Poly(dimethylsiloxane) (PDMS) microfluidic device is naturally hydrophobic and hard to produce oil phase polymer particle. Surface modification of PDMS was performed by photo-irradiation (UV and O2 Plasma) method. We tried to make long-term stability of hydrophilic polymer coated PDMS microfluidic device and tried to produce oil droplets. 2-hydroxyethylmethacrylate (2-HEMA) solution was injected into modified PDMS microfluidic device and the coated PDMS surface was treated by oxygen plasma. PDMS surface has many formed with C-O bonding with 2-HEMA which was confirmed by ATR-FTIR spectroscopy. Contact angle was 6° and coating thickness was 19.76 μm. Stability was continuing for 2 weeks (2-HEMA+O2 plasma coating: 6°→46°/O2 plasma: 5°→84°). We performed production Undecanol droplet experiment into the hydrophilic microfluidic device. Undecanol droplet was produced and droplet size was 14.91μm.
