単量体化合物を上記液中で重合するためには、単量体化合物とポリアニオンとを含む分散液、または単量体化合物とポリアニオンにより保護コロイド化されたシード粒子とを含む分散液(以下、併せて単に「単量体化合物液」と称すことがある。)を調製する。
単量体化合物の重合に用いられる水性媒体は、共役系導電性重合体とポリアニオンにより保護コロイド化されたシード粒子との複合体、共役系導電性重合体とポリアニオンとの複合体、またはこれら2種の複合体を分散させることができるものであれば特に限定されないが、シード粒子の分散液に用いた水性媒体と同じ種類のものが好ましい。
水溶性溶媒としては、例えば、N-ビニルピロリドン、ヘキサメチルホスホルトリアミド、N-ビニルホルムアミド、N-ビニルアセトアミド等のアミド類;クレゾール、フェノール、キシレノール等のフェノール類;メタノール、エタノール、イソプロピルアルコール等の一価アルコール類;エチレングリコール、プロピレングリコール、ジプロピレングリコール、1,3-ブチレングリコール、1,4-ブチレングリコール、ジグリセリン、イソプレングリコール、ブタンジオール、1,5-ペンタンジオール、1,6-ヘキサンジオール、1,9-ノナンジオール、ネオペンチルグリコール等の多価アルコール類;アセトン等のケトン類;エチレンカーボネート、プロピレンカーボネート等のカーボネート化合物;ジオキサン、ジエチルエーテル、プロピレングリコールジアルキルエーテル、ポリエチレングリコールジアルキルエーテル、ポリプロピレングリコールジアルキルエーテル、エチレングリコールモノメチルエーテル、エチレングリコールモノブチルエーテル等のエーテル類;3-メチル-2-オキサゾリジノン等の複素環化合物;アセトニトリル、グルタロジニトリル、メトキシアセトニトリル、プロピオニトリル、ベンゾニトリル等のニトリル類が挙げられる。これらの溶媒は、1種単独でまたは2種以上を組み合わせて用いることができる。
上記単量体化合物の重合において、例えば、ポリピロール類やポリチオフェン類を共役系導電性重合体として含む分散液を製造する場合、酸化剤の存在下に単量体化合物液を所定の温度にすることによって重合が開始される。
上記酸化剤は、1種単独でまたは2種以上を組み合わせて用いることができる。
上記単量体化合物の重合時の温度は通常、5~80℃であり、好ましくは10~60℃であり、より好ましくは15~40℃である。重合時の温度をこの範囲内にすると、適度な反応速度で重合を行うことができ、反応液の粘度の上昇を抑えることができ、共役系導電性重合体を含む分散液の製造を安定的に経済的な時間で行うことができ、かつ得られる共役系導電性重合体の導電率が高くなる傾向がある。重合時の温度は、公知のヒータやクーラを用いることにより管理することができる。また、必要に応じ、上記範囲内で温度を変化させながら重合を行ってもよい。
上記単量体化合物と保護コロイド化されたシード粒子とを含む分散液を用いた上記単量体化合物の重合中に、反応液にポリアニオンにより保護コロイド化されたシード粒子の分散液をさらに添加することが好ましい。上記単量体化合物の重合中に、所定量の保護コロイド化されたシード粒子の分散液をさらに添加することにより、重合時の反応液の増粘を抑制でき撹拌混合効率の向上や製造装置への負荷を低減することができる。重合中に添加する保護コロイド化されたシード粒子の分散液の量は、使用する保護コロイド化されたシード粒子の分散液の総量の10~90質量%が好ましく、20~80質量%がより好ましく、30~70質量%がさらに好ましい。
上記単量体化合物の重合中に、反応液にポリアニオンをさらに添加してもよい。上記単量体化合物の重合中に所定量のポリアニオンの一部をさらに添加することにより重合時の反応液の増粘を抑制でき撹拌混合効率の向上や製造装置への負荷を低減することができる。重合中に添加するポリアニオンの量は、使用するポリアニオンの総量の0~90質量%が好ましく、20~80質量%がより好ましく、30~70質量%がさらに好ましい。
工程(A)では、上記のように共役系導電性重合体を含む分散液(1)を調製すると共に、前記分散液(1)に分散処理を施すことで、前記共役系導電性重合体を含有する分散液(2)(以下「共役系導電性重合体含有分散液(2)」ともいう。)を得る。
前記共役系導電性重合体を含む分散液(1)は、(i)共役系導電性重合体とポリアニオンとの複合体、および(ii)共役系導電性重合体とポリアニオンにより保護コロイド化されたシード粒子との複合体、から選択される少なくとも一つが水性媒体中に分散した分散液である。
固体電解コンデンサの静電容量およびESRの向上のためには(つまり、固体電解コンデンサの静電容量を大きくし、ESRを低減させるためには)、多孔性陽極体への含浸性を向上させる必要があるため、本発明においては、工程(A)において複合体を解砕し、平均粒子径が1~10μmの微粒子が分散された状態とする。
