疎水性フッ素化溶媒と、
疎水性フッ素化ポリマーを含む結合剤と、
疎水性ヒュームドシリカナノ粒子と、
任意選択で、疎水性エアロゲルナノ粒子と、を含む、組成物を提供する。
(a)疎水性フッ素化溶媒、疎水性フッ素化ポリマーを含む結合剤、ヒュームドシリカナノ粒子、および任意選択で、疎水性エアロゲルナノ粒子を組み合わせることと、
(b)組み合わせを混合することと、

非晶質フルオロポリマー結合剤を、フッ素化溶媒中に溶解する。疎水性ヒュームドシリカナノ粒子を添加する。任意選択で、疎水性エアロゲルナノ粒子を添加する。混合物を音波プローブで混合して、疎水性ヒュームドシリカ粒子および疎水性エアロゲル粒子の集塊を破壊し、乾燥させて所望の材料を提供する。表1は、例示的な組成物および組成物の重量パーセントとしての各成分の量を列挙している。
疎水性シランを微量の水とイソプロピルアルコールまたはアセトンとの混合物に添加して、1体積%のシラン溶液を提供する。任意選択でプラズマエッチングされたガラスウエハーを溶液に浸漬し、次に、空気乾燥してからオーブンにて約100℃で約15~20分間加熱し、シラン官能化表面を提供する。
フッ素化溶媒中の2重量%のフルオロポリマー結合剤および架橋シランのコーティング溶液を、プラズマエッチングされたガラスウエハー上にスピンコーティングして、150~450nmのコーティングを提供する。コーティングされたウエハーを空気乾燥してから、オーブンにて約150℃で約60分間加熱して、架橋コーティング層を提供する。
フルオロポリマー結合剤の層を、物理蒸着(PVD)を使用して、任意選択によりプラズマエッチングされたガラスウエハー上に堆積させる。堆積に続いて、実施例2または3によるナノ粒子コーティング溶液を、コーティングされたウエハー上に噴霧して、コーティング層に部分的に埋め込まれたナノ粒子を提供する。ウエハーを空気乾燥し、次に、オーブンにて150~200℃で60分間加熱する。
