A proton conductive silicate-nanoencapsulated polyimide nonwoven as a novel porous substrate for a reinforced sulfonated poly(arylene ether sulfone) composite membrane |
| 초록 |
A novel reinforcing porous substrate that features unprecedented capability of offering proton conductivity is demonstrated for potential use in a reinforced composite proton exchange membrane. The unusual porous substrate (hereinafter, referred to as ‘‘sPI substrate’’) is composed of 3-trihydroxysilyl propane-1-sulfonic acid (THSPSA)-based silicate nanoencapsulating layers (shell) and electrospun polyimide (PI) nonwoven fibers (core). The core-shell structured sPI substrate maintains a highly porous structure, which plays a crucial role in providing effective proton-conducting channels after the impregnation of a polymer electrolyte (herein, sulfonated poly(arylene ether sulfone) (SPAES)). Notably, owing to the assistance of the proton-conductive sPI substrate, the sPI substrate-reinforced SPAES composite membrane presents higher proton conductivity than a PI nonwoven-reinforced SPAES composite membrane at various relative humidity (RH) conditions. |
