In this study, electrospinning is a straightforward method to produce anfi-ultraviolet polymer fibers. The new types of anti-ultraviolet nano-fibers were produced by polylactic acid (PLA) and benzophenone-12. We also used different anfi-ultraviolet nano particles (TiO(2)) and others elements (Chemfos-168) with PLA. The structural and optical properties were investigated using (SEM) and Fourier transform infrared (FT-IR) spectroscopy. Results indicated that the benzophenone-12, Chemfos-168 and TiO(2) have potential to be composite fibers with PLA. The composite fibers with different elements and he best conditions were discussed by scanning electron microscope (SEM) observation.

In the study of biomimetic material design, mimicking nanostructured thin film components can take the place of the extracellular matrix. The new types of thin film were fabricated by polylactic acid (PLA) and Chlorhexidine composite nano-fibers with three different polylactic acid (PLA) to Chlorhexidine ratios (PLA: Chlorhexidine = 50:50 wt % and 90:10 wt %). The composite nano-fibers produced by electrospinning has high tensile strength. The materials analysis with nano-fibers was demonstrated via Fourier transform infrared (FT-IR) and scanning electron microscope (SEM). In the present study, we assessed the response of bacteria to different ratios of composite nano-fibers with regard to antibacterial activity and scanning electron microscope (SEM) observation. These results suggested that the composite nano-fibers have good antibacterial ability and release for a long period.
