Abstract
【解決手段】複合物品が、コア層103と、コア層の上に重なる上層105とを含み、上層105がフルオロポリマーと光触媒材料(PM)107とを含み、PM107が、上層105の外面の全面積の少なくとも約25%を画定する複合物品100。
【選択図】図1
Description
ここに記載されたようにメチレンブルーの色の変化を定量することによって光反応性を定量した。ここに記載された実施形態に従って3つの試料を形成し、複合シートを形成する条件などの様々な条件下で試料の光反応性を試験した。試料A、B、およびCは、約10〜40wt%のTiO2を含むPFAシートから形成される。試料Aは標準試験によって試験され、色の変化は約31の光反応性として測定される。試料Bは試料Aと同じであるが、しかしながら染料を加えた後、試料を熱に暴露して、例えば加熱して接合領域を形成する工程などの形成プロセスをシミュレートする。加熱プロセスは、試料を約680°Fの温度に30秒間保持する工程を含む。試料の色を再び試験によって測定した。
