Description
以下の実施例を参照しながら、本発明をさらに詳しく説明する。
この配合では、EGDGEを50%純度として計算した。それは、1Hおよび13CNMR分光光度法により測定したものであって、アルドリッチ(Aldrich)からのEGDGEサンプル中の不純物には、さらなるエポキシド残基は含まれていなかった。全体のプロセスは以下のとおりである:試験管にEGDGE(174mg、1.0mmol、348mgの50%EGDGE)、ジェファミン(JEFFAMINE)(登録商標)T−403(391mg、0.89mmol)、および水(739mg)を仕込んだ。得られたポリマー前駆体を完全に混合し、室温で0〜45分間エージングさせた(表1参照)。次いでその反応混合物を型の中に注入し、70℃で1時間かけて硬化させた。硬化させた物質を含む型を熱から取り出し、放冷して室温とした。冷却後に、成形した物質を電解質の中で水和させて平衡状態として、アクチュエーターとしてすぐに使用可能とするか、または、その水和された物質を可撓性のある物質によって包み込んで、そのヒドロゲルアクチュエーターを除去、乾燥させることも可能である。
イオン性光活性化ポリマー(IPAP)は、ポリエーテルアミンおよびポリグリシジルエーテルの組成物に以下の物質を添加することによって調製したが、その理由は、それらが光誘導によるpHの変動、励起スペクトル、および比較的無害な性質を有していることがよく知られているからである:メチレンブルー0.05%溶液(アルドリッチ(Aldrich)製)λmax664nm、7−ジエチルアミノ−4−メチルクマリン(アルドリッチ・ケミカル・カンパニー(Aldrich Chemical Company)製)λmax390、および光酸発生剤(photo acid generator、PAG)ジフェニルヨードニウムペルフルオロ−1−ブタンスルホネート(アルドリッチ(Aldrich)製)λmax203nm。
7−ジエチルアミノ−4−メチルクマリンをポリEDGE(PolyEDGE)(アルドリッチ・ケミカル・カンパニー(Aldrich Chemical Company)製))にまず添加し、次いで、ジェファミン(JEFFAMINE)(登録商標)T403(ハンツマン・ケミカルズ(Huntsman Chemicals)製)およびH2Oを添加してクマリンIPAPヒドロゲルを配合したが、7−ジエチルアミノ−4−メチルクマリンは10mgおよび20mgでは十分に溶解したが、30mgおよび40mgの配合物では次第に残渣が残るようになり、40mgの場合には、型の底部に大きな塊状物が形成された。その液体をテフロン(Teflon)(登録商標)型の中に注入し、70℃で2時間かけて硬化させた。次いで、それらのゲルを24〜48時間放置して、空気乾燥させた。硬化プロセスの後に、蒸留H2Oを用いてそれらのゲルを水和させ、24時間かけて水で飽和させた。10〜20mgのゲルは透明な黄色を呈したが、30mgのゲルは、濁った黄色を呈し、40mgのゲルは、濁ったまだらな外観を呈し、型の底部で崩壊していた。
光酸発生剤IPAPヒドロゲルを以下のようにして配合した:10mgのジフェニルヨードニウムペルフルオロ−1−ブタンスルフェートをポリEDGE(PolyEDGE)に添加して十分に溶解させ、次いで、ジェファミン(JEFFAMINE)(登録商標)T403を加え、さらにH2Oを添加して重合を完了させた。次いで、その物質を型の中に注入し、70℃で2時間かけて硬化させた。次いでゲルを、24〜48時間放置して空気乾燥させてから、H2Oを用いて24時間かけて水和させたが、2個のサンプルを並べて、過塩素酸ナトリウムの0.1N溶液の中に浸漬させた。
上述のプロトコールに従って、メチレンブルー0.05%溶液を使用してメチレンブルーIPAPヒドロゲルを配合した。メチレンブルーは、H2O工程と共に、水性重合において、50%置換、次いで100%置換で添加した。次いで、その物質を型の中に注入し、70℃で2時間かけて硬化させた。次いでゲルを、24〜48時間放置して空気乾燥させてから、H2Oを用いて24時間かけてそれらのサンプルを水和させたが、2個のサンプルを並べて、過塩素酸ナトリウムの0.1N溶液の中に浸漬させた。
