摘要：

Cast molding is a simple, low cost microfabrication method which offers the potential to fabricate microstructures in a large variety of polymer materials. We discuss some characterizations of a cast molding technique which exploits the use of polydimethylsiloxane as a mold material. The suitability of this process for microfluidic systems with five different polymers was studied by observing the mold sticking properties, pattern transfer resolution, and effects on surface roughness and surface wettability. The process yielded excellent results for all polymers, suggesting the suitability of cast molding as a general purpose microfabrication technique for polymers. Surface wettability was modified for some polymers.
