Ingabe ifilimu ye-polyimide imelana kancane nezinga lokushisa eliphezulu nezinga lokushisa eliphansi?

Ifilimu ye-Polyimide iwuhlobo olusha lwefilimu ye-organic polymer ekwazi ukumelana nokushisa okuphezulu, elakhiwe i-pyromellitic dianhydride (PMDA) kanye ne-diaminodiphenyl ether (ODA) ku-solvent eqine kakhulu i-dimethylacetamide (DMAC) Ukufingqa nokuphuma amathe okumaphakathi, bese kwenziwa imidization. ngaphandle. Iyinto esebenza kakhulu yokuvikela ifilimu emincane emhlabeni futhi inamandla amakhulu. Umsebenzi kagesi, ukuzinza kwamakhemikhali nokumelana nemisebe ephezulu, izinga lokushisa eliphezulu nokumelana nokushisa okuphansi (-269~ +400~C).
