Indlela yokuphucula ukusebenza kwefilimu ye-polyimide

Ukusebenza kwefilimu ye-polyimide kubaxhalabisa kakhulu abathengi kunye nabahlobo abafuna ukuyisebenzisa. Ukuba sifuna ukuhlangabezana neemfuno zethu zokusetyenziswa kwangempela, kufuneka siqonde ngokucacileyo indlela yokuphucula ukusebenza kwefilimu ye-polyimide. Oku kulandelayo, ubuchwephesha Umenzi wanika intshayelelo, makhe sijonge kuyo ngokweenkcukacha.

Izinto zefilimu yePolyimide zinokumelana nobushushu obuphezulu, ukuxhathisa ukubola, iipropathi zoomatshini, iipropathi eziphantsi ze-dielectric, ukumelana nemitha kunye neempawu eziphezulu zokusetyenzwa, ngoko ke zisetyenziswa ngokubanzi kwaye zithandwa. Kananjalo inexabiso elikhulu lesicelo kwibala le-aerospace.

Nangona kunjalo, ngenxa yokusingqongileyo okukhethekileyo kwendawo kunye nobuthathaka bezinto ze-elektroniki eziphezulu, umbane ongatshintshiyo uye wabangela umonakalo omkhulu kwizixhobo ze-aviation kunye neemveliso zombane. I-conductivity yefilimu ye-polyimide ngokwayo iphantsi kakhulu, ethintela ukusetyenziswa kwayo kwi-aerospace kunye neenkalo ezahlukeneyo kwiinkalo ezininzi. Ngoko ke, unyango kunye nokuguqulwa kwezinto ze-polyimide ziye zaziswa phambili.

Ukusukela ekulungisweni kwayo ngo-2004, igraphene iye yaba ingqwalasela kwihlabathi liphela, kwaye ukuhanjiswa kwayo kombane okugqwesileyo, ukuhanjiswa kwe-thermal kunye neempawu zoomatshini ziphakathi kwezona zibalaseleyo. I-graphene inokuphucula i-conductivity kunye nokuzinza kwe-thermal yezinto.

Olunye uhlengahlengiso lwe-dopant yesinyithi efakwe kwi-polymer composite material kufuneka luqhutywe kwiqondo lokushisa eliphezulu. Ukumelana nokushisa okuphezulu kwe-polyimide kunokuqinisekisa ukubola okuqhelekileyo kunye nokuguqulwa kwe-dopant yensimbi. Iindlela ezahlukeneyo zokudityaniswa kwepolyimide zinokwahluka iindlela zokusebenzisa idoping. Ukongeza, ukunyibilika okuphezulu kwe-polyamic acid kwizinyibilikisi ezinamandla zepolar kunokunceda izinto ezingaphiliyo ukuba zifakwe ngcono kwifilimu ye-polyimide.

Ngoko ke, kweli phepha, i-graphene ifakwe kwi-polyimide ukuguqula ifilimu ye-polyimide, ngaloo ndlela iphucula ngokubanzi ukusebenza kwefilimu ye-polyimide. Xa igraphene idityaniswe kwimathiriyeli yepolyimide, ukusasazwa luqwalaselo lokuqala. Enyanisweni, ukusasazwa kwezinto ezingabonakaliyo kwi-inorganic / polymer materials kubaluleke kakhulu, kwaye ukufana kwe-dispersion kuya kuchaphazela ukusebenza kwe-membrane edibeneyo elungiselelwe. Kulo phepha, indlela yokufakwa kwegraphene iqala ukufundwa, kwaye indlela yokuxuba engcono ilindelwe. Emva koko, ukusebenza kwe-membrane edibeneyo kuhlolwe kwaye kubonakaliswe. Kulindeleke ukuba ukongezwa kwegraphene kuya kuphucula i-conductivity kunye neempawu ze-thermal zefilimu ye-polyimide.
