Manufacturing of functional polymer micro- and nano-structures by femtosecond laser pulse

Due to their low-cost, comparable transparency and ease of preparation, polymers are widely used to fabricate various micro- and nano-structures for their applications in micro-optics, micro-fluidics, biomedical systems and so on. And in recent years, femtosecond (fs) laser direct writing process has become a popular tool to fabricate arbitrary three-dimensional (3D) microstructures with nanometer accuracies. Here we present fabricating polymer micro- and nano-structures via femtosecond laser. The tunable adhesive superhydrophobic surfaces achieved by femtosecond laser microprocessing may be potentially used in microfluidic systems to modulate the mobility of liquid droplets.
