Description
本開示に含まれる図面は、本開示の実施形態を例示し、明細書とともに、本開示の原理を説明するのに役立つ。図面は、特定の実施形態を例示するだけであり、開示を限定するものではない。
当業者は、図2、図3、および図4に示される特定の実施形態が同一のコネクタ継手を有し、或る実施形態では、コネクタ継手は、様々なサイズを有し得、降圧(step-down)または昇圧(step-up)継手などの様々な設計を有し得るか、または様々なタイプの作動構成要素210上に配置され得ることを理解するであろう。
[共押出処理]
本開示に記載されている導電性ポリマーストライプを有する管セグメントは、様々な共押出し処理を使用して作製することができる。例えば、図8aに示される管セグメント800aは、管セグメントの外部または外径に導電性ストライプ802aおよび804aを含み、管セグメントの内部または内径に導電性ストライプ806aを含む。別の実施形態では、図8bは、管セグメントの内部に導電性ストライプ802bを有する管セグメント800bを示し、導電性ストライプ802bは管セグメントの軸方向の長さに沿って延びる螺旋状のストライプである。別の実施形態では、図8cは、管セグメントの外側および内側の両方に導電性ストライプ802cおよび804cを有する管セグメント800cを示し、導電性ストライプ802cおよび804cは管セグメントの長さに沿って軸方向に沿って延びる螺旋状のストライプである。さらに別の実施形態では、図8dは、管セグメントの外側に導電性ストライプ802dを有する管セグメント800dを示し、導電性ストライプ802dは管セグメントの長さに沿って軸方向に沿って延びる螺旋状のストライプである。
この実施例は、以下の[テーブル1]に示される導電性材料および非導電性材料を含む管セグメントに、脱イオン水(deionaized water:脱イオン化水)を流すことによって生成される静電気の量を測定した。静電気の測定は、発生した電荷をファラデーカップで収集および測定するための既知の方法を使用して行われた。
