| 제목 | Anion-Exchange Membrane Manufacturing by Radiation Grafting for Ionic Polymer Metal Composites (IPMCs) |
| 초록 | Ionic Polymer Metal Composites (IPMCs) are composed of metal electrode and electrolyte. The metal electrode is used platinum and gold. Electrolyte is commonly used cation exchange membrane such as Nafion. However, anion-exchange membrane can be used as electrolyte for IPMCs, too.1 The actuation mechanism of anion-exchange membrane IPMCs is similar to that of normal IPMCs, but bending direction is opposite. Because the mobile ion of anion-exchange membrane IPMCs is anion, while that of normal IPMCs is cation. If anion-exchange membrane IPMCs and normal IPMCs are assembled, the IPMCs can do various modes actuation. Radiation grafting method has frequently been used to manufacture ion-exchange membranes. Typically, radiation grafting method involves three steps. First a fluoropolymer is irradiated with γ-ray. Second the irradiated polymer is grafted with monomer. Third the grafted polymer is functionalized. The method has various advantages. Manufacturing process is convenient, the degree of grafting can be controlled, and production cost is low. In this study, anion-exchange membrane was prepared by radiation grafting. Poly(vinylidene fluoride-co-hexafluoropropylene) (P(VDF-co-HFP)) used as initial matrix. 4-vinyl pyridine was used as monomer. Hydrochloride and methyl iodide were used as funtionalization agents.2 The degree of grafting (DOG), the ion-exchange capacity (IEC) and the water uptake of the anion-exchange membrane were measured. IPMCs made of anion-exchange membrane were tested with laser displacement meter. Fig. 1. A scheme for preparation of anion exchange membrane by radiation grafting. Reference 1. K. Asaka, N.
