This research is to fabricate the PMMA microstructured capillaries as microfluid channels by drawing method. The diameter of microstructured capillaries is 300 μm and the diameter of the inner hole is 45 μm. In the experiment, plasma was used as surface treatment apparatus and modified the surface of microstructured capillaries. The study try to make the surface become wettability and help the liquid to flow in the capillaries by measuring the difference of the time the liquid flow through the capillaries treated by plasma. Depending on the factors of plasma generation include different gas, gas flow, RF power and time treatment, there are many conditions will occur on the surface of PMMA. It is inspected that the wetting angle will become small after plasma treatment. On the surface of PMMA appears the needle-like structure in the nanometer scale after plasma treatment with low RF power and low flow rate O2 , it will increase the wetting angle. When the RF power increasing, ion bombardment makes the surface become smooth and the wetting angle decrease, the wettability would be improved. On the other hand, the hydrophilic functional group will be produced on the surface after O2 and N2 plasma treatment with high RF power, it helps improve the wettability without the affect of enviroment. The wetting angle of PMMA surface treated by low RF power in Ar plasma is bigger than in O2 and N2 plasma treatment, the most reason why is that without chemical etching and less hydrophilic functional group produced on the surface.
