シート抵抗の決定
シート抵抗は、リングプローブURS RMH214を搭載したHigh Resistivity Meter Model Hiresta − UX(Model MCP−HT 800)で測定した。測定は、100Vで行った。
コーティングの鉛筆硬度は、ISO 15184に従ってガラス板上に堆積したコーティングを横断して種々の硬度のさまざまな鉛筆を滑らせることによって行われる。コーティング上の鉛筆跡の可能な影響は、眼によって評価される。
コーティングされた基材の内部透過を、2チャネル分光計(Lambda900,PerkinElmer)で決定する。ここで散乱光の干渉を除外するために、試料は、光度計球(Ulbricht球)で測定され、その結果、散乱光および透過光が、光検出器によって検出される。したがって、透過は、コーティングおよび基材の吸収を意味すると理解される。純粋な基材の透過を、最初に測定する。厚さ175μmのMelinex 506フィルムを、基材として使用する。その後、コーティングされた基材を測定する。透過スペクトルは、可視光の範囲、すなわちステップ幅5nmで320nm〜780nmで記録される。
Clevios P VP CH 8000(Heraeus)(PEDOT/PSS重量比1:20;固形分:2.8重量%)を、表1に示すように種々の量の種々の溶媒と混合した(全て水に完全に可溶性)。例えば、試料2を得るために、95gのClevios P VP CH 8000を、5gのブチルグリコールと混合し、10分間撹拌した。分散体を、ノズル詰まりに関して試験した。試料をガラス基材上にスピンコートし、200℃で15分間乾燥した。シート抵抗を測定した。表1はその結果を要約したものである。本発明の試料2、3、4、5および6は、参照試料7および8と比較される。
タンニン酸0.1gを、エタノール84gに溶解する。12.6gのClevios P(Heraeus)を、250mlのガラスビーカーに入れる。タンニン酸のエタノール溶液を、撹拌下、Clevios P分散体に添加する。3.1gのテトラエチルオルトシリケートを、混合物に添加する。pHを、3.3に調整する。種々の量の追加の溶媒(表2に示される通り)を、分散体に添加した。混合物を、室温で30分間撹拌する。
Clevios P VP CH 8000を、3.24%固形分に濃縮した。種々の高沸点溶媒を、この「Clevios CH8000濃縮物」(PEDOT/PSS−重量比1:20;固形分:3.24重量%)に、種々の量で添加した。試料をガラス基材上にスピンコートし、200℃で15分間乾燥した。シート抵抗は、表3に示すように決定した。試料の層厚は、200nmであった。
