RESUMO

Most solution electrospinning processes were performed at the ambient temperature. Few hot polymer solutions were used to produce electrospun nanofibers in the traditional electrospinning process, much less in electrospinning processes with a free liquid surface. In this presentation, poly(vinyl alcohol) solutions with different temperatures (20, 35, 50, and 65°C) were employed to fabricate nanofibers in a crater-like electrospinning process. All other electrospinning parameters, such as applied voltage, air pressure, and collective distance, were kept constant. The influence of solution temperature on the electrospinnability of solutions and the quality of prepared nanofibers were assessed. The results showed that the solution temperature exerted an appreciable influence on the viscosity of polymer solution, which in turn influenced the process of prediction of nanofibers and their quality. With increase in the solution temperature, the critical applied voltage and air pressure decreased. An ideal temperature is about 50°C for the production of nanofibers in these experiments. But a higher solution temperature caused a rapid evaporation of solvent in the solution, which caused aggravation of the solution electrospinnability.
