Abstract
- This paper reports a new fabrication method of polydimethylsiloxane (PDMS) microlenses with various curvatures by using a water-based mold. The hydrophobic surface of Polypropylene (PP) substrate was modified by corona discharge using tesla coil to have hydrophilic surface. Then hydrophilic surface of PP substrate takes hydrophobic recovery to have various contact angles from less than to about . By using the water droplets with various contact angles as replica molds for PDMS process, we could obtain PDMS microlenses with various curvatures.
