Embodiment approach
[0168] Hereinafter, the embodiments of the present invention will be described in detail so that those skilled in the art of the present invention can easily implement them. However, the present invention can be implemented in various forms and is not limited to the examples described below.
Embodiment 1-1
[0171] After electrospinning under the state of applying a voltage of 30KV to the polyamic acid / THF spinning solution with a concentration of 12% by weight, a nano-network precursor of polyamic acid is formed, and then it is carried out in an oven at 350°C for 5 hours. Heat treatment was performed to manufacture a polyimide porous support having an average thickness of 15 μm. At this time, the electrospinning was performed at 25° C. with a voltage of 30 kV applied to the nozzle.
[0172] SPEEK (sulfonated polyetheretherketone, sulfonated polyetheretherketone) was dissolved in N-methyl-2-pyrrolidinone (N-methyl-2-pyrrolidinone, NMP) to prepare a 10% by weight ion conductor solution.
[0173] The porous support was immersed in the solution of the ion conductor. Specifically, the immersion process was performed at room temperature for 20 minutes. At this time, a reduced-pressure environment was applied for about 1 hour to remove microbubbles. Thereafter, NMP was removed by dryin...
Embodiment 1-2
[0177] An etching solution was prepared by diluting SPEEK (sulfonated polyetheretherketone, sulfonated polyetheretherketone) as an ion conductor with DMAc as a solvent. At this time, the above-mentioned ion conductor was contained in the above-mentioned etching solution in an amount of 3% by weight relative to the total weight of the above-mentioned etching solution.
[0178] At room temperature, at 0.1ml / ㎝ 2 After spraying the above-produced etching solution on the surface of the ion-exchange membrane produced in the above-mentioned Example 1-1, it was dried in a hot IR oven kept at 80° C. for etching treatment. On the surface of the ion conductor produced above, fine irregularities with a length of 3% of the total thickness of the silica coating layer were formed.
