Proton-conducting polymer membrane comprised of cross linked Poly 2-hydroxyethyl methacrylate with Nafion® for fuel cell application |
| 초록 |
In order to increase water retention and proton-conducting property of Nafion®, we prepared a cross-linked copolymer of Poly 2-hydroxyethyl methacrylate (HEMA) and Nafion®. Poly(2-hydroxyethyl methacrylate) (HEMA) was chosen as a copolymer because it produces a water-insoluble but water-swellable polymer. Although, it is hydrophobic, it water-swellable character means water will not be excluded from the copolymer. Introduction of Poly HEMA into Nafion® prevents polymer solubility, provide structural stability and rigidity that should in turn reduce methanol permeability. Moreover, convenient permeability of poly(HEMA) to cations make itself a good candidate for hydrocarbon proton conducting polymer tuned with Nafion® |
