Abstract
Active devices such as pumps and mixers have been fabricated in plastic-PDMS hybrid devices. By utilizing functionalized bis-silane primers, bond strength between Polycarbonate or PMMA and PDMS improved in dry and aqueous environments. Plastic-primer-PDMS layers exposed to acid and base solutions at 70° C. for 2 hours showed no signs of delamination at 30 psi for pH −1 to 15 and 60 psi for pH 0 to 15. A peristaltic pump fabricated in polycarbonate achieved consistent flow rates up to peristaltic cycle frequencies of 10 Hz in water, 1OM HCl, and 1OM NaOH solutions.
