초록
본 연구에서는 표면특성에 따른 비균일계 마이크로채널에서의 유속 변화를 조사하였다. 비균일계 마이크로채널은 PDMS와 soft lithography를 사용하여 제작하였고, 마이크로채널의 내부 표면 중 아랫면만을 allyl alcohol로 증착하여 친수성을 띠게 하였다. 채널의 길이는 10, 20, 30 mm, 너비는 100, 200,
This study investigated the flow rate changes of the heterogeneous rectangular microchannels which have different hydrophilic property on the bottom surface. The heterogeneous rectangular microchannel has three native PDMS (poly-dimethyl siloxane) surfaces which were patterned by the soft lithography. PDMS bottom surface was treated by the argon plasma and coated by the allyl alcohol (99%). The channel length was 10, 20 and 30 mm and the channel width was 100, 200 and
