AgNPs Improved Feather Keratin Based Bio-Membrane


 AgNPs (Silver Nanoparticles) is successfully prepared and then loaded into feather keratin (FK) based bio-membrane by electrospinning. The morphology, thermal stability, mechanical properties and bacteriostatic activity of the as-prepared AgNPs/FK/PVA bio-membrane are completely developed in this study. Microstructure show that the AgNPs has been dispersed in FK-based bio-membrane without agglomeration. The results suggest that the addition of AgNPs enhanced effectively the performances of FK-based bio-membrane, and the appropriate amount of AgNPs is 1%-2%. The combination of AgNPs and FK can not only ensure the uniform dispersion and antibacterial stability of AgNPs, but also give play to the biocompatibility effect of FK, which makes it natural, safe, stable and degradable, and broaden its application in the field of biomedicine.
