Abstract
Description
金、銀、銅などに代表される金属色は、古代から高級感の象徴として捉えられており、現在でも金属光沢色塗料は、自動車や装飾品などを始めとするあらゆるものに使用されている。既存の金属光沢色塗料はアルミニウムや亜鉛などの金属フレークを分散させることにより光沢感を発現している。しかし分散安定性が極めて低く、色や光沢のむらが生じやすいという課題があるため、近年は非金属材料を用いて金属光沢色を発現させる試みがなされている。
原料モノマーである3MeOT(濃度0.1M、和光純薬社製 純度98%以上)のアセトニトリル(関東化学社製、純度99.7%以上)溶液10mLに、酸化剤であるテトラフルオロほう酸銅(II)(濃度0.2 M、和光純薬社製 純度98%以上)のアセトニトリル溶液(10mL)を加え、窒素雰囲気下で2時間重合を行った。重合後に、ろ過、洗浄、真空乾燥を経て生成物であるBF4 −ドープされた3MeOT重合体を得た。次に、得られた3MeOT重合体粉末を1重量パーセントの濃度でニトロメタン(東京化成工業社製 純度98%以上)に溶解し、塗布液を作製した。そしてキャスト法によりITO(ジオマテック社製、シート抵抗値10Ω/□)基板上に塗布し、自然乾燥させることで製膜を行い、3MeOT重合体膜電極を得た。
図4に3MeOT重合体膜電極のサイクリックボルタンモグラム、図5に同時に測定した600nmにおける反射率と電位の関係を示す。図4のサイクリックボルタンモグラムを見ると、−0.3V近傍の還元波はBF4 −の脱ドーピング反応に対応する還元電流であり、0.3 V近傍の酸化波はBF4 −のドーピング反応に対応する酸化電流である。+0.2Vから負方向に電位を掃引すると、膜の色調は金色調から緑色光沢色に変化し、正方向の掃引では、酸化開始電位の0V近傍から膜の色調は緑色光沢色から金色調に変化した。その色変化の様子は、600nmにおける反射率の電位依存性(図5)からも確認された。なお、図6には、−0.5V(a, 緑色光沢色)および+0.5V(b,金色調)で電位を固定して得られた膜の写真を示す。図6の上の図が−0.5Vで観察された緑色光沢色に発色した膜の写真であり、図6の下の図が0.5Vで観察された金色調に発色した膜の写真である。図6のスケールバーの長さは、0.2mmである。
アニオン(BF4 -)ドープ3−メトキシチオフェン重合体を合成し、それを透明導電性基板上に塗布してエレクトロクロミック電極を作製した。得られた3MeOT重合体膜電極は、電気化学的酸化還元反応により、金色調と光沢を持つ緑色との間で可逆的な光沢色変化を起こすことが判明した。これは自然の見えで光沢色が変化する初のエレクトロクロミズムである。
