The preferable preparation method of SPEEK/BPO4 composite membranes for enhancement of proton conductivity via an in-situ sol-gel process |
| 초록 |
Sulfonated poly(ether ether ketone) (SPEEK)/boron phosphate (BPO4) composite membranes were prepared via an in-situ sol-gel process. Several variables such as reaction time, reaction temperature and solution-cast form of SPEEK were investigated to explain the relationship between the size of BPO4 and the proton conductivity. The size of BPO4 and proton conductivity were not dependent on reaction time and reaction temperature in the in-situ sol-gel process, while the solution-cast form of the membranes strongly influenced the size of BPO4. The composite membrane using H+-form SPEEK included the bigger size of BPO4 in the matrix. Moreover, water uptake of the composite membrane using H+-form SPEEK was higher than that of the composite membrane using Na+-form SPEEK due to the bigger size of BPO4, and the proton conductivity was enhanced in the composite membranes using H+-form SPEEK. |
