Microfluidic device fabrication has classically utilized methods that have limited devices to specific applications. More recently, discrete microfluidic elements have reimagined the design process of microfluidic device fabrication to that of building blocks that can be constructed in various forms to produce devices of many applications. Here, surface modification of discrete microfluidic elements via initiated chemical vapor deposition is demonstrated. Coated modular elements can quickly assemble to form complex 2-D or 3-D structures with step-like surface energy gradients for applications requiring discrete control of channel surface wettability. This platform is applied toward the generation of double emulsions to show the ease of design and manufacturing over existing methods developed to manage two-phase flows.
