Description
項1. 基板(D)の少なくとも一部又は全体を少なくとも一軸方向に延伸(F)された状態の基板(D)上に表層(E)を形成し、基板(D)の延伸状態を解除したときに発生する圧縮歪みに基づき形成された凹凸構造を有し、前記凹凸構造のアスペクト比が0.2〜1.0の範囲にある、微細凹凸構造材料。
項2. 基板(D)の弾性率(Ea)と表層(E)の弾性率(Eb)が、Ea≦Ebの関係を有する、項1に記載の材料。
項3. 前記構造が、50nm以上500μm以下の周期を有する、項1〜2のいずれかに記載の材料。
項4. 基板(D)の材料の延伸率(延伸時の延伸方向の長さ/非延伸時の延伸方向の長さ)が1.2〜10である、項1〜3のいずれかに記載の材料。
項5. 以下の工程1〜工程3:
工程1:基板(D)の少なくとも一部又は全体を少なくとも一軸方向に延伸(F)する工程、
工程2:延伸された状態の基板(D)上に表層(E)を形成する工程、
工程3:基板(D)の延伸状態を解除して、凹凸構造を形成する工程、
を含むことを特徴とする、アスペクト比が0.2〜1.0の範囲にある微細凹凸構造を有する項1〜4のいずれかに記載の材料の製造方法。
項6. 工程1における基板(D)の材料の延伸率(延伸時の延伸方向の長さ/非延伸時の延伸方向の長さ)が1.2〜10である、項5に記載の方法。
基板(D)と表層(E)を合わせた部材は透明又は半透明の材料であるのが好ましく、可視・赤外光の透過率は30%以上、好ましくは70%以上、より好ましくは90%以上である。
表層(E)の厚みとしては、1〜50000nm程度が挙げられる。
実施例1
(1)0.4程度の高アスペクト比かつサブミクロンの規則性の高い凹凸構造を得る方法
厚さ1mm程度の20×40mm程度のPDMSゴムを成形し、それを両側で固定し延伸機で150%程度延伸した状態で、スパッタ蒸着により金(白金でも可)を約1nm蒸着し、その後、延伸状態を解放し、100%の状態に戻すことで目的の凹凸構造(図1)を得る。ここで表層と基板の有効弾性率はそれぞれ、約200GPa、20MPaである。
(2)アスペクト比を再現性よく制御する方法
前項同様に、厚さ1mm程度の20×40mm程度のPDMSゴムを成形し、それを両側で固定し延伸機でX倍に延伸した状態で、スパッタ蒸着により金(白金でも可)を数nm蒸着し、その後、延伸状態を解放し、100%の状態に戻すことで目的の凹凸構造を得るが、そのアスペクト比と延伸率Xとの関係(図2)を得た。データは空間波長200nm-1000nmでの結果を含む。
Claims (1)
- 基板(D)を両側で固定し、少なくとも一部又は全体を一軸方向に延伸(F)し、延伸された状態の基板(D)上に表層(E)を形成し、該固定を解除することにより基板(D)の延伸状態を解除することによって得られる微細凹凸構造材料であって、当該基板(D)の延伸状態を解除したときに発生する圧縮歪みに基づき形成された周期的凹凸構造を有し、前記凹凸構造のアスペクト比が0.2〜1.0の範囲にあり、基板(D)の弾性率(Ea)と表層(E)の弾性率(Eb)が、Ea≦Ebの関係を有し、前記微細凹凸構造が、50nm以上500μm以下の周期を有し、基板(D)の材料の延伸率(延伸時の延伸方向の長さ/非延伸時の延伸方向の長さ)が1.2〜10である、微細凹凸構造材料。
