The transport properties of He, H P , COP, 02, NP, and CH, gases in solvent cast, HCl doped, and undoped polyaniline (PANi) membranes were determined. Measurements were carried out a t 40 psi pressure from 19ยฐC to 60ยฐC. An excellent correlation was found between the diffusion coefficients and the mo
Hydrogen, oxygen and carbon dioxide transport properties are studied at various hydration rates for a large series of sulfonated copolyimides synthesized with a naphthalenic dianhydride, a sulfonated diamine and various non-sulfonated diamines. For all copolymers, the gas permeability coefficient de
Gas transport properties of homo-and copolyimides prepared from 3,3,4,4-and 2,2,3,3-thiaphthalic dianhydride ( p-TDPA and m-TDPA, respectively) with 4,4-oxydianiline (ODA) were investigated. The fractional free volume of m-TDPA-ODA is larger than that of p-TDPA-ODA, and the chain segmental mobility