分散処理は、前記複合体を前記微粒子の大きさまで解砕するものであり、ホモジナイザー等の強力な撹拌装置や超音波照射によって行うことが好ましい。分散処理は前記重合性化合物を重合する際に行ってもよい。すなわち、分散処理が施される分散液(1)には、未反応の前記重合性化合物が含まれていてもよい。例えば、特開2007-332183号公報にはせん断速度5,000s-1以上で撹拌しながら共役系導電性重合体を重合させる方法が記載されている。
高圧ホモジナイザーを使用する場合、高圧ホモジナイザーの圧力は、好ましくは10~2000barであり、より好ましくは20~1500barであり、さらに好ましくは50~1000barである。高圧ホモジナイザーの圧力が10bar以上であれば、分散処理が効率的に行われ、固体電解コンデンサの性能が良好である。高圧ホモジナイザーの圧力が2000bar以下であれば、分散処理の際の作業性が良好である。
分散処理を行うときの分散液(1)中の共役系導電性重合体の濃度は、分散処理における生産性を損なわない範囲で、とくに限定はされないが、固体電解コンデンサへの含浸性の観点から、仕上がりの濃度、すなわち工程(A)により得られる分散液(2)中の共役系導電性重合体の濃度は1.0~10.0質量%が好ましい。1.0質量%以上であれば、固体電解コンデンサのESRが良好である(つまり、ESRをより低くすることができる。)。10.0質量%以下であれば、静電容量が良好である(つまり、静電容量をより大きくすることができる。)。
工程(A)においては、前記分散処理を一時停止する操作が1回以上、合計1~6000分行われる。
一時的に前記分散処理を停止し、分散液(1)を静置することで、分散していた複合体および/またはその解砕物(以下「複合体等」とも記載する。)は凝集し、分散液(1)は増粘する。増粘後に再度分散処理を行うことで、複合体等の解凝集を促進させることができる。
1回あたりの一時停止の時間としては、1~300分が好ましく、2~150分がより好ましく、5~75分がさらに好ましい。分散処理を一時停止する時間が1分以上であれば、分散処理が効率的に行われ、良好な性能の固体電解コンデンサが製造される。
増粘させた分散液の粘度(たとえば、一時停止終了時の粘度)は、好ましくは、増粘させる前の粘度(たとえば、一時停止開始時の粘度)の1.05~100.0倍の粘度であり、さらに好ましくは1.10~50.0倍の粘度であり、より好ましくは1.50~50.0倍の粘度であり、特に好ましくは3.00~50.0倍の粘度であり、上限はたとえば15倍であってもよい。増粘後の分散液の粘度が増粘させる前の粘度の1.05倍以上であれば、共役系導電性重合体の解凝集が効率的に行われ、固体電解コンデンサの性能が良好である。増粘後の分散液の粘度が増粘させる前の粘度の100.0倍以下であれば、分散処理の効率性が良好である。
工程(A)において、水性媒体に塩化合物を添加することもできる。塩化合物の添加により分散液のイオン強度を高め、分散していた複合体を凝集させ、分散液(1)をさらに増粘させることが可能となる。
例えば、水性媒体に溶解し、分散液のイオン強度を高め、分散液を増粘させる無機塩及び有機塩から選ばれる少なくとも一種の塩化合物であることが好ましい。
共役系導電性重合体を含む分散液(1)には、必要に応じて種々の添加剤を添加することができる。添加剤は、共役系導電性重合体、及びポリアニオンにより保護コロイド化されたシード粒子若しくはポリアニオンと混合しうるものであれば特に制限されない。
酸化防止剤としては、例えば、フェノール系酸化防止剤、アミン系酸化防止剤、リン系酸化防止剤、硫黄系酸化防止剤、糖類、ビタミン類が挙げられる。
分散液(1)が塩を含む場合には、前記分散処理を終えた後に分散液(1)を脱塩してもよい。工程(A)で一次粒子まで分散された共役系導電性重合体及びポリアニオンの複合体は、脱塩することにより静置しても分散性を保つことができる。
脱塩の方法に特に制限は無く、透析法、遠心分離洗浄法、イオン交換法等により脱塩を行うことができる。
本発明の固体電解コンデンサの製造方法は、前述の工程(A)で得られた共役系導電性重合体含有分散液(2)を、弁金属からなる陽極体と、該陽極体表面の少なくとも一部に形成された誘電体被膜とを有する多孔性陽極体の表面に付着させる工程(B)を有する。
弁金属からなる多孔性電極は、例えば、陽極酸化によって表面に誘電体酸化被膜を形成し、多孔性陽極体とする。
浸漬時間は、通常10秒~5分間であり、共役系導電性重合体含有分散液(2)の温度は、水性媒体の種類にもよるが通常10~35℃である。
