5.HFIP基とアルキル基を有するポリイミドの合成
本発明の気体分離膜に使用するHFIP基とアルキル基を有するポリイミドを合成方法について説明する。
このようにして得られたHFIP基とアルキル基を有するポリイミドの溶液は、気体分離膜製造にそのまま用いることもできる。また、HFIP基とアルキル基を有するポリイミドの溶液中に含まれる残存モノマー、低分子量体を除去する目的で、水またはアルコール等の貧溶媒中に、HFIP基とアルキル基を有するポリイミドの溶液を加え、HFIP基とアルキル基を有するポリイミドを沈殿させて単離精製した後、改めて有機溶媒に前記濃度になるように溶解させて調整してもよい。
本発明のHFIP基とアルキル基を有するポリイミドを含む気体分離膜は、HFIP基とアルキル基を有するポリイミド溶液から溶媒が蒸発することを利用して薄膜を作製する湿式成膜法で得られる均質膜、または他の方法で得られる緻密層と多孔質層とを有する非対称膜のいずれであってもよい。
均質膜は、例えば、前述のHFIP基とアルキル基を有するポリイミドの溶液を、ガラス基板などの基体にスピンコーター、アプリケーター等を用いて湿式被覆した後、空気、窒素またはアルゴン等の乾燥気体中で加熱し、溶剤を蒸発させた後、ガラス基材から剥離させることで得られる。また、HFIP基とアルキル基を有するポリイミド溶液の代わりに、HFIP基とアルキル基を有するポリアミド酸溶液を用いて、上記手順で基体に被覆させた後、加熱してイミド化させることでも均質な膜を得ることもできる。
緻密層と多孔質層とを有する非対称な膜は、前述の方法で成膜することができる。また、ポリイミド溶液の代わりに、ポリアミド酸溶液を用いて非対称膜を形成した後、熱イミド化させることでも、非対称膜を得ることができる。
本発明の気体分離膜に使用する、HFIP基とアルキル基を有するポリイミドは、極性基であるHFIP基の含有効果により、アミド系溶媒であるN,N−ジメチルアセトアミド、N,N−ジメチルホルムアミドまたはN−メチル−2−ピロリドン、ラクトンであるγ−ブチロラクトン、γ−バレロラクトンに特に溶解し易く、所望の膜厚を有する均質膜を作製することも容易であるし、水系凝固液を使用した非対称膜を作製することも容易である。
作製した気体分離膜の表面欠陥を修復することを目的として、シリコーン樹脂を分離膜表面にコーティングしてもよい。コーティング方法としては、スピンコーティング、アプリケーターによるコーティング、浸漬コーティングなど、公知のコーティング法を使用することができる。
前記一般式(1)で表される繰り返し単位を有する高分子化合物は、機械強度または耐可塑性を向上させる目的で、発明6〜9の気体分離膜のように、エポキシ化合物と混合し、加熱または光照射などにより硬化させて硬化膜とすることができる。当該硬化膜は、前記の均質膜、および非対称膜にも適用可能である。
で表されるエポキシ化合物は、これに対応するアルコールとエピクロロヒドリンから合成される。
気体分離膜用のHFIP基とアルキル基を有するポリイミド膜の調製について説明する。
前記のN,N−ジメチルアセトアミド溶液をガラス基板上に塗布し、スピンコーターを用いて、回転速度:1000rpm、保持時間:30sec.の塗布条件でスピンコートした。得られたガラス基板を、窒素雰囲気下、200℃、1時間加熱処理した後、ガラス基板から剥がすことで、ポリイミド1から得られる膜、即ち、HFIP基とアルキル基を有するポリイミド1膜(以下、「ポリイミド膜1」と表すことがある。)を得た。膜厚を測定したところ、25μmであった。
ポリイミド5に対し、ガス透過係数の測定および分離性能の評価を行った。以下に気体分離膜のガス透過性能の測定方法を示す。
