Morphological and mechanical response characterization of nanofiber aggregates of pva produced by electrospinning sol-gel process

This work deals with the preparation of poly (vinyl alcohol) solutions composed of a surface active agent, an acid and water. With this solution firstly electrospun nanofiber mats and then nanofiber aggregates were obtained by electrospinning/sol-gel process. The samples were morphologically charact...
