Description
(1)酸化剤と、アミンまたはアミド重合抑制剤と、添加剤とを含む溶液を提供する工程であって、前記添加剤は水溶性ポリマーである工程、
(2)基板の表面に溶液を塗布して、酸化剤、重合抑制剤および添加剤の混合物層を基板の表面に形成する工程、
(3)酸化剤、重合抑制剤および添加剤を含有する層を蒸発させた複素環式芳香族モノマーに曝して、基板の表面へポリマー膜を形成することを進めるように重合を可能にする工程
を備える。
好ましい実施形態において、多層バリア(SiOxおよびSiNxのようなもの、ここで2>x>1および1.3>y>0.6である)を含むプラスチック膜基板を用いることができる。バリアは、プラスチック膜を通した酸素および水の透過を制限するため、およびその表面を平坦にするために用いることができる。
好ましい実施形態において、酸化剤、重合抑制剤および添加剤を含む溶液は、酸化剤および重合抑制剤を含む第1の溶液と、添加剤を含む第2の溶液とを調製し、次いで、第1および第2の溶液を混合することによって調製することができる。第1および第2の溶液は、同一または異なる溶媒を含むことができる。
第2の態様において、本発明は、本発明の第1の態様の方法により製造されたポリマー膜を提供する。第1の態様の好ましい特徴は、本発明の第2の態様に当てはまる。
VPP−PEDOT合成のための原料は、EDOTモノマー(H.C.StarkからのBaytron M)、p−トルエンスルホン酸・ヘプタン二酸鉄、ピリジン、グリセロール、ポリエチレンオキサイド(PEO、Mw6400)、ポリビニルアルコール(PVA,Mw7000〜10000)、メタノールおよびエタノール(シグマ−アルドリッチ)である。これらの原料は、市販されており、さらなる精製なしに使用された。ガラス基板は、20%Decon90および脱イオン(DI)水を用いて、超音波浴中でそれぞれ30分間洗浄した。
VPP−PEDOTの製造−PVA/PEO添加剤を用いた大量生産のための方法
溶液調製
まず、酸化剤溶液および添加剤溶液を調製し、次いでこれらの溶液を組み合わせることによって、酸化剤、重合抑制剤、およびポリマー添加剤を含む水溶液を調製した。PVAの使用のための酸化剤溶液(1)は、6gのp−トルエンスルホン酸・ヘプタン二酸鉄、0.2gのピリジン、0.8gのグリセロールを30gのイソ−プロパノールに溶解して得た。PEO使用のための酸化剤溶液(2)は、イソ−プロパノールをDI水に置き換え、溶液(1)中と同様の量で他の材料を保つことにより調製した。グリセロールは粘性の水親和性溶媒であり、酸化剤溶液の粘度を合わせるために配合される。PVA溶液は、3gのDI水に0.5gのPVAを溶解することにより、PEO溶液は3gのDI水に0.6gのPEOを溶解することにより得た。溶液は、80℃のホットプレート上で数時間攪拌し、0.2マイクロメーターのフィルターを通してろ過した。異なる濃度のPVAおよびPEO添加剤を含む酸化剤溶液は、下記表に示す比で上述した物質を混合することにより調整した。
比較のために、既知の合成経路を用いて、VPP−PEDOT膜を調製した。
酸化剤溶液は、0.6gのp−トルエンスルホン酸・ヘプタン二酸鉄および0.02gのピリジンを、3gのブタノール(またはブタノールとトルエンとの1:1混合溶液)中に溶解し、80℃のホットプレート上で1時間攪拌することにより調製した。酸化剤(p−トルエンスルホン酸鉄)層は、スピンコーティングによりガラス基板上に堆積した。乾燥は、80〜100℃まで加熱することにより行なった。
酸化剤層を有する基板は、真空の反応チャンバー内に移動した。酸化剤層を有する基板は、反応チャンバー内で気化したEDOTモノマーに曝した。EDOTモノマー蒸気が基板上の酸化剤層に接触する際、重合が生じ、それによって基板表面にPEDOT膜が形成される。
PEDOT膜を有する基板は、真空チャンバーから移動し、50℃のホットプレート上で30分間、次いで、エタノール/メタノール(1:1)溶液に3時間浸漬した。上にPEDOT膜を有する基板は、ゆっくりと溶液の外に出し、空気中で自然乾燥させた。VPP−PEDOT膜を有する基板は、膜全体が剥がれるのを避けるために静かに洗浄した。
ピンホールのない基板保護および高い導電率を有するVPP−PEDOT膜
一連のVPP−PEDOT薄膜を、例1で述べた既知の合成ルートを用いて準備し、17%のp−トルエンスルホン酸・ヘプタン二酸鉄と0.6%のピリジンとがトルエンとブタノールとの1:1溶液中に含有された酸化剤溶液から酸化剤含有層を堆積した。溶液中にはポリマー添加剤は存在しない。重合のための温度は、3から40℃まで変化させた。
