Environmental Applications of Electrospun Biopolymers and Multistructured Membranes

Spinning an spraying techniques represent an effective and economic tool for processing biopolymers membrane and multifunctional fibrous structures. Since the fiber morphology, diameter and patterning of fiber edeposition can be controlled, these technologies find a wide range of applications into bioengineering, with tissue scaffolds processing , drug delivery and wound dressing, energy and electronics, defense and security. In fact electrospun nanofibers has found to be a good candidate for advanced protective clothing for bio-warfare agents degradation. An other promising field regards the envinromental engineering, especially with filter membranes. This is because nanofiber filter media have enabled new levels of filtration and environmental clean up performances in a broad range of applications since they have proven to be a good candidate for promoting a significant increase in filter efficiency and life and more contaminate holding capacity. Unclean air which contains bacteria can be also purified using nano-size level fibrous membrane. Moreover electrospun bioresorbable polymer nanofibers could be used as an effective plant protecting agent.
