Kuphela le nyathelo elifunekayo ukuphucula ifilimu ye-polyimide

Ungaphuculwa njani ukusebenza kwefilimu yepolyimide? Makhe sijonge kunye.

Izinto zefilimu yePolyimide luhlobo lokumelana nobushushu obuphezulu kakhulu, ukumelana nokugqwala, iipropathi zoomatshini, iipropathi zedielectric ezisezantsi, ukumelana nemitha kunye nokuqhubekeka okuphezulu, ke ukusetyenziswa kwayo kubanzi kakhulu kwaye kuyathandwa. Kananjalo inexabiso elikhulu lesicelo kwibala le-aerospace.

Nangona kunjalo, ngenxa yokusingqongileyo okukhethekileyo esikhaleni kunye nobuthathaka bezinto ezikumgangatho ophezulu we-elektroniki, umbane ongatshintshiyo ubangela umonakalo omkhulu kwizixhobo zenqwelomoya kunye neemveliso zombane. I-conductivity yefilimu ye-polyimide ngokwayo iphantsi kakhulu, ethintela ukusetyenziswa kwayo kwi-aerospace kunye neenkalo ezahlukeneyo kwiinkalo ezininzi, ngoko ke ukuguqulwa kwezinto ze-polyimide kuye kwaziswa ngaphambili.

I-Graphene iye yaba ingqwalasela ngokukhawuleza emva kokuba ilungiswe ngo-2004, kwaye i-conductivity yayo egqwesileyo yombane, i-thermal conductivity kunye neempawu zoomatshini zonke zikwinqanaba lokusebenza. Ukongeza igraphene kwizinto eziphathekayo kuya kuphucula ukuqhuba kwayo kunye nokuzinza kwe-thermal.

Olunye uhlengahlengiso lwe-dopant yesinyithi efakwe kwi-polymer composite material kufuneka iqhutywe kwiqondo lokushisa eliphezulu. Ukumelana nokushisa okuphezulu kwe-polyimide kunokuqinisekisa ukubola okuqhelekileyo kunye nokuguqulwa kwe-dopant yensimbi. Iindlela ezininzi zokudibanisa i-polyimide zivumela ukuba iindlela zedoping zahluke. 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 ukuphucula zonke iinkalo zokusebenza kwefilimu ye-polyimide. Ingqwalasela yokuqala xa igraphene idityaniswe kwizinto zepolyimide kukusasazeka. Enyanisweni, i-dispersibility ye-inorganic materials kwi-inorganic/polymer materials ibaluleke kakhulu, kwaye ukufana kokusabalalisa kunokuchaphazela ifilimu edibeneyo elungiselelwe. Ukusebenza.

Eli nqaku laqala ukufunda indlela yokufakwa kwegraphene, ekhangele phambili kwindlela yokuxuba engcono, kunye nokuvavanya kunye nokubonakalisa ukusebenza kwefilimu edibeneyo. Kulindeleke ukuba ukongezwa kwegraphene kuya kuchaphazela i-conductivity kunye neempawu ze-thermal zefilimu ye-polyimide. Kwaye ezinye iipropathi ziqinisekile
