Preparation and application of polymer nano-fiber doped with nano-particles

In recent years, the polymer nano-fiber behaves some novel optical properties by doping with some functional nano-particles, which prompts them to play an important role in the bio-chemical imaging and sensor areas. In this review, we have reviewed the preparation methods of the polymer nano-fibers, such as the electrospinning and one-step drawing technology, as well as the preparation processes and applications of the polymer nano-fibers doping systems containing different functional nano-particles. The low melting point of polymer nano-fiber leads to the easier preparation process. However, the susceptible corrosion to chemical and high temperature has limited its scope of application. In the future works, one should perfect the polymer nano-fibers devices by improving the production process and introducing new materials.
