Description
(1)高い屈折率と低い屈折率の交互の薄層からなる防反射層の積層が設けられた板ガラスであって、該防反射層の積層の最終層が光触媒特性を有するコーティングからなり、該コーティングが少なくとも部分的に結晶質であるアナターゼ形の酸化チタンを含み、結晶質酸化チタンは0.5〜60nmの平均サイズを有する結晶子の形態であり、該コーティングが5〜50nmの厚さを有する、板ガラス、ならびに
(2)高い屈折率と低い屈折率の交互の薄層からなる防反射層の積層が設けられた窓ガラスであって、該防反射層の積層の最終層が光触媒特性を有するコーティングからなり、該コーティングが少なくとも部分的に結晶質であるアナターゼ形の酸化チタンを含み、結晶質酸化チタンは0.5〜60nmの平均サイズを有する結晶子の形態であり、該コーティングが5〜50nmの厚さを有する、窓ガラス、である。
また、特に、アナターゼ形の結晶の場合、基材上で成長するTiO2 結晶の向きは、酸化チタンの触媒挙動に影響を有し、光触媒を顕著に促進する好適な配向(1,1,0)が存在する。
1.チタン前駆体の分解
1)熱分解法の液体熱分解、粉末熱分解、化学蒸着(CVD)として知られる気相中での熱分解など
2)ゾルゲルを用いた技術の浸漬、セルコーティングなど
2.真空技術
反応性又は非反応性の陰極スパッタリングなどが挙げられる。
CF3−(CF2)n−(CH2)m−SiX3
(式中nは0〜12、mは2〜5、Xは加水分解基)のシランを主成分にしたものの層が挙げられる。
1.親水性は、コーティング上に堆積し得る水の完全な濡れを可能にする。水の凝縮現象が生じると、視界を妨げる曇り状の水滴を堆積させず、コーティングの表面上に生成した完全に透明な水の連続的薄膜が存在する。この「曇り防止(anti-condensation) 」作用は、光に曝されたとき、5°未満の水との接触角が測定される場合に特に顕著である。
2.光触媒層で処理していない表面の上を水(特には雨水)が走ると、多数の雨水の滴が表面に付着して残り、蒸発すると、主に無機物に由来する見た目の悪い汚れ跡が残る。実際には、周りの空気に曝された表面は、汚れの層で直ぐに覆われ、水によって濡れるのを制限する。これらの汚れは、その他の汚れ(特に、結晶化の跡などの無機物的痕跡)に加え、ガラスが存在する雰囲気に影響される。光触媒表面の場合、これらの無機物の汚れは、光触媒によっては直接に分解されない。実際には、光触媒活性によってもたらされる親水性により、殆どが除去される。この親水性は、事実として、雨の滴の完全な広がりを生じさせる。したがって、蒸発の跡はもはや存在しない。また、その他の無機物の汚れが表面上に存在すると、水膜によって洗浄されあるいは結晶の場合は再溶解され、このため殆どが除去される。特に雨によって誘引される「無機物汚れ防止」作用が得られる。
3.親水性と相まって、コーティングは、親油性を呈することができ、これにより、水と同様に、極めて局所的な「染み」よりも見えにくい連続的膜の形態で、コーティング上に堆積した有機物の汚れを「濡れ」させることができる。「有機物の汚れ防止」効果は、2つの仕方の作用によって得られ、即ち、コーティング上に堆積すると、直ぐにそれが目に見え難くなり、さらに、光触媒によって開始されるラジカル分解によって徐々に消失する。
1.より高活性な光触媒表面積を形成することができ、したがって、より高い光触媒活性を誘起することができる。
2.濡れに直接的効果を有する。粗さは実際に濡れ性を高める。滑らかな親水性表面は、粗くされるとより一層親水性になることができる。この場合、「粗さ」とは、表面の粗さと、層の厚さの少なくとも一部における層の多孔性によって生じる粗さの双方を意味するものと理解すべきである。
例1〜3
例1〜3は、液相熱分解法を用いて堆積させたコーティング3に関する。この操作は、フロートバス式チャンバーの出口のフロートガラスの横と上に配置した適切な分配ノズルを用い、連続的に行うことができる。この例においては、既に所定の寸法に切断した基材に相対して配置した可動性ノズルを用いて操作を非連続的に行い、この基材は、適切な溶液を噴霧するノズルを一定速度で通過させる前に、予め400〜650℃の温度までオーブンで加熱する。
例1
この例において、随意の層は存在しない。コーティング3は、2種類の溶媒の酢酸エチルとイソプロパノールの混合溶媒中に溶解させた、2種類の有機金属チタン前駆体のチタンジイソプロポキシドジアセチルアセトネートとチタンテトラオクチレングリコレートを含む溶液を用いて堆積させた。
例2
