Single layer breathable nanowebs were developed using green electrospinning process. A team of interdisciplinary researchers at Texas Tech University involving fiber science, chemistry and toxicology have developed a homopolymer single layer porous nanoweb for bioengineering applications. The process involved water soluble poly (vinyl alcohol) and resulted in the development of standalone nanofiber webs. The process was devoid of any organic solvents and used heat cross-linking to obtain a stronger single layer nanoweb that can be handled for subsequent processes and treatments. The aim of the relatively environmentally friendly process was to avoid the use of cross-linking agents and functionalizing chemicals to obtain a stronger nanoweb. Heat cross-linked single layer nanowebs were good enough for handling and testing of their tensile and water transport properties. The nanowebs were approximately 250 nm in diameter.
