Chapter No: 5Conclusion and Prospective work5.1 ConclusionNature is a source of inspiration to develop new capabilities of artificial materials. As a non-contact, without a mask, low-cost technology, laser micro-nanofabrication provides an exciting platform for processing. It is worth noting that, compared with other processes, two unique features to ensure the future of this process. The first is not need fluoride treatment, laser processing can achieve large range of wetting characteristics, from the ultra-hydrophilic to super-hydrophobic, it can be used in biology to control cell behavior. The second is the laser processing natural introduction of nano-roughness, facilitates the generation of double-scale structure of super-hydrophobic structure --- level. Laser processing to obtain a variety of structures have recently been widely used in various fields, such as convertible smart stimuli-responsive surfaces, paper-based microfluidic devices, controlled biocompatible surface, all of which will be to promote femtosecond surface direct power laser micro-nanofabrication popularity.Based on the National Natural Science Foundation of China, around the femtosecond laser surface preparation invasive research, we have made some achievements. The main conclusions and contributions are summarized as follows:1) to explore the possibility of using the femtosecond laser micro nanofabrication lotus leaf superhydrophobic surfaces modeled prepared, and the successful use of direct-write technology integration femtosecond chemical treatment technology imitation lotus achieve self-cleaning surface preparation. The preparation of the surface projection cone cyclical microns, on which there are tens to hundreds of nanostructures embellishment on it. This structure not only demonstrates excellent static contact angle (close to 180 ), low rolling angle (
