Abstract:

An amine-terminated hyperbranched polyimide(Am-HBPI) was introduced into a sulfonated flurenyl-containing polyetheretherketoneketone(SFPEEKK) matrix to form “acid-base” blends for proton conductive membranes. The uniform and flexible blend membranes were obtained by a solution casting procedure with a unique phase-separation microstructure. Both TEM and SEM images clearly showed that the nano-sized Am-HBPI particles were well dispersed in SFPEEKK continuous phase. In comparison with the pristine SFPEEKK membrane, the blend membranes containing Am-HBPI “performance-enhancing component” exhibited improved dimensional stability and better mechanical properties. Meanwhile, their proton conductivity could be 0.12—0.16 S/cm at 100 ℃.
