Description
100重量部のポリマー(8)(実施例8で作製)を反応瓶に加え、567重量部のジメチルスルホキシド(DMSO)中に溶解した。次いで、得られたものを消泡して溶液を得た。次いで、その溶液をスピンコーティングによりガラス基板上に塗布し、コーティングを形成した。次いで、そのコーティングを40〜150℃で焼成して、大部分の溶媒を除去した。次いで、そのコーティングを120〜200℃で1〜6時間焼成して残留溶媒を除去し、アニオン交換膜(6)を得た。次に、アニオン交換膜(6)のイオン伝導度および寸法安定性を測定した。その結果が表2に示されている。アニオン交換膜(6)の寸法安定性は、25℃で24時間浸漬した後、Journal of Materials Chemistry A Materials for Energy and Sustainability 3 (23) (2015) 12284-12296にしたがって測定した。
