Abstract
Description
単分散粒子の規則的集積構造を用いた構造色発現系では、可視光の波長と同じ400nm〜800nm程度の直径の粒子の揃った単分散粒子特に球状粒子が構造の構成単位となる。したがって、着色の波長を制御するためには球状粒子の粒子径を変える必要がある。そのためには、球状粒子の合成の段階からやり直す必要がある。
構造色を発現させるためには、粒子を高度な規則性のある状態で配列させる必要がある。そのためには海面潮力などを利用して非常にゆっくりと粒子を集積させるなど時間をかけて集積構造を形成させる必要がある。また、集積構造の状態により発色が影響を受けるという問題がある。
まず、チタンテトライソプロポキシド(TIP)0.01molと、エチレングリコール(EG)50mLを混合し、更にD−グルコン酸水溶液50mLを加え、TIP−EG+グルコン酸複合体溶液を調整した。なおD−グルコン酸水溶液の濃度は0〜1M(0M、0.05M、0.1M、0.2M、0.5M、1M)に調整し、合計6種のTIP−EG+グルコン酸複合体溶液を調整した。
次に、D−グルコン酸水溶液の濃度を1Mとした粉体に水を加えてゾルとし、水を乾燥させた後、シート状になった乾燥体(グルコン酸複合化層状チタン酸シート状乾燥体)を得た(厚さ0.3mm)。
ここで、グルコン酸複合化層状チタン酸シート状乾燥体の繰り返し特性について確認を行った。具体的には、グルコン酸複合化層状チタン酸シート状乾燥体に水100mlを添加し、完全にグルコン酸複合化層状チタン酸シート状乾燥体が分散するまで静置して分散ゾルとし、UV−Vis透過率スペクトルを測定した後、再び乾燥させてグルコン酸複合化層状チタン酸シート状乾燥体とする工程を複数回繰り返した。このゾル化、乾燥の繰り返しにおけるUV−Vis透過率スペクトルを図10に示しておく。また本図中において、10回目の分散ゾル及びその乾燥体の写真図も示しておく。
ここで、上記方法と同様の方法で作製したグルコン酸複合化層状チタン酸シート状乾燥体に対し、乾燥させた状態又は膨潤させた状態における構造の確認を行った。具体的には、グルコン酸複合化層状チタン酸シート状乾燥体の質量を1とした場合における水の質量比を0〜15に調整したもの(ゲル)を液体窒素で凍結乾燥し、そのSEM像を得た。この結果を図11に示す。
またここで、色の制御について確認を行った。具体的には、グルコン酸複合化層状チタン酸シート状乾燥体に上記用いた水を加えたゾルに、さらにグリセリンを加える量を変化させてその色の制御変化を確認した。まず、図12に、このグルコン酸複合化層状チタン酸のゾルの写真図を示しておく。なおここでは、グルコン酸複合化層状チタン酸ゾルの質量とグリセリン質量の割合を1/10、1/13、1/17、1/20とした場合の例について示しておく。1/20の状態ではゾルは青みがかった色である一方、徐々に変化し、1/13では赤みがかった色に変化し、1/10程度では無色に近くなった。これは板状構造体間の距離が徐々に変化することにより生じた構造色の変化であると考えられる。
