Evaluation of Processing Parameters in the Synthesis of Silica Nanofibers Doped with Silver by the Solution Blow Spinning Method

Abstract

The ceramic fibers can be obtained from different techniques. Due to the technological development, searches are performed to improve the existing fibers. Thus, recent studies have enabled the development of an unprecedented synthesis route for the production of nanofibers, the Solution Blow Spinning (SBS). In this context, the present work proposes to develop silica nanofibers doped with silver by the SBS method, evaluating parameters such as: silver content and acidification of solutions. The fibers were characterized by X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). The results of XRD showed that the samples with 4% silver that were not acidified showed the most defined and intense characteristic peaks. The SEM showed the formation of fibers with diameters in the nanometer range independent of acidification or not of the solutions, with reduction of the agglomerates in the samples with 2% silver.
