Na filimi ea polyimide e hanana le mocheso o phahameng le mocheso o tlase?

Filimi ea Polyimide ke mofuta o mocha oa filimi ea polymer e hanyetsanang le mocheso o phahameng, e entsoeng ka pyromellitic dianhydride (PMDA) le diaminodiphenyl ether (ODA) ka har’a mokelikeli o matla haholo oa dimethylacetamide (DMAC) Ho etsoa condensation e bohareng le mathe, ebe ho etsoa imidization. tsoa. Ke thepa e sireletsang filimi e tšesaane ka ho fetisisa lefatšeng ‘me e na le matla a babatsehang.
