Description
本明細書で使用する場合、
「不織」は、機械的、化学的、熱的、又は溶媒手段及びこれらの組み合わせによって達成される、繊維の結合若しくは連結、又はその両方によって製造されるテキスタイル構造を指し;
「織物」は、少なくとも2組のストランドが、通常は互いに直角に、所定のインターレースパターンに従って、かつ少なくとも1組は布地の長手方向に沿う軸に平行になるように織り合わされたときに作製される構造を指し;
「z軸」は、保護フィルムの平面に対して垂直な方向を指す。
例示的な保護フィルムが図1に示されており、本明細書において、符号100により表されている。保護フィルム100は、多層化されており、互いに反対側にある第1及び第2の主表面104、106を有する導電体102を含む。導体102は、第1のキャリア層112と第2のキャリア層114の間に配置される。選択した実施形態において、第1及び第2のキャリア層112、114は繊維質である。ここに示すように、第1及び第2のキャリア層112、114はそれぞれ織物材料を含む。
上記のように、提供された保護フィルムは、1つ以上の導体を含む。導体は、任意の好適な導電性材料、典型的には金属で作製され得る。一例として、導体は、保護フィルムが屈曲して非平面状の表面になじむことができる十分に薄い金属箔であってもよい。
本明細書に開示される保護フィルムは、導電性である1つ以上のキャリア層を含む。導電性を提供するため、本明細書に開示されるキャリア層は、複数の導電性繊維を含み得る。いくつかの実施形態では、導電性繊維は、導電性材料を均一に含む。代替的な実施形態では、導電性繊維は、非導電性繊維材料上に配置された導電性外層を含む。
有用な硬質化可能な組成物としては、硬化性熱硬化組成物が挙げられる。本明細書で使用する場合、「硬化性熱硬化組成物」は、架橋反応を起こすことができる化合物を指す。適切な開始剤及び/又は触媒を硬化性熱硬化組成物に含めることで、組成物が、例えば、加熱又は化学線(例えば、可視光又は紫外光)照射時に架橋できるようにすることができる。
任意に、保護フィルムは、好ましくは導電性である個別の部位を示す表面を含んでもよい。
