Researchers at University of Shanghai for Science and Technology Target Nanofibers

May 7, 2014



By a News Reporter-Staff News Editor at Biotech Week -- Investigators discuss new findings in Nanofibers. According to news reporting from Shanghai, People's Republic of China, by NewsRx journalists, research stated, "The influence of different types of solvents as sheath fluids on the quality of electrospun ethyl cellulose (EC) nanofibers is investigated in this paper by a modified coaxial process. With 24 w/v % EC in ethanol as electrospinning core fluid and pure solvents including methanol, ethanol and N,N-dimethyl formamide (DMF) as sheath fluids, EC nanofibers were generated by the modified processes."

The news correspondents obtained a quote from the research from the University of Shanghai for Science and Technology, "Field emission scanning electron microscope observations demonstrate that the modified process is effective in improving the nanofibers' quality in terms of nanofibers' diameters, distributions and structural uniformity. The key of the modified coaxial process is the reasonable selection of the sheath solvents that is suitable for the drawing process of core EC fluid during the electrpospinning. The EC nanofibers' diameters (D, nm) could be manipulated through the reasonable selection of the type of the sheath solvents based on their boiling point (T, °C) D=841-3.71T (R=0.9753)."

According to the news reporters, the research concluded: "This paper provides useful methods for the implementation of the modified coaxial process controllably to obtain polymer nanofibers with high quality."
