Description
1.導電材と結着材の配合比率の検討
(塗料および試料の作製)
結着材としてフッ化ビニリデン−六フッ化プロピレン(VDF−10重量%HFP)共重合体樹脂を用い、これを表1に示す配合でN−メチルピロリドン(NMP)に溶解した溶液に、平均粒子径4μmの天然黒鉛粉末(黒鉛)とファーネスブラック(カーボンブラック)を8:2で投入し、分散処理を行った。その後、溶媒のNMPを適当量加えることにより、最終的な固形分・粘度を調整し、試料番号11〜15の燃料電池セパレーター用の導電塗料を作製した。
上記の評価用試料の塗膜について、体積抵抗、面抵抗および密着性を次に示す方法により評価した。体積抵抗は、ガラス板上に塗料を塗布した試験片の塗膜に測定端子を押し付け、4探針4端子法(ダイアインスツルメンツ社製のロレスターAP)により塗膜面方向の体積抵抗を測定した。面抵抗は、炭素鋼板上に塗料を塗布した試験片を銀板により挟み込み、4端子法(HIOKI社製の3560mΩHiTESTER)を用いて、炭素鋼込みの塗膜面に垂直な方向の面抵抗を測定した。
次に、結着材としてフッ化ビニリデン−六フッ化プロピレン(VDF−5,15,30重量%HFP)共重合体樹脂、および/または、ポリフッ化ビニリデン(PVDF)樹脂を表2に示す配合で用い、上記の導電材と結着材の配合比率の検討における塗料および試料の作製に記載の方法と同様に、試料番号21〜26の燃料電池セパレーター用の導電塗料を作製し、同様の評価を行って樹脂の種類の影響について検討した。塗料組成および得られた塗膜の評価結果は表2に示した。
次に、表3に示す配合に有機溶剤量を変更した以外は、上記の導電材と結着材の配合比率の検討における塗料および試料の作製に記載の方法と同様に、試料番号31〜34の燃料電池セパレーター用の導電塗料を作製し、同様の評価を行って塗料の固形分および粘度が及ぼす影響について検討を行った。塗料組成および得られた塗膜の評価結果は表3に示した。
次に、導電材の黒鉛に添加するカーボンブラックの添加量を、表4に示す配合に変更した以外は、上記の導電材と結着材の配合比率の検討における塗料および試料の作製に記載の方法と同様に、試料番号41〜45の燃料電池セパレーター用の導電塗料を作製し、同様の評価を行ってカーボンブラックの添加量の及ぼす影響について検討を行った。塗料組成および得られた塗膜の評価結果は表4に示した。
