Description

【特許請求の範囲】
【請求項１】
自己清浄性表面を含む物品であって、ＵＶ線に暴露した時に光触媒性となる離散した粒子を含み、前記粒子が約５ｎｍから約１００ｎｍの範囲の平均直径を有する、前記物品。
【請求項２】
前記自己清浄性表面が可動物である、請求項１記載の物品。
【請求項３】
前記粒子がＴｉＯ2を含む、請求項１記載の物品。
【請求項４】
前記粒子が、粒子の少なくとも約９５パーセントが平均直径の約６０パーセント以上及び平均直径の約１４０パーセント以下の直径を有するような直径分布を有する、請求項１記載の物品。
【請求項５】
前記粒子が約５ｎｍから約５０ｎｍの範囲の平均直径を有する、請求項１記載の物品。
【請求項６】
流体を純化する方法であって、ＵＶ線に暴露した時に光触媒性となる離散した粒子を含む表面に前記流体を接触させる工程を含み、前記粒子が約５ｎｍから約１００ｎｍの範囲の平均直径を有し、前記表面がＵＶ線に晒される、前記純化方法。
【請求項７】
硬質表面を清浄化する方法であって、硬質表面をＵＶ線に暴露する工程を含み、前記硬質表面がＵＶ線に暴露した時に光触媒性となる離散した粒子を含み、前記粒子が約５ｎｍから約１００ｎｍの範囲の平均直径を有する、前記清浄化方法。
【請求項８】
前記粒子が、粒子の少なくとも約９５パーセントが平均直径の約６０パーセント以上及び平均直径の約１４０パーセント以下の直径を有するような直径分布を有する、請求項６または７記載の方法。
【請求項９】
光活性組成物と金属酸化物を含む粒子とを含むフォトレジスト組成物であって、前記粒子が約５ｎｍから約１５０ｎｍの範囲の平均直径を有する、前記組成物。
反応は、ポンプがもはやフィルター２５２の抵抗に対して反応室１０４の所望の圧力を維持できなくなるほど、フィルター２５２に充分なナノ粒子が収集されるまで継続することができる。反応室１０４の圧力を所望の値に維持できなくなった時、反応を停止し、そしてフィルター２５２を取り外す。この態様において、１回の実行で反応室の圧力を維持できなくなる前に、約３−７５グラムのナノ粒子を収集することができる。１回の実行は、製造する粒子の型及び特定のフィルターにもよるが、一般的に約１０分ないし約３時間継続する。従って巨視的量のナノ粒子、即ち、肉眼で見える量を製造することは簡単である。
