<アニオン及びカチオン濃度比の測定>
図1に示す試料調製の通りサンプルを斜めに切断し、飛行時間型2次イオン質量分析装置(TOF-SIMS)を用いて、上記外表面のアニオン濃度(Sa)と上記中間地点とのアニオン濃度(Da)とを測定し、その値から外気に接する膜の外表面と膜の内表面と外表面との中間地点のアニオン濃度比(Sa/Da)を求めた。
(分析装置と測定条件)
TOF-SIMS; ION・TOF社製 TOF-SIMS5
1次イオン; Bi32 + (加速電圧25kV)
測定面積; 400μm2
測定には帯電補正用中和銃を使用
(試料調製等)
図1に示す通りに、基材10の表面にコート層20が設けられたサンプルを切削方向30に向かって、精密斜め切削を行った後、10×10mm2程度の大きさに切り出し、測定面にメッシュを当て、サンプルホルダーに固定し、外気と接するコート層表面40および膜の内部であるコート層内部50(膜厚1/2の地点、基材10に接するコート層の内表面)で飛行時間型2次イオン質量分析装置(TOF-SIMS)を用いてアニオン濃度を測定した。
(評価)
評価は以下の計算式で行った。尚、各測定点のイオン濃度は、相対強度(トータル検出イオンに対する)を用いた。
<水接触角の測定>
