Method and Process to Fabricate Hydrophobic Microchannels

Summary

Researchers at Purdue University have developed a new method of creating hydrophobic surfaces on polymers and metals for use in fabricating microfluidic devices with structured inner wall surfaces that provides control of flow rate in microfluidic channels. It may be used for applications where it is desired to have channels with a controllable flow rate, for microfluidic devices in which different channels have a different flow rate, or to separate different fluids or particles passing through the device. This technology may also be used in heat exchangers by removing condensed water drops, improving the heat transfer efficiency.
