Formation of Oriented, Suspended Fibers by Melting Free Standing Polystyrene Thin Films
A new approach toward the fabrication of oriented, suspended fibers from the melting of free standing polymer thin films is presented. Thin films (between 35 and 120 nm) cast via flow coating are melted atop lithographically patterned arrays of pillars to form suspended fibers (from similar to 2 to 3 mu m in diameter) between pillars, The effects of film thickness and pillar spacing on fiber diameter and yield are probed in a combinatorial fashion. A novel image analysis technique for the acquisition of fiber diameter across the multivariable parameter space is also outlined. This thin film melting approach details a new technique toward the fabrication of oriented, suspended micro and nanofiber networks with specific point to point connections in desired architectures.
