe-polyamic acid kuzincibilikisi ze-polar ezinamandla kungasiza izinto ezingaphili ukuthi zifakwe kangcono efilimini ye-polyimide.
Ngakho-ke, kuleli phepha, i-graphene ifakwa ku-polyimide ukuze iguqule ifilimu ye-polyimide, ngaleyo ndlela ithuthukise ngokugcwele ukusebenza kwefilimu ye-polyimide. Uma i-graphene ifakwa ezintweni ze-polyimide, ukuhlakazeka kuwukucatshangelwa kokuqala. Eqinisweni, ukuhlakazwa kwezinto ezingaphili ezintweni ze-inorganic/polymer kubaluleke kakhulu, futhi ukufana kokuhlakazeka kuzothinta ukusebenza kolwelwesi olulungisiwe oluyinhlanganisela. Kuleli phepha, indlela yokufakwa kwe-graphene iqala ukufundwa, futhi indlela engcono yokuxuba ibhekwa. Khona-ke, ukusebenza kwe-membrane eyinhlanganisela kwahlolwa futhi kwaphawulwa. Kulindeleke ukuthi ukungezwa kwe-graphene kuzothuthukisa ukuqhutshwa kwe-conductivity kanye nezakhiwo ezishisayo zefilimu ye-polyimide.
