Abstract:
The objective of this dissertation is to propose the surface modification method for
preparing PDMS microfluidic devices with partially hydrophilic-hydrophobic surface for generating double emulsion droplets. The device is designed to be easy to use without any complicated preparation process and also to achieve high droplet encapsulation efficiency compared to conventional devices. The key component of this preparation process is the permanent chemical coating for which the Pluronic surfactant is added into the bulk PDMS.
The addition of Pluronic surfactant can modify the surface property of PDMS from the fully hydrophobic surface to the partially hydrophilic-hydrophobic surface whose property can be either hydrophilic or hydrophobic depending on the air- or water-treatment condition. In order
to control the surface wettability, this microfluidic device with the partially hydrophilic-hydrophobic surface undergoes the water treatment by injecting the deionized water into the specific microchannels where their surface property changes to hydrophilic. This microfluidic device is tested by generating water-in-oil-in-water (w/o/w) double emulsion micro-droplets in monodisperse for which the maximum droplet encapsulation efficiency of 92.4% is achieved with the averaged outer and inner diameters of 75.0 and 57.7 um, respectively. This
microfluidic device is designed without any complication in preparation of surface
modification process for higher efficiency compared to previous methods.
