摘要
It is developed a novel light induced surface modification methods for PDMS based microfluidic devices using an incoherent vacuum ultraviolet (VUV) light. PDMS surface is exposed with VUV light in order to control hydrophilicity, zeta-potential, bonding strength, etc. that are all executed under atmospheric conditions. The VUV light induced chemical changes are investigated by X-ray photoelectron spectroscopy (XPS) which indicates the change from the PDMS to SiO2-like chemical composition. Additionally, as an evaluation of VUV light based fabrication, a simple electrostatic on-off valve is developed.
