Description
本出願は2006年8月9日に出願の米国特許出願番号第11/463,507号に優先権を主張する。その文献の全体は引用により取り込まれている。
(連邦政府による資金提供を受けた研究又は開発)
米国政府は、国立科学財団によって与えられたGrant番号DMR-0213282に従って、本発明の特定の権利を有し得る。
(技術分野)
本発明は、超親水性被膜に関する。
透明な表面は、小さい水滴が表面に凝縮する時に曇る。そこで光が散乱され、通常、表面が半透明になる。曇りは多くの場合、冷えた表面が急に暖かい湿った空気と接触した時に生じる。重大な曇りは、最終的に透明材料の有用性を損なうことがある。場合によって、例えば、曇った材料が、車両フロントガラス又はゴーグルレンズである場合に、曇りは危険な状況になり得る。現在市販の防曇被膜は、大抵、繰返し洗浄後に時間とともに効果を失う。従って、それらの効果を保証するために常時再塗布が必要とされている。
安定な超親水性被膜は、ナノ粒子、高分子電解質又はこれらの組合せなどの交互積層構築膜(layer-by-layer assembled films)から形成することができる。超親水性被膜は、防曇性、防反射性、又は防曇性及び防反射性の双方を有することが可能である。該被膜は、高い透明度、高い防曇効率、長期環境安定性、高い耐擦傷性及び耐摩耗性、並びに高い機械的結着性を有することができる。好ましくは、単一の被膜は、これらの特性の組合せを有する。該被膜は、工業スケール技術を用いて、広面積基板に塗布することができ、安い製作コストにつながる。
ナノテクスチャーを有する表面は、極めて高い濡れ特性を示すことができる。ナノテクスチャーとは、ナノメートル(すなわち、典型的には、1マイクロメートル未満)の寸法を有する稜線、谷又は孔などの表面特徴を指す。場合によって、いくつかの個々の特徴が1マイクロメートルのサイズを超えていても、それらの特徴は、ナノメートルスケールの平均又はrms寸法を有することになる。ナノテクスチャーは、相互連結孔の三次元ネットワークであることができる。表面の構造及び化学組成に応じて、該表面は、親水性、疎水性、又は極端には超親水性若しくは超疎水性であることができる。所望のテクスチャーを形成するための1つの方法は、高分子電解質多層によるものである。また、高分子電解質多層は、防曇性、防反射性、又は所望範囲の波長の反射率などの所望の光学特性を表面に与えることができる。例えば、米国特許出願公開番号第2003/0215626号及び第2006/0029634号、並びに米国特許出願番号第11/268,547号を参照されたい。各文献の全体は引用により取り込まれている。
他の実施態様は、添付の請求項の範囲内である。
