Abstract

© 2014TRF. A commercially available Janus paper with one hydrophobic (polyethylene-coated) face and a hygroscopic/hydrophilic one is irreversibly bonded to a PDMS substrate incorporating microfluidic channels via corona discharge surface treatment. The bond strength between the polymer coated side and PDMS is characterized as a function of corona treatment time and annealing temperature/time. A maximum strength of 392 kPa is obtained with a 2 min corona treatment followed by 60 min of annealing at 120 ºC. The water contact angle of the corona-treated polymer side decreases with increased discharge duration from 98º to 22º. The hygroscopic/hydrophilic side is coated with hydrogel to show its potential for nutrient and chemical delivery in cell culture applications.
