| titleOfInvention | Anion conducting membrane based on 1,4-diazabicyclo-[2.2.2]-octane cellulose nanofibers cross-linked-quaternary polysulfone and method for preparing the same |
| abstract | The present invention relates to an anionic conductive membrane and a method for producing the same. More particularly, the present invention relates to an anionic conductive membrane in which quaternary polysulfone and 1,4-diazabicyclo [2.2.2] -octane cellulose are cross- ≪ / RTI > The anionic conductive membrane prepared by cross-linking the quaternary polysulfone and 1,4-diazabicyclo- [2.2.2] -octane cellulose according to the present invention can be applied to fuel cell applications, The presence of functionalized cellulose nanofibers induced high hydroxide conductivities of the membrane. In addition, the present invention increases the ion content of the nanophase producing nano-ion channels. The 15 wt% QC-loaded membrane exhibited a high hydroxide conductivity (74.23 mS / cm), 2.7 times that of the PSf / DBB without QC. The composite membranes exhibited good dimensional and alkali stability, mechanical properties and low methanol permeability due to the crosslinking reaction. In addition, other polymer matrices can be used or nano / micro fillers can be introduced to improve membrane stability and ionic conductivity. |
