Nā huahana kemika ʻē aʻe
Ma waho aʻe o ka lula nui, hoʻopili i nā mea hoʻohui hoʻololi, ua hoʻonui ikaika ka ʻoihana i kahi ākea ākea, i mea e hoʻonui ai i ka mahele huahana no nā mea hoʻohana hou aku.
Hiki i ka ʻoihana ke hāʻawi i nā huahana sieve molekiola, 6FXY
(2,2-Bis (3,4-dimethylphenyl) hexafluoropropane) a me 6FDA (4,4 "- (Hexafluoroisopropylidene) diphthalic anhydride).
