Description
パターンI:[全面未処理流路]
流路全壁面・・・処理(a) CA=67°
パターンII:[全面超親水性流路]
流路全壁面・・・処理(b) CA=10°
パターIII:[部分的超親水性流路]
流路断面右半分・・・処理(b) CA=10°
流路断面左半分・・・処理(c) CA=144°
I))では、滴下速度10μL/sにおいて、流路断面は直ちに純水で満たされ流路を閉塞し
た。また、流路中の純水の一団は液滴の供給がある時は下流方向に移動したが、液滴の供給が停止している時は流路に留まり下降せず流路を閉塞した。
水は滴下速度57μL/sにおいても流路断面を満たすことなく下流方向へ流れた。マイクロピペット先端から吐出した液滴は流路壁面に接すると瞬時にその球形の形状が破壊され流路内に濡れ広がった。このことが、流路断面を占める純水の面積を低減させ、流路閉塞を抑制したと考えられる。
、滴下速度57μL/sにおいて流路断面が純水で満たされることは無かった。超親水性の部分に瞬時に濡れ広がった液滴は、その後水流となり、流路内面左半分の撥水性部分(CA=144°)に浸入することなく超親水性部分を選択的に下流まで流れた。
