The First-aid strip of copolymer, produced by electrospinning

Abstract

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.