本発明の固体電解コンデンサの製造方法は、前述の工程(B)で得られた多孔性陽極体に付着した共役系導電性重合体含有分散液(2)から、水性媒体を除去し固体電解質層を形成する工程(C)を有する。本工程(C)における水性媒体の除去は、水性媒体の全てを除去することを意味するものでなく、固体電解コンデンサの製造に影響しない範囲で水性媒体が一部残存してもいて差し支えない。
各例の固形分濃度は、各例で得られた試料10gを、赤外線水分計((株)ケツト科学研究所製、形式FD-720、加熱条件110℃/30分)を用いて測定し、蒸発残分を固形分として計算した。

重量平均分子量は、ゲル浸透クロマトグラフィーを用いて測定した。測定には昭和電工(株)製の「Shodex(登録商標) GPC 101」(カラム OHPak SB-806M HQ)を用い、測定条件はカラム温度40℃、溶出液は水、溶出速度1ml/分とした。重量平均分子量を標準ポリスチレン換算分子量(Mw)で表示した。
固体電解コンデンサ素子の120Hzでの静電容量(μF)および100kHzでの等価直列抵抗〔ESR〕(mΩ)を、LCRメーター(Agilent製、型式E4980A)を用いて測定した。
(ポリアニオンで保護コロイド化されたシード粒子の分散液の作製)
スチレン86g、2-エチルヘキシルアクリレート49g、ジビニルベンゼン15g及びポリスチレンスルホン酸ナトリウム(東ソー有機化学株式会社製、ポリナスPS-5、重量平均分子量:約120,000)22質量%水溶液500gを撹拌混合し、エチレン性不飽和単量体混合液を調製した。一方、ポリスチレンスルホン酸ナトリウム(同上)22質量%水溶液1000gを撹拌しながら、80℃に昇温し、これに過硫酸カリウム2gを添加した。こうして得られた溶液に、前記エチレン性不飽和単量体混合液及び過硫酸カリウム2.5質量%水溶液40gを、それぞれ、2時間及び2.5時間かけて滴下した。滴下終了後、反応液を80℃で2時間保持し、その後、室温(25℃)まで冷却した。得られた反応液に陽イオン交換樹脂(オルガノ株式会社製、IR120B-H)1500ml及び陰イオン交換樹脂(オルガノ株式会社製、IRA410-OH)1500mlを添加し、12時間撹拌した後、イオン交換樹脂をろ別した。ろ液にイオン交換水(以下、単に水と言う。)を添加して固形分濃度が15.0質量%となるように調整し、ポリアニオンで保護コロイド化されたシード粒子(粒径d50:0.46μm)の分散液を得た。
ポリエチレン製容器内で、水223.2質量部、ポリスチレンスルホン酸ナトリウム(同上)12質量%水溶液31.5質量部、及び上記のとおり作製したポリアニオンで保護コロイド化されたシード粒子の分散液34.0質量部を32℃で撹拌混合した。この混合液に、32℃で3,4-エチレンジオキシチオフェン2.80質量部を添加して、ホモミキサー(特殊機化工業株式会社製、ロボミックス;4000rpm)で30分間乳化混合し、単量体化合物分散液を調製した。3,4-エチレンジオキシチオフェン1モルに対するスルホ基およびスルホ基の塩からなる基の量は1.9モルであった。なお、前記スルホ基等は、ポリスチレンスルホン酸ナトリウム12質量%水溶液及び前記分散液中のポリスチレンスルホン酸ナトリウム由来のものである。
固形分濃度5.80質量%の前記分散液(1-1)に、純水を加えて、固形分濃度4.73質量%、全量1500mLに調整した。その後、分散液(1-1)(以下、前記分散液(1-1)、およびこれに各種操作(純水の添加、高圧分散処理、イオン交換等)を施したものを、区別することなく「分散液(1-1)」と記載する(ただし、最終生成物である分散液(2-1)を除く。)。)を、高圧ホモジナイザー(TWIN PANDA 600、Niro Soavi社製)により分散圧力を400barとして合計45分間高圧分散処理した。この高圧分散処理では、9分間の高圧分散処理と10分間の一時停止とを4回繰り返し、最後に9分間の高圧分散処理を行った。最後の一時停止開始時の分散液(1-1)の粘度は900mPa・s、最後の一時停止終了時の分散液(1-1)の粘度は4500mPa・sと、一時停止開始時の5.0倍であった。その後純水を加えて分散液(1-1)を固形分濃度3.99質量%、全量1500mLに調整し、再度分散液(1-1)を、高圧ホモジナイザーにより400barで一時停止をすることなく135分間高圧分散処理し、その直後に陽イオン交換樹脂100.5gおよび陰イオン交換樹脂87.9gにより3時間イオン交換し、脱塩させた。その後、分散液(1-1)を孔径が5μmのフィルターで濾過した後、さらに孔径が3μmのフィルターで濾過し、純水を加えて固形分濃度1.60質量%に調整することで、pH1.9の、共役系導電性重合体の分散液(2-1)を得た。
