New Polymer Physics Study Findings Have Been Reported from Zhongyuan University of Technology (Mass Preparation of Nanofibers by High Pressure Air-Jet Split Electrospinning: Effect of Electric Field)

By a News Reporter-Staff News Editor at Physics Week -- Investigators publish new report on Polymer Physics. According to news reporting originating from Zhengzhou, People's Republic of China, by VerticalNews correspondents, research stated, "A novel electrospinning method using airflow, namely high pressure air-jet split electrospinning, was proposed to fabricate polymer nanofibers with ultrahigh production rate. 7 wt % polyacrylonitrile spinning solution with a 0.157 Pa s viscosity was divided into micron size droplets by the filter screen in the front of the nozzle, and then these droplets were divided and split through high pressure airflow, which were drafted into nanofibers directly in the electric field and airflow field. In this study, the electric field distributions with different positive electrodes were simulated and their effect on fiber formation was investigated."

Our news editors obtained a quote from the research from the Zhongyuan University of Technology, "The results show that electric field distribution and its intensity depended on electrodes area, a broader electric field distribution with a stronger intensity would bring about a larger cone angle of spraying jet region, at the same time, the contrast in the spray region enhanced. When the whole nozzle was charged, thinner fibers with about 170 nm could be prepared and the fiber production was 75.6 g/h."

According to the news editors, the research concluded: "Compared with the conventional needle electrospinning, the throughput of nanofibers could be improved by thousands of times based on this novel electrospinning method."