例1を踏襲したが、但し、基材1とコーティング3の間に厚さ73nmのSnO2:F層2を挿入した。この層は、ジブチル錫ジフロリドDBTF粉末の熱分解によって得られた。また、特許出願EP−A−0648196に記載のように、液相又は気相における熱分解による公知の方法によっても得ることができる。気相において、モノブチル錫トリクロリドとフッ化物前駆体(所望により、H2Oタイプの「マイルド」な酸化剤と組み合わせる)の混合物を使用することもできる。得られる層の屈折率は約1.9であった。その表面抵抗は約50Ωであった。
例3
例2を踏襲したが、但し、この例では、約1.75の屈折率と約50nmの厚さを有する酸炭化ケイ素を主成分とする層2を基材1とコーティング3の間に挿入し、この層は、特許出願EP−A−0518755に記載のように、窒素で希釈したSiH4とエチレンの混合物よりCVDによって得られる。この層は、基材1から生じるアルカリ金属(Na+,K+)やアルカリ土類金属(Ca++)がコーティング3の方に拡散する性向を防ぐのに特に有効であり、このため、光触媒活性が顕著に改良される。また、SnO2:Fと同様に、基材(1.52)とコーティング3(約2.30〜2.35)の中間の屈折率を有するため、反射と透過の双方において基材の着色強さを低下させることができ、この基材の光反射値RL を全体として低下させることができる。
例4〜7
例4
この例は、前述の特許出願EP−A−0518755に記載されているような、標準的ノズルを用いて基材1の上にCVDにより直接コーティング3を堆積させることに関する。前駆体として、有機金属化合物又は金属ハロゲン化物のいずれでも使用される。この例では、有機金属化合物としてチタンテトライソプロピレートを選んだが、この化合物は、高い揮発性と300〜650℃の広い使用可能温度のため有利である。この例において、約425℃で堆積を行い、TiO2の厚さは15nmであった。
例5
例4と同様にして行い、但し、この例では、15nmのTiO2層をガラス上に直接堆積させず、例3と同様にして堆積させた50nmのSiOC下層の上に堆積させた。
例6
例4と同様にして行い、但し、この例では、TiO2層の厚さは65nmであった。
例7
例5と同様にして行い、但し、この例ではTiO2層の厚さは60nmであった。
例8
この例では、「ディッピング」(「ディップコーティング」としても知られる)による堆積法を用いるゾルゲルを組合せた技術を使用した。この原理は図2に示されており、コーティング3の適切な1種以上の前駆体を含む液体溶液4の中に基材1を浸し、モーター装置5を用いてコントロールされた速度で基材1を引き上げた。引上速度の選定は、基材の2つの側の表面に残る溶液の厚さを調節することができ、したがって、溶媒を蒸発させて次いで前駆体を酸化物に分解させる熱処理の後のコーティングの厚さを調節することができる。
この例は、「セルコーティング」として知られる技術を使用し、その原理を図3に示した。これは、2つの実質的に平行な面の6と7、及び2つのシール8と9によって画定された狭いキャビティを形成することを含み、これらの面6と7の少なくとも1つは処理される基材1の面からなる。次いでキャビティが、コーティングの1種以上の前駆体の溶液4で満たされ、次いで濡れたメニスカスを形成するように、コントロールされた仕方で溶液4が抜き出され、例えばぜん動式ポンプ10を用い、この溶液が抜き出されたときに、基材1の面上に溶液の膜を残存させる。
−テスト1−
これは曇りについてのテストである。これは、濡れの後、光触媒とコーティングの構造(ヒドロキシル基、気孔率、粗さのレベル)の変化を観察することからなる。表面が光触媒性であると、コーティング上に付着した含炭素微細汚れ物質は継時的に分解され、表面は親水性であり、このため曇り防止性である。また、先にコーティングした基材を突然に再加熱し、冷間に置き又は単に基材に息を吹きつけ、曇りが現われるかどうかを観察し、現われるのであればその時間を測定し、その曇りが消えるまでに要する時間を測定する。
−テスト2−
これは、無垢のガラス表面に比較したコーティング3の表面の親水性と親油性の評価に関するものであり、自然光、暗闇の下で外界雰囲気に基材を1週間放置し、次いで紫外線に20分間曝した後、その表面での水滴とDOP(ジオフチルフタレート)の滴を測定することによる。
−テスト3−
これは、評価すべき基材の上に、オルガノシランの層を堆積し、紫外線(UVA)で照射し、光触媒によって分解させることからなる。オルガノシランは濡れ性を改良するため、照射の際の基材と水との接触角は、付着層の分解の状態を示す。この層の消失速度は、基材の光触媒活性に関係する。
