STUDY OF RHEOLOGICAL BEHAVIOUR OF POLYMER SOLUTION USED FOR ELECTROSPINNING PROCES
The electrospinning process is a way to produce nanofibers that can be used with a wide variety of polymer. It consists in introducing a polymer solution into a high voltage field via a metallic needle. This solution is submitted to a high stretch effect which transforms droplet into nanofibers. To obtain nanofibers, it is important to control the process conditions. In the process parameters, the solution properties; in terms of viscosity is crucial to the spinnability. To precisely define the electrospinnability of the polymer, our researches have been focused on evaluation of the solution behavior through rheological characterization. In our studies, two solutions Polyacrylonitrile/ Dimethylformamide and Polyamide/Formic acid have been rheologicaly tested, during the flow state for different concentrations. Thanks to these results, the electrospinability of each solution could be known as well as the physical and mechanical behavior of the resultant nanofibers.
