Poliimide ata tifaga

Polyimide ata tifaga: o se mea maualuga-faatinoga ata tifaga e faavae i luga o le polyimide, lea e faia i le condensation ma le lafoina o le phthalic anhydride (PMDA) ma le diaminodiphenyl ether (DDE) i se solvent malosi polar, sosoo ai ma le imidization; E mafai ona faʻaaogaina e fai ma mea e vavae ese ai maa lithium, e faʻamavae ai eletise lelei ma le le lelei ma puipuia ai le puʻupuʻu.
