Synthesis of biomorphic ZnO derived from silk template
Natural silk fibers were used as the template to synthesis biomorphic ZnO fibers.Silk fibers were first immersed into a Zn(NO3)2 solution and then sintered in air at high temperatures to produce the final ZnO fibers.Their microstructures,phases,and synthesis process were analyzed.The results show that these synthesized fibers retained the morphologies of silk faithfully.The sintering temperatures had the effect on the continuity of the biomorphic fibers.The crystallite sizes of these biomorphic ZnO are in nano scale.The fabrication process of biomorphic ceramic included the formation of ZnO and removal of their silk templates.The ZnO formed before the removal of the silk-template,so that the fibrous morphology of the silk could be retained to this ZnO.The method of using bio-template could provide a new idea for the design of oxide fiber.
