Design Process of Electrospun Lightweight Thermo-Insulating Material

Nanofibers being the main unit of electrospun materials have paid attention in the last decades as their potential applications are increasing each day. In this work single and blend polymers solutions were prepared from polyurethane (PU), poly(ethylene oxide) (PEO) and (PU/PEO). The solutions were electrospun into porous microstructures and evaluated with regard to their fiber diameter and pore area distribution using SEM analysis. The mean fiber diameter and pore area decreased for almost 200 nm and 4 µm2 respectively, for both dual polymer electrospun systems, influenced by the water extracted amount of the water soluble PEO. Statistically the difference showed significance, but an inverse effect for the pore area as expected was not reached due to wet fibers agglutination.
