Preparation and characterization of organic-inorganic composite membranes as proton exchange membrane for fuel cell application |
| 초록 |
Organic-inorganic composite membranes were prepared by the incorporation of inorganic nano-particles into an organic polymer matrix to enhance membrane performances such as thermal stability and mechanical property even at high temperature. In this study, the sulfonated polyimide (SPI)-silica composite membranes were prepared by the introduction of hydrophilic and hydrophobic silica in a nanoscale to improve mechanical, thermal and hydrolytic stability of the sulfonated polyimide membrane. A synthesized oligomer as compatibilizer was further added to induce the homogeneous dispersion of nano-sized silica into polymeric matrix. Eventually, the effect of hydrophilic and hydrophobic silica, and the interaction between sulfonated polymer-solvent for membrane preparation will be discussed in the present study. |
