This scanning electron microscope image, created by Sadhan C. Jana and Sepideh Niknezhad, shows a collection of fluffy polyvinylacetate (PVAc) fibers of mean diameter 200 nm. The fibers are produced by gas jet spinning of a solution of 14 (w/w)% PVAc in dimethyl formamide, delivered through a cylindrical nozzle. The fluffy fiber mats are good candidates for wound dressing materials. The research article discusses interpenetrating network morphology, core‐shell arrangement, and bilobal organization of two immiscible polymers (PVAc and polyvinylpyrrolidone) in the same fiber via gas jet spinning process. The fluffiness of the mats allows easy transport of oxygen and moisture and compatibility with wound contours. DOI: 10.1002/app.48901
