Analysis of the effects of rotating roller speed on a roller electrospinning system

Popis výsledku v původním jazyce

The complexity of the free surface electrospinning process makes empirical determination of the effects of parameters very difficult. The parameters of the free surface-roller electrospinning process have not been fully defined. In this paper, new electrospinning parameters were suggested and studied. The relationship between rotating roller speed as a dependent parameter and independent parameter was investigated. The effects of rotating roller speed on electrospun nanofiber diameters and the quality of a nano web are determined experimentally. The velocity of the spinning roller and the content of salts in the solutions were selected as independent process parameters. The results show that the velocity of the rotating roller, which is related to the flow rate/feed rate of a solution on the surface of the rotating roller, affects the spinning performance as well as the quality of the fibers. Moreover, the spinnability and spinning behavior of polyurethane and polyethylene oxide solutions mainly depend on the salt content, viscosity and rotating roller speed. The high speed of the rotating roller caused a thick fiber diameter for the polyurethane solutions and polyethylene oxide, while the slow motion of the rotating roller caused low spinning performance. The diameters and diameter distribution of the electrospun nanofibers and quality of the nano web were most significantly affected by the speed of the rotating roller.
