剥離層130(図1)、230(図2)の例示的実施形態は、フルオロポリマーを含む。本明細書に記載の配合物における使用に適切なフルオロポリマーは、フッ素含有ポリマーを含む。これらのポリマーは、ビニリデンフルオリド、ヘキサフルオロプロピレン、テトラフルオロエチレン、パーフルオロアルキルビニルエーテルおよびこれらの混合物からなる群から選択されるモノマー反復単位を含むフルオロポリマーを含む。該フルオロポリマーは、直鎖または分枝のポリマーおよび架橋フルオロエラストマーを含むことができる。フルオロポリマーの例は、ポリテトラフルオロエチレン(PTFE);パーフルオロアルコキシポリマー樹脂(PFA);テトラフルオロエチレン(TFE)およびヘキサフルオロプロピレン(HFP)のコポリマー;ヘキサフルオロプロピレン(HFP)およびビニリデンフルオリド(VDFまたはVF2)のコポリマー;テトラフルオロエチレン(TFE)、ビニリデンフルオリド(VDF)およびヘキサフルオロプロピレン(HFP)のターポリマー;ならびにテトラフルオロエチレン(TFE)、ビニリデンフルオリド(VF2)およびヘキサフルオロプロピレン(HFP)および硬化部位モノマーのターポリマーならびにこれらの混合物を含む。該フルオロポリマー粒子は、化学的安定性および熱安定性を提供し、低い表面エネルギーを有する。該フルオロポリマー粒子は、約255℃から約360℃または約280℃から約330℃の溶融温度または硬化温度を有する。これらの粒子は溶融または硬化して、剥離層を形成する。
場合により任意の公知および利用可能な適切な接着層が、剥離層130(図1)、230(図2)、中間層120(図1)、220(図2)および基材110(図1)、210(図2)の間に配置することができる。適切な接着層の例は、アミノシラン(例えばHV Primer10、Dow Corningなど)などのシラン、チタン酸塩、ジルコン酸塩、アルミン酸塩などおよびこれらの混合物を含む。一実施形態において、約0.001パーセントから約10パーセント溶液の接着層を、基材上にワイピングすることができる。該接着層は、基材上または外層上に、約2ナノメートルから約2,000ナノメートルまたは約2ナノメートルから約500ナノメートルの厚みにコーティングすることができる。該接着層は、スプレーコーティングまたはワイピングを含む任意の適切な公知の技術によりコーティングすることができる。
