Abstract

Polydimethylsiloxane (PDMS) has been widely used for a material of µTAS devices due to the superior nature of manufacturability, chemical resistance, etc. This paper reports a new method to control the water-vapor permeability of PDMS by dispersing collagen powder. We designed and fabricated micro-fluidic devices to directly measure the amount of water-vapor permeating through PDMS and evaluated the effect of dispersed collagen. The water-vapor permeability of PDMS was successfully reduced by the dispersed collagen powder by 54%.
