Study on Behaviour of Polymer Solutions in Electrospinning Technology

摘要

Electrospinning has become during the last few years a promising method for obtaining long and continuous fibers, with nanometer diameters, from a great variety of polymers. The applications range from performant filtering mediums or membranes, to driving sensors or systems, to medical textiles and medicines controlled-delivery to molecular photonics. This work presents polymer solutions with different concentrations of polyetherimide (PEI) in the range 8-14%, ratio 1:1 of dimethylacetamide - tetrahydrofuran (DMA/THF), which were studied taking in consideration the physical characteristics (superficial tension, conductivity and viscosity). These characteristics were analyzed in correlation with electrospinning technology and morphological and structural properties of obtained fibers.
