| Abstract | This study presents the effects of sulfonate incorporation and structural isomerism of soluble sulfonated polyimides (SPIs) for potential membrane applications. The fluorinated dianhydride (6FDA) and three commercially sulfonated diamines, 2,4,6-trimethyl-3,5-diaminobenzenesulfonic acid (tDSA), 2,5-diaminobenzenesulfonic acid (pDSA), and 2,4-diaminobenzenesulfonic acid (mDSA), were used to synthesize SPIs in a one-step polycondensation. The SPIs are soluble in common organic solvents and have good mechanical properties as represented by tensile strength of 88.4-115.8 MPa and elongation at break of 10.3-15.2%. The resulting SPI membranes exhibit low dielectric constants (similar to 2.61) and linear thermal expansion coefficients (CTE) ranging from 54.6 to 71.7 ppm/K. These SPI membranes have fractional free volume (FFV) of 0.119-0.148. The sulfonation incorporation induced closer inter-chain packing, smaller FFV, larger CTE, higher average refractive indices (n(av)), better transparency and higher ideal selectivities for almost all gas pairs for their membranes. The para-linked TEA-pSPI membrane exhibited a larger inter-chain d-spacing, larger FFV, larger CTE, smaller nav and slightly higher permeability coefficients than the corresponding meta-linked TEA-mSPI membrane. This study guides molecular architecture for improving particular membrane performance by introducing sulfonation groups as well as adjusting either para- or meta-linkages into polymeric main chains. |
